Specifications
■Ratings/Characteristics
Note: 1. Do not use the Inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the Power
Supply may result in ignition or burning.
2. Refer to the Engineering Data (15-W, 30-W, 50-W, 100-W, 150-W Models) section on page 9 to 11 for details.
3. If the V. ADJ adjuster is turned, the voltage will increase by more than +20% of the voltage adjustment range.
When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged.
4. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.
5. Conducted emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under
the Power Supply. For 15-W models, insert a clamp filter (ZCAT2436-1330 by TDK: 50 Ω min. [50 to 500 MHz], or the equivalent) in the output wire to reduce noise.
6. Radiated emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under the
Power Supply. For 150-W models, insert a clamp filter (ZCAT2017-0930 by TDK: 35 Ω min. [50 to 500 MHz], or the equivalent) in the input wire to reduce noise.
7. The weight indicated is for bottom mounting, open-frame models.

Engineering Data (15-W, 30-W, 50-W, 100-W, 150-W Models)
■Derating Curve
300W/600W/1,500W
Note: Refer to page 15.
Note: 1. Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply in areas outside the derating curves (i.e., the area shown by
shading A in the above graphs).
2. If there is a derating problem, use forced air-cooling.
3. When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them. Multiple 100- and 150-W models cannot be used
side by side. Be sure to install the Power Supplies as far away from heat-generating sources as possible. As a reference value, allow at least 50 mm spacing
on the right and left sides. If only 20 mm spacing is allowed, use the Power Supply at a load ratio of 80% or less.
4. When using 150-W models for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above derating curves.

■Mounting
Note: 1. Improper mounting will interfere with heat dissipation and
may occasionally result in deterioration or damage of inter-
nal parts.
Use the Power Supply within the derating curve for the
mounting direction that is used.
2. Use the metal plate as the mounting panel (*1).
3. Install the Power Supply so that the air flow circulates
around the Power Supply, as the Power Supply is designed
to radiate heat by means of natural air flow.
4. Mounting screw tightening torque
(recommended value: M3 (0.49 N·m))
■Remote Sensing Function
(S8VM-100@@@@/150@@@@ only)
This function compensates a voltage drop on the load lines.
To use this function, connect after removing the two short bars of the
remote sensing terminal.
Note: 1. Use a 2-conductor shielded cable as a connection wire (*1).
2. Use as thick a wire as possible since high voltage drops on
the load lines (*2) may activate the overvoltage protection
function.
3. Use when the voltage drop is 0.3 V or lower.
4. When the +S and −S terminals are opened with the short
bar removed, the overvoltage protection function is activat-
ed and the output voltage will be cut off.
5. If the load line is too long, use an electrolytic capacitor in the
following 3 locations:
1) Across the load terminals
2) Between the +S terminal and + terminal
3) Between the −S terminal and − terminal
Select the capacity of the connected capacitor from be-
tween several tens to several hundreds of µF as a guide,
and then determine the capacity when actually connecting
the capacitor between terminals as shown below.

MTBF stands for Mean Time Between Failures, which
is calculated according to the probability of accidental
device failures, and indicates the reliability of a device.
Therefore, it does not necessarily represent the life of
the Power Supply.
Life

Switch Mode Power Supply S8VM 11
■Overload Protection
The Power Supply is provided with an overload protection function
that protects the Power Supply from possible damage by short-circuit
and overcurrent.
When the output current rises above 105% min. of the rated current,
the protection function is triggered, automatically decreasing the out-
put voltage. When the output current falls within the rated range, the
overload protection function is automatically cleared.
The values shown in the above diagrams are for reference only.
Note: 1. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or other overcurrent state continues dur-
ing operation.
Eliminate the overcurrent state as soon as possible.
2. Internal parts may possibly be deteriorated or damaged if the
Power Supply is used for applications with frequent inrush cur-
rent or overloading at the load end. Do not use the Power Supply
for such applications.
■Overvoltage Protection
Consider the possibility of an overvoltage and design the system so
that the load will not be subjected to an excessive voltage even if the
feedback circuit in the Power Supply fails. When an excessive
voltage that is approximately 140% of the rated voltage or more is
output, the output voltage is shut OFF, preventing damage to the load
due to overvoltage. Reset the input power by turning it OFF for at
least three minutes and then turning it back ON again.
The values shown in the above diagram are for reference only.
*1 S8VM-@@@24A@/P@
*2 Except for S8VM-@@@24A@/P@
Note: 1. Do not turn ON the input power again until the cause of the
overvoltage has been removed.
2. The overvoltage protection function may be activated when
the output voltage adjuster (V.ADJ) is set to a value that ex-
ceeds +20% of the rated output voltage.
■Undervoltage Alarm Function (Indication and Output)
(Only S8VM-@@@24A@/P@)
If an output voltage drop is detected with an S8VM-@@@24A@/P@ with undervoltage alarm function, the DC LOW indicator will light to notify of an
output error. The transistor also sends an output externally to notify of the error (except for the S8VM-01524A@ and S8VM-03024A@).
Transistor Output: Sinking type: (NPN) (S8VM-@@@24A@)
Sourcing type: (PNP) (S8VM-@@@24P@)
30 VDC max., 50 mA max., Residual voltage when ON: 2 V or less, Leakage current when OFF: 0.1 mA or less
•Undervoltage Alarm Function 1 (DC LOW1)
Only a momentary voltage drop is detected. Detection voltage is automatically adjusted internally by detecting the output voltage (approx. 2.7 V
lower than the voltage output at an output voltage of 24.0 V).
During detection, the transistor is OFF (with no continuity across 8 and 10) and the LED (6: Yellow) lights. (The Undervoltage Alarm Function 1 is
used as a latch holding function.)
•Undervoltage Alarm Function 2 (DC LOW2)
Detection voltage is set to approx. 20.0 V (from 18.0 to 21.6 V).
During detection, the transistor is OFF (with no continuity across 9 and 10) and the LED (7: Red) lights.
Note: 1. This function monitors the voltage at the Power Supply output terminals.
To check actual voltage, measure voltage on the load side.
2. Gradual voltage drop is not detected by the Undervoltage Alarm Function 1 (DC LOW1).
3. Once undervoltage is detected by Undervoltage Alarm Function 1 (DC LOW1), the transistor turns OFF and status of the LED (6: Yellow)
light is maintained. To reset the function, turn OFF the input power for 60 seconds or longer, and then turn it ON again.
4. If the output voltage remains at 15 V or lower for several seconds when using Undervoltage Alarm Function 1 (DC LOW 1), the output
hold status for detection may be reset.

Probable cause of error Troubleshooting methods
--- --- 1
A momentary power failure has occurred in the
input.
Check that the output voltage is normal and no problems have occurred in other devices. No problems
will be caused by continuing to use the Power Supply as is. To clear DC LOW1 (LED display and tran-
sistor output status), turn OFF the input power, and wait at least 60 s before turning ON the input Power
Supply again.
2
A momentary overload has occurred. The load current has probably exceeded the rated current. We suggest reducing the connected load
or replace the Power Supply with one that has a higher capacity.
A momentary output voltage drop has occurred
at startup due to the capacity of the capacitive
factors on the load side or when the load is acti-
vated.
A large inrush current has probably flowed to the load side at startup. We suggest replacing the Power
Supply with one that has a higher capacity.
The output voltage has returned to normal volt-
age following a rapid drop caused by using the
output voltage adjuster (V.ADJ).
Turn OFF the input power, and wait at least 60 s before turning ON the input power again to clear the
indicator status.
Deterioration due to age (when the Power Sup-
ply has been used for several years)
The internal parts of the Power Supply may have deteriorated due to age. We suggest replacing the
Power Supply. Also replace other Power Supplies that were purchased at the same time.
3
Overload (immediately following first use of the
Power Supply or when increasing the load)
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
The output voltage dropped to -10% or lower of
the rated voltage resulting from using the output
voltage adjuster (V.ADJ)
Adjust the output voltage to the rated values using the output voltage adjuster (V.ADJ).
A sudden overload occurred and the Power
Supply remains in overload status.
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device. Continued use in overload status may damage the Power Sup-
ply.
4
The output voltage remains low after a rapid
voltage drop caused by using the output voltage
adjuster (V.ADJ).
Adjust the output voltage to the rated values using the output voltage adjuster (V.ADJ). To clear DC
LOW1 (LED display and transistor output status), turn OFF the input power, and wait at least 60 s be-
fore turning ON the input power again.
The overload status continues to fluctuate fol-
lowing a sudden overload.
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device. Continued use in overload status may damage the Power Sup-
ply. 5
Deterioration due to age (after using the Power
Supply for several years)
The internal parts of the Power Supply may have deteriorated due to age. Replace the Power Supply.
Also replace other Power Supplies that were purchased at the same time.
6
Overload (immediately following first use of the
Power Supply or when increasing the load)
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
Power Supply interrupted or damaged. Check whether the input power is being applied correctly. If there is no output even though the input
power is applied correctly, the internal circuit is probably damaged.
7
Overvoltage protection operation Turn OFF the input power, and wait at least 3 min before turning ON the input power again. If the same
status recurs, the internal circuit is probably damaged.
The short bar has fallen off, or the +S and -S ter-
minals are open.
Check whether the +S and -S terminals are open. If so, the overvoltage protection function is activated.
Therefore, turn OFF the input power and wait at least three minutes before turning it ON again. (S8VM-
10024A@/P@ and S8VM-15024A@/P@ models only)
Output short-circuit Remove the cause of the output short-circuit.
Intermittent operation due to overload (S8VM-
01524A@/03024A@ only)
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
8
The Power Supply fails to start repeatedly due
to the capacity of the capacitive factors on the
load side.
A large inrush current has probably flowed to the load side at startup. We suggest replacing the Power
Supply with one that has a higher capacity.
The input turns ON and OFF repeatedly. Check whether the Power Supply’s input voltage is being applied correctly.
The status repeatedly switches between normal
operation and output short-circuit.
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device.

■Output Color Label
This color label identifies the output voltage by color.
Note: A 300-W model is shown above. The label is in a different place
on 600-W models and 1,500-W model.
Note: 1. The fuse is located on the (L) side. It is NOT user-replace-
able.
2. Protective earthing connection is the panel mounting hole of
the metal case. (A protective earthing connection stipulated
in safety standards is used. Connect the ground complete-
ly).
Ground terminal: M4 (Depth: 6 mm max.)/Ground wire:
AWG 18
3. The enclosed standard connector for signal I/O is mounted
to CN when S8VM is shipped. The enclosed signal I/O con-
nector shorts between 1 and 2, between 3 and 4, and be-
tween 7 and 8.
Do not connect a load to the output voltage monitor termi-
nals (+V, -V).

Engineering Data (300-W, 600-W, 1,500-W Models)
■Derating Curve
300W/600W/1,500W
Note: 1. Internal parts may occasionally be deteriorated or dam-
aged. Do not use the Power Supply in areas outside the de-
rating curves (i.e., the area shown by shading A in the
above graph).
2. When mounting two or more Power Supplies side-by-side,
allow at least 20 mm spacing between them. Always provide
at least 50 mm of mounting space for the surface with the
fan mounted. Be sure to provide at least 50 mm (S8VM-
300@@C/600@@C) or 100 mm (S8VM-15224C) of mount-
ing space on the opposite
