Power Supplies R Series RTW(50 to 100W)
AC Input
Single Output, General-Purpose UL/CSA/TÜV Approved
This is an ultra-thin, high-performance standard power supply that
is both energy efficient and environmentally friendly. Utilizing
TDK’s unique material, mounting, noise reduction and thermal
analysis simulation technologies, these products have been
reduced by 50% and 60% in volume and weight respectively com-
pared to existing TDK products. All components are lead-free and
compatible with the environmental assessment program.
Highly efficient 5V, 100W type products deliver 83% efficiency
(with 100V input)
FEATURES
• Conforms to EN61000E-3-2 regulations for high harmonic cur-
rents.
• Wide input (AC.100-200) No toggling required.
• Conforms to EMS standards EN61000-4-2, 3, 4, 5, 6, 8 and 11.
• Conforms to FCC-B and VCCI-B regulations for radiating and
transmission noise.
•CE certified.
• Approved by safety standards (UL, CSA and TÜV). Conforms to
the Electrical Appliance and Material Safety Law.
• 5-year limited warrantee.
• Life span of electrolytic capacitor: 60,000hrs. or more.
• Lead-free.
• Does not use designated bromine flameproof material (PBPEs
and PBBs).
• Available in 1U and 2U rack sizes.
These are particularly suited for situations that call for thin prod-
ucts. They are designed so that they can be attached on both
sides.
• The remote control feature (which was optional in previous prod-
ucts) is now standard and can be used by toggling an internal
switch.
APPLICATIONS
• Semiconductor fabrication equipment
• LED displays
• Wire and wireless communication equipment
• Other industrial equipment

REMOTE SENSING
Remote Sensing compensates to provide stability at the load ter-
minal when voltage drop in the line between the power supply and
the load causes instability. Remote sensing is possible if the volt-
age drop per wire between the output and load terminals is 0.25V
max. for 5.0V models and 0.4V max. for 12 to 48V models.
Make sure that the power supply’s output voltage and power
remains within the range of the output specifications. Pulse loads
and other situations where sudden changes in the load can occur
may not conform to the dynamic load change specifications.
Take out the short-circuit plates of the +S/+ terminal and the –S/–
terminal and wire them as shown in the figure below. The sensing
lines must be either shielded or twisted (The recommended length
is 5m (max.)).
In case of parasitic oscillation or overvoltage protection malfunc-
tion too easily, install an external electrolytic capacitor, rated 470µF
min. between the +OUT, +S and –OUT, –S terminals.
REMOTE ON-OFF
Turn the remote on/off switch located at the center of the power
supply to "Y" (clockwise) to enable the remote control.
The output voltage can be turned on and off from an external
source by inputting the signal indicated below between the remote
on/off terminals (+RC and –RC).
Output voltage is turned on when the level is high between the
+RC and –RC terminals (external voltage application of 4.5 to
24.5V).∗
Output voltage is turned off when the level is low between the +RC
and –RC terminals (short or terminal voltage of 0 to 0.8V).
∗Use an external resistor (1.5kΩ) when applying an external volt-
age of 12.5-24.5V.
±RC terminals are insulated from AC input terminals and the DC
output terminals.
Insulation between the ±RC terminals and the output conforms to
the common specifications (Output to case). Withstand voltage
between AC input terminals and ±RC terminals conforms to the
common specifications (Input to case).
INSULATION AND WITHSTAND VOLTAGE TESTS
The insulation and withstand voltage tests may cause deteriora-
tion. Care must be taken for execution of the tests. The potential
must be equal among input, output, and FG (frame ground) termi-
nals. It is preferable to use testers which gently start up at the test-
ON and automatically discharge charging energy at the test-OFF.
Manual discharging after the tests should be through a resistor
around 100kΩ to 1MΩ (Do not perform discharging at low imped-
ance. It may cause deterioration.).
In any case, take full countermeasures for electric-shock preven-
tion.

PRECAUTIONS
•When using this unit, make sure that the ambient temperature of
the power supply is within the operating temperature range. The
"ambient temperature of the power supply" refers to the temper-
ature near the power supply inside the device in which the unit is
installed.
•If natural cooling is used, install the unit in such a way that a
thermal convection is created. Additionally, space the power
supply at least 10 mm away from other components on all sides.
•Make sure to choose input/output wiring and noise filters that
can safely accommodate their respective current capacities.
•If the power supply is not used for extended periods of time, we
recommend that you apply input voltage for about one hour
every two years to maintain the capacitor’s performance.
•When power supplies are used serially, the rated current will be
limited by the power supply with the lowest rated current. Also
make sure to connect a reverse voltage protection diode (With-
stand voltage: twice that of the combined output voltage. For-
ward current: twice that of the output current. Forward voltage
drop: as small as possible) to prevent damage to the interior
components caused by reverse voltage.
•The materials used in these products are free of designated bro-
mine flameproof materials (PBDPEs and PBBs).
•Specific ODS has not been used in the production of these prod-
ucts.
