Engineering Data
De-rating
Note
1. Power supply components may degrade, or
be damaged,
when the power supply is
continuously used outside the shaded region,
refer to the graph shown in Fig. 1.
2. If the output capacity is not reduced when the
surrounding air temperature >55
°C, the
device may run into Over Temperature
Protection. When activated,
the output
voltage will go into latch-
off mode and
recoverabl e by AC power recycle.
3.
In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance of 25mm with adjacent units
while the device is in operation.
4. D
epending on the surrounding air
temperature and output load delivered by the
power supply, the device can be very hot!
5. If the device has to be mounted in any other
orientation, please do not hesitate to contact
info@deltapsu.com f or more detai ls.

The power supply unit (PSU) can be mounted on 35mm DIN rails in accordance with EN60715. The device should be installed with
input terminal block at the bottom.
Each device is delivered ready to install.

Dismounting
Fig. 2.1 Mounting
Snap on the DIN rail as shown in Fig. 2.1:
1. Tilt the unit upwards and insert it onto the DIN rail .
2. Push downwards until stopped.
3. Press against the bottom fr ont side for lockin g.
4. Shake the unit slightly to ensure that it is secured.
Fig. 2.2 Dismounting
To uninstall, pull or slide down the latch with screw driver as
shown in Fig. 2.2. Then sli de the power supply unit (PSU) in
the opposite direction, release the latch and pull out the power
supply unit (PSU) from the rail.

Safety Instruc ti ons
Functions
■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
Start-up Time
The time required for the output voltage to reach 90% of its set value, after the input voltage is applied.
Rise Time
The time required for the output voltage to change from 10% to 90% of its s et value.
Hold-up Time
Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time
required for the output to reach 90% of its set value, after th e input volt age is remov ed .
– ALW AYS switch mains of input power OFF before connecting and disconnecting the input
voltage to the unit. If mains are not turned OFF, there is risk of explosion / severe damage.
– To guarantee sufficient convection cooling, keep a distance of 50mm above and
below the device as well as a lateral distance of 25mm to other units.
– Note that the enclosure of the device can become very hot depending on the surrounding
air temperature and load of the power supply. Risk of burns!
– DO NOT insert any objects into the unit.
– Hazardous voltages may be present for up to 5 minutes after the input mains voltage is
disconnected. Do not touch the unit during this time.
– The power supplies unit should be installed in minimum IP54 rated enclosure.
–
The power supplies are built in units and must be installed in a cabinet or room
(condensation free environment and indoor location) that is relatively free of conductive
contaminants.

Inrush Current
Inrush current is the peak, instantaneous, input current measured
and, occurs when the input voltage is first applied. For AC input
voltages, the maximum peak value of inrush current will occur
during the first half cycle of the applied AC voltage. This peak
value decreases exponentially during subsequent cycles of AC
voltage.
Dynamic Response
The power supply output voltage will remains within ±5% of its
steady state value, when subjected to a dynamic load from 10 to
100% of its rated current.
Overvolt age Prot ec tio n
The power supply’s overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specific ations defined on Page 3 under “Protections”.
Overload & Overc ur rent Protecti ons
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated when output current rapidly exceeds
105% of IO (Max load). In such occurrence, once the power
supply has reached its maximum power limit, the protection is
activated and the power supply will go into “Hiccup mode” (Auto-
Recovery). The power supply will recover once the fault condition
of the OLP and OCP is removed and IO is back within the
specifications.
Over Temperature Protection
As mentioned above, the power supply also has Over
Temperature Protection (OTP). In the event of a higher operating
condition at 100% load, the power supply will run into OTP when
the operating temperature is beyond what is recommended in the
de-rating graph. When activated, the output voltage will go into
latch-off mode until the component temperature cools down and
the AC power is recycled.
Short Circuit Protection
The power supply’s output OLP/OCP function also provides
protection against short circuits. When a short circuit is applied,
the output current will operate in “Hiccup mode”, as shown in the
illustration in the OLP/OCP section on this page. The power
supply will return to normal operation after the short circuit is
removed.
