Assembly & Installation
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.
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 fron t side for locking.
4. Shake the unit slightly to ensure that it is secured.
To uninstall, pull or slide down the latch with screw driver as
shown in Fig. 2.2. Then slide the power supply unit (PSU) in
the opposite direction, release the latch and pull out the power
supply unit (PSU) from the rail.

Functions
■ Graph illustrating the Start-up Time, Rise Time, and Hold-up Ti me
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 set value.
Hold-up Time
Hold up time is the time when the AC input collapses and output voltage r etains regulation f or a cer tain peri od of time. The time
required for the output to reach 90% of its set value, after the input voltage is removed.

□
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.
Overload & Overcurrent Protections
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated when output current ra pidl y ex ceed s

the output current will operate in “Hiccup mode”, as shown in the
illustration in the OLP/OCP section on this page. The power
