Engineering Data

Output Load De-rating VS Surrounding Air Temperature

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 will run into Over Temperature

Protection. When activated, power supply will

latch off, until the surrounding air temperature

is lowered or the load is reduced as far as

necessary to keep the device in working

condition, and require removal/re-application

of input AC voltage in order to restart.

3. In order for the device to function in the

manner intended, it is also necessary to keep

a safety distance of 80mm (3.14 inch) above

and below the device as well as a lateral

distance of 25mm (0.98 inch) to other units

while the device is in operation.

Depending 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 contact

[email protected] for more details.

Output Load De-rating VS Input Voltage

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



No output power de-rating across the entire

input voltage range

Dismounting

Fig. 2.1 Mounting

Snap on the DIN rail as shown in Fig. 2.1:

1. Tilt the unit slightly upwards and put it onto the DIN rail.

2. Push downwards until stopped.

3. Press against the bottom front side for locking.

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 slide the power supply unit (PSU) in

the opposite direction, release the latch and pull out the power

supply unit (PSU) from the rail.

Safety Instructions

– ALWAYS switch mains of input power OFF before connecting and

disconnecting the input voltage to the device. If mains are not turned OFF,

there is risk of explosion / severe damage.

– To guarantee sufficient convection cooling, keep a distance of 80mm

(3.14 inch) above and below the device as well as a lateral distance of

25mm (0.98 inch) to other units.

– Note that the enclosure of the device can become very hot depending on

the surrounding air temperature and output load connected to the device.

Risk of burns!

– The main power must be turned off before connecting or disconnecting the

wires to the terminals!

– DO NOT insert any objects into the device.

– Dangerous voltages present for at least 5 minutes after disconnecting all

sources of power.

– 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.

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 final steady state 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 final steady state set value.

Hold-up Time

Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value.

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 0% to

100% of its rated current.
