1. Safety instructions

• Switch main power off and wait 5 minutes before making any connection or

disconnection on the device. Danger of serious injury or damage!

• To guarantee sufficient convection cooling, please keep a distance of 50 mm [1.97

in] above and below the device as well as a lateral distance of 20 mm [0.79 in] to other units.

• Please note, that the enclosure of the device can become very hot depending on

the ambient temperature and load of the power supply. Risk of burns!

• Only plug in and unplug connectors when power is turned off!

• Do not introduce any objects into the unit!

• Dangerous voltage present for at least 5 minutes after disconnecting all sources of power.

• To protect against access to live parts the power supply unit (PSU) must be installed

in a protective enclosure.

2. Device description (Fig. 1)

(1) Input & Output terminal block connector

(2) DC voltage adjustment potentiometer

(3) DC OK control LED (green)

(4) 35mm DIN rail mounting (DIN rail sold separately)

3. Mounting (Fig. 2)

The power supply unit can be mounted on 35 mm DIN rails in accordance with EN60715.

The device should be installed with input terminal blocks on the bottom.

Each device is delivered ready to install.

Snap on the DIN rail as shown in Fig. 2:

1. Pull the unit's DIN rail latch OUT.

2. Tilt the unit slightly upwards, hook the top end onto the DIN rail.

3. Position the bottom front end against the DIN rail.

4. Push the unit's DIN rail latch IN to lock.

4. Dismounting (Fig. 3)

To uninstall:

1. Pull the unit's DIN rail latch OUT.

2. Tilt the bottom part of the unit out.

3. Push the unit up and pull out from the DIN rail.

5. Connection

The terminal block connectors allow easy and fast wiring. A plastic cover provides the necessary

isolation of the electric connection.

You can use flexible (stranded wire) or solid wire with cross section 0.32-2.1 mm² (AWG 22-14) and

torque of 0.79Nm (7.0lb in). To secure reliable and shock proof connections, the stripping length

should be 7 mm [0.28 in].

In accordance to EN 60950 / UL 60950, flexible wire require ferrules.

Use appropriate copper wire that is designed to sustain operating temperature of at least 75°C

[167°F] or more to fulfilll UL requirements.

For stranded wires it is recommended to use suitable lug to crimp wires (see Fig. 4).

5.1. Input connection (Fig. 1, Fig. 5)

Use L, N and GND connections of input terminal connector (see Fig. 1 (1)) to establish the 100-240

VAC connection.

For 3-phase systems just use two phases for the connection to L and N. Need to connect GND and

provide an isolation facility for all poles. The unit is protected with internal fuse (not replaceable)

at L pin and it has been tested and approved on 20A (UL) and 16A (IEC) branch circuits without

additional protection device. An external protection device is only required if the supplying branch

L2 (N)

has an ampacity greater than above. Thus, if an external protective device is necessary, or, utilized, a

minimum value of 13A B- or 6A C- characteristic breaker should be used.

The internal fuse must not be replaced by the user. In case of internal

defect, the unit must be discarded or returned if still under warranty

5.2. Output connection (Fig. 1 (2))

Use the "+" and "-" screw connections to establish the 12 VDC connection. The output provides 12

VDC. The output voltage can be adjusted from 11 to 14 VDC by the potentiometer.

The green LED DC OK displays correct function of the output (Fig. 1 (3)).

The device has a short circuit and overload protection and an overvoltage protection limited to 17.6

VDC.

5.3. Output characteristic curve

The device functions normal under operating line and load conditions. In the event of a short

circuit or over load the output voltage and current collapses (IO/L or IS/C is > Isurge (150%)). The sec-

ondary voltage is reduced and cycles on and off until short circuit or overload on the

secondary side has been removed.

5.4. Thermal behavior (Fig. 6)

In the case of ambient temperatures above +50°C [122°F], the output capacity has to be reduced as

shown in Figure 6. If the output capacity is not reduced when TAmb > 50°C [122°F] device will switch

into thermal protection mode. The device will cycle output on and off to maintain internal power

dissipation and will recover when ambient temperature is lowered or load is reduced as far as nec-

essary to keep device in a normal operating mode.
