aPPLICaTIONS:

General 24 or 15 VDC supply for equipment that requires a stabilised DC voltage .
Separation of circuits in safety installations according to the PELV/SELV norm .
Two units can be connected in series to achieve a plus / minus supply or a higher
output voltage . The small mechanical dimensions of the switchmode power
supply allow for a high DC output power, even in narrow spaces .

TECHNICaL CHaRaCTERISTICS:

The power supply is based on primary switchmode technology to achieve a high
efficiency . Galvanic isolation between the primary and the secondary voltage is
achieved through the double-isolated safety transformer . A thermal fuse protects
the input circuit when the internal temperature exceeds 100°C .
An 1 A fuse on the input protects the switchmode power supply against a short
overload . The DC output is protected against a short circuit by an electronic
current limiter that activates at an output current of 2 .5 A . A green LED on the
front of the module indicates an active primary voltage .

MOuNTING:

To achieve maximum cooling of the module, mounting in a vertical position at a
distance of minimum 10 mm between neighbouring units is recommended .

INPuT:

AC power supply according to the specifications .

OuTPuT:

DC voltage of 24 or 15 V . An internally mounted potentiometer allows for a ±5%
adjustment of the output voltage .
