2222 SWITCHMODE POWER SUPPLY

• 230 or 115 VAC primary voltage

• 24 or 15 VDC output voltage

• Double isolation by 3.75 kVAC

• 48 Watt output power,Short circuit-protected

• Thermal protection against overload

• DIN rail mounting on a standard

11-pole relay socket

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 dimensi-ons of the switchmode power supply allow for a high DC output power, even in narrow spaces.

The power supply is based on primary switchmode tech Nology 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. A 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.

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

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