Applications

• General 24 or 15vDC 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.

Features

• 230 or 115VAC primary voltage
• 24 or 15VDC 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

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. A 1A 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 2.5A. A green LED on the front of the module indicates an active primary voltage.

Mounting:

The 2222 is mounted via the 11-pole socket mounting bracket, which can be fitted directly on the bottom plate, or to a DIN Rail. A front panel mounting frame can be used for enclosure mounting and a retention clip is available for securing the unit for installations with high vibrations. Note: To achieve maximum cooling, mount in a vertical position with a minimum of 10mm between neighbouring units.

Input:

Standard supply voltages in accordance to the specified input voltages (115 or 230vAC) ±10%. Galvanic isolation is ensured by the double insulated safety transformer.

Output:

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