Ultra slim DIN-rail PSUs

30 January 2019 Power Electronics / Power Management

XP Power has announced the DSR range of AC-DC DIN-rail power supplies approved for industrial control systems and information technology equipment applications. These versatile supplies provide reliable power with a 150% peak load capability in a slim-line, DIN-rail mount metal case.

Competitively priced, the DSR’s space-saving design features a width of just 32 mm for 75 W and 120 W models, and 45 mm for 240 W models. For use in industrial and building control applications, specific deployment areas include machine control, process control, factory automation, escalator/travelator/elevator/lift control, building heating/aircon monitoring, control and security systems.

Models DSR75, DSR120 and DSR240 are rated at 75 W, 120 W and 240 W respectively, and feature efficiency figures of 91%, 92% and 94% respectively. The two lower-power models are available with 12, 24 and 48 V outputs, whilst the DSR240 is available with 24 or 48 V outputs. All models operate from 85 to 264 V a.c.

The power supplies’ 150% peak load capability enables startup for electromechanical loads. Ambient temperature rating is -25°C to +70°C for all models, with rated power available up to 50°C or 60°C depending on the model. Volt-free relay contacts facilitate remote monitoring for DC OK. Units can be paralleled for higher requirements or configured to provide N+1 redundancy in critical applications.
