480W DIN-rail power supply can be used in ship’s bridge or deck

Able to meet EMC Class B requirements without external filters, the CP20.245-R2 power supply from PULS is approved to Marine DNV and Marine ABS ATEX, making it suitable for marine and offshore process applications.

The 24V, 20A DIN-rail power supply can be used directly in bridge and deck applications. It is designed for the harsh environmental conditions found at sea and onshore. The power supply has high immunity to transients and voltage peaks as well as a robust aluminium housing. It provides full output power of 480W even with fluctuating ambient temperatures between -40 and +60 degrees C.

An onboard decoupling MOSFET enables a safe 1 + 1 and n + 1 redundancy between multiple power supplies to ensure the availability of all process and safety systems in the event of a fault. The design removes the requirement for an additional external redundancy module, which reduces cost and saving space, added PULS. Special plug-in connectors allow hot-swap replacement of the devices during operation.

The CP20.245-R2 has a high efficiency of 95.2 per cent and 20 per cent power reserve.

For remote status monitoring, two relay contacts for DC-OK and alarm signals are provided. Two additional inputs allow the power supply to be put into an energy-saving standby mode using the remote on / off function and automatic load sharing in parallel operation for greater power output. Parallel operation ensures an optimised temperature balance between the connected power supplies, prolonging the service life of the devices.

The compact CP20.245-R2 has dimensions of just 48 x 124 x 127mm. According to PULS, the low power losses generates less heat in the housing, resulting in reduced clearance and creepage distances.

PULS develops and manufactures power supplies and supplementary units for industrial applications. It was founded by Bernhard Erdl in Munich in 1980.

All PULS products are manufactured in the company’s own facilities in Chomutov, Czech Republic, Suzhou, China, and Drebach, Germany.
