PULS Power offers availability of its new 24V, 20A DIN-Rail power supply CP20.245-R2, developed for on and offshore use in the marine and offshore process industries. The marine-compliant power supply meets the high demands of EMC class B with no additional external filters and can be utilised directly in bridge and deck applications.
The device has optimal electronic and mechanical design for the severe environmental conditions found at sea and onshore. The power supply is characterised by its high immunity to transients and voltage peaks and its robust aluminium housing. The device offers full output power of 480W even with fluctuating ambient temperatures between -40C and + 60C. The extensive approval package comprises Marine DNV, Marine ABS and ATEX, among others.
High system reliability is ensured thanks to an integrated decoupling feature, which makes the device unique. An onboard decoupling mosfet facilitates a safe 1 + 1 and n + 1 redundancy between multiple power supplies. This assures the availability of all process and safety systems as the result of a fault. The innovative design eliminates the necessity for an extra external redundancy module, decreasing cost and saving space. Special plug-in connectors enable hot-swap replacement of the devices during operation, utilising the sequence described in the datasheet.
All CP20 versions share the same compact housing with dimensions of 48mm x 124mm x 127mm (WxHxD). This is achievable by particularly high efficiency of 95.2%. As a result of the low power losses, less heat is produced in the housing and the clearance and creepage distances can be decreased.
Marco van der Linden, UK country manager for PULS Power, comments: “The market for instrumentation, control and SMART systems in marine and offshore applications is growing. Our latest version of the proven CP20 DIN-Rail power supplies not only meets all relevant standards but offers a compact, reliable and simple to install solution. The ability to be connected for parallel redundancy with no additional components increases system reliability while saving space and cost.”
