Designed for type BF medical applications, the EXM150 and EXM225 series of 150 and 225W external power supplies have been released by Powerbox. The units are suitable for wall mount, desktop, or floor top placement. Changeable AC cable with ISO10651-2:2004 locking enables compatibility with any type of outlets, while changeable DC cable provides connector adaptability to any load. IP21 protection class enables use in critical medical environments. 

The power supplies utilise the company’s one step conversion topology, where PFC, isolation and regulation are combined in one conversion step, keeping the component count below 120. This contributes to an efficiency of 93% and zero load power of 400,000 hours. The units also feature over temperature protection, regulating output power in the case of over temperature.

The EXM150 and EXM225 series meet electrical safety IEC60601-1 Edition 3, EMC EN55011 class B, class II isolation, and IEC60601-1-11 for home care applications. The units also comply with environmental CEC Level 5, RoHS, REACH and WEEE.
