XP Power has announced the AJM90 series of 90W single output external AC/DC power supplies. Meeting the US Department of Energy’s new Level VI no load / standby power and active mode efficiency specification, the AJM90 consumes less than 0.21W when no load is connected.
The series has a high average efficiency of typically 89%, measured at 25, 50, 75 and 100% load, and exceeds the power supply energy efficiency requirements stipulated by the Level VI specification. With certification for both the internationally recognised IT and medical safety standards, EN/UL 60950-1 and ANSI/AAMI/EN 60601-1, and offering 2 x MOPP isolation, the unit can aid the end product gaining safety approvals. The class II is approved for medical applications only.
The AJM90 range offers three models with outputs of 12, 18 and 24VDC. Sealed in a slim IP32 environment rated enclosure measuring just 22x140x71mm, the supply is protected against ingress of foreign objects and liquids. With the full output power available up to + 40ºC, the AJM90 can operate in environments from 0 to + 60ºC with output power derating to 50% at 60ºC.
Meeting the Level B EN55011 standard for both radiated and conducted emissions, the unit also meets the stringent immunity requirements of the latest 4th edition medical EMC standards.
