XP Power has announced the ECP150 series of compact open frame 150W AC/DC power supplies. Measuring 101.6x50.8x32mm and with a power density of 14.88W/inch3, the devices comply with UL/EN/IEC60950-1 and UL/EN/IEC60601-1 safety standards for medical and IT equipment. The units have a no load input power of less than 0.5W and a typical efficiency of 91%, helping the end equipment comply with internationally recognised energy efficiency initiatives. Operating from an input of 90 to 264V AC, there are five single output models available, covering nominal outputs of +12, +15, +24, +28 or +48V DC.A 12V/0.5A output is also provided to power an external fan if required. Up to 100W output is achieved by convection cooling, and with only 15CFM of forced cooling the 150W output is available. The unit has a range of operating temperature from -20 to +70°C, which suits most environments. Full power output is available up to +50°C with derating above. No additional heat sinking is required. The units comply with the EN55022 level B standard for conducted noise without using additional filtering components. Over-voltage, overload and short-circuit protection features are included.
