XP Power launches ultra compact 150W ac/dc power supply
XP Power has announced the launch of the ECP150 series of compact open frame 150W ac/dc power supplies. Measuring 101.6 x 50.8 x 32mm and with a power density of 14.88W per cubic inch, the series 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%.
Operating from a universal input of 90-264Vac, there are five single output models available within the range, covering the nominal outputs of +12, +15, +24, +28 or +48Vdc. A 12V/0.5A output is also provided to power an external fan if required. According to XP, up to 100W output is achieved by convection cooling alone, and with only 15 CFM of forced cooling the full 150W output is available.
The ECP150 has an operating temperature range from -20 to 70°C. Full power output is available up to 50°C with derating above. No additional heat sinking is required.
The units are said to comply with the EN55022 level B standard for conducted noise without the need for additional filtering components. Overvoltage, overload and short circuit protection features are included as standard across the whole range.
