New 95% efficient 225W AC/DC supply in a compact package

XP Power has introduced the EPL225 series of high-efficiency open-frame AC/DC power supplies approved for industrial, IT and medical applications. The series comprises seven single-output models that offer a range of standard output voltages from +12VDC to +48VDC. A secondary 12VDC / 0.5A fan output is provided across the range. Packaged in an extremely compact low profile 50.8 x 101.6 x 32.3 mm industry-standard ‘1U’ footprint the series has a convection cooled output power rating of 150W which is believed to be 'best in the industry' for a power supply of this footprint. Output power of up to 225W is available with only 10 CFM of forced airflow, says the company. The EPL225 series offers a minimum average efficiency of 93% and a maximum efficiency of 95% resulting in less heat to dissipate and a cooler running unit, the later contributing to a more reliable longer-life power supply. In addition, the units 'green' attributes include a no-load power consumption of less than 0.5W enabling compliance with the latest environmental goals and legislation. The series complies with the universal safety standard EN 60950-1 for IT equipment in addition to the medical safety standards ANSI/AAME/ 60601-1 and IEC/EN60601-1 3rd edition. With low conducted and radiated noise the units meet the standards EN55011 & EN55022 for Class B conducted and Class A radiated EMI specifications. The EPL225 suits use in a broad range of operating environments with an extended temperature range from -20C to + 70C and no derating until +50C. The EPL225 range offers a high power density solution for space-constrained applications that are either convection cooled or have airflow.
