XP Power announces 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 12 V_DC to 48 V_DC. A secondary 12 V_DC / 0.5 A fan output is provided across the range. Packaged in an extremely compact low profile 2" x 4" industry-standard '1U' footprint (50.8 mm x 101.6 mm x 32.3 mm), the series has a convection cooled output power rating of 150 W which is believed to be "best in the industry" for a power supply of this footprint. Output power of up to 225 W is available with only 10 CFM of forced airflow.

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 latter contributing to a more reliable longer-life power supply. In addition, the units' "green" attributes include a no-load power consumption of less than 0.5 W 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/AAMI/ 60601-1 and IEC/EN60601-1 3rd edition. With low conducted and radiated noise, the units meet the standards EN 55011 and EN 55022 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 -20°C to 70°C and no derating until 50°C.
