225 Watt AC-DC supply in a 2in x 4in package

Paul Boughton

XP Power’s EPL225 series of high efficiency open frame AC-DC power supplies are approved for industrial, IT and medical applicationsThe 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 2 x 4inch industry standard ‘1U’ footprint (50.8 x 101.6 x 32.3mm) the series has a convection cooled output power rating of 150 Watts. Output power of up to 225 Watts 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 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 0.5 Watt 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 -20 to + 70˚C and no derating until +50˚C.

The EPL225 range offers a high power density solution and is ideal for space constrained applications that are either convection cooled or have airflow.

The EPL225series is available from Farnell, element14, Digi-Key, approved regional distributors, or direct from XP Power and come with a three year warranty.
