Offering a minimum average efficiency of 93% and a maximum efficiency of 95%, a series of high efficiency open frame AC/DC power supplies has been unveiled by XP Power. The EPL225 series' high efficiency results in a no-load power consumption of less than 0.5W, less heat to dissipate and a cooler running unit, contributing to a more reliable longer-life power supply.

Approved for industrial, IT and medical applications, the series comprises seven single-output models that offer a range of standard output voltages from +12 to +48VDC. A secondary 12VDC/0.5A fan output is provided across the range.

Packaged in an extremely compact low profile 2x4" industry standard ‘1U’ footprint (50.8x101.6x32.3mm) the series has a convection cooled output power rating of 150W which is claimed to be the “best in the industry” for a power supply of this footprint. Output power of up to 225W is available with only 10CFM of forced airflow.

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

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. Featuring low conducted and radiated noise, the units meet the standards EN55011 & EN55022 for Class B conducted and Class A radiated EMI specifications.

The EPL225 series is available from Farnell, element14, Digi-Key, approved regional distributors, or direct from XP Power with a three year warranty.
