Medical-rated 130W AC-DC power supply is smallest available

November 25, 2015 // By Graham Prophet
XP Power's high efficiency ECP130 series of miniature open-frame AC-DC power supplies has safety approvals for the ITE and medical equipment markets.

The units deliver the full 130W output with only 10 CFM of forced air cooling and are also able to provide a convection-cooled rating of 100W, eliminating the need for cooling fans. Seven single-output models deliver 12,15, 18, 24, 28 36 or 48 VDC, each of which accepts an input voltage of between 85 and 264 VAC and has dual input fuse protection on line and neutral.

The series has footprint measuring 50.8 x 76.2 mm and a low profile of 28.0 mm. Taking up 25% less board space than the current 2 x 4-in. industry standard, the range delivers a high power density of up to 19.7 W/in ² with typical efficiency figures of 95%, and a no-load consumption of less than 0.5W.

The modules have been certified to meet ITE 60950-1 and 3rd edition medical approvals including IEC60601-1 and ANSI/AMMI ES60601-1. They have low-leakage current and provide two means of patient protection (MOPP) isolation between input and output and one means of operator protection (MOOP) between output and ground.

All units in the ECP130 series of AC-DC supplies have a wide operating temperature range, from -40 to +70C, with no derating until 50C, and meet Class B conducted and Class A radiated limits of EN55011 and EN55022, removing the need for additional external EMI filtering.

The ECP130 series is available from Farnell, element14, Digi-Key, regional distributors, or direct from XP Power and come with a 3 year warranty.
