AC/DC power supply CUS250M series

single-outputswitchingwith overcurrent protection

The compact CUS250M series of single output AC-DC power supplies are available with 12V, 15V, 18V, 24V, 28V, 36V and 48V outputs in a compact industry standard 2 x 4 inch footprint and can deliver 250W with convection and conduction cooling. CUS250M can be used in both Class I and Class II (no earth wire) applications and offers efficiencies in excess of 94%. The very low earth leakage (<150uA) and touch current (<10uA for class I, <70uA for class II installations) values make it ideal for medical equipment applications. The standard open frame unit includes an integral metal baseplate and mechanical options include U channel format, U channel with cover and U channel with cover and top mounted cooling fan. Safety certifications include IEC/EN/ES 60601-1 and IEC/EN/UL 62368-1 with UK CA and CE marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions, and meet the IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards. They are designed to meet the requirements of EN60335-1 and IEC61010-1. Typical applications include medical (B and BF type), home healthcare, dental, test and measurement, broadcast, professional audio and industrial equipment. Features Operation in Ambient Temperatures of up to 85°C Medical Certifications (2 x MOPP) Class B Conducted and Radiated EMI with Significant Margins Suitable for Class I and Class II installations Enclosure & Cooling Options Very low earth leakage and touch current Less than 0.5W no load power consumption
