Approved for Class I and Class II applications, the ECM140 range of single output AC/DC, 148 Watt power supplies feature high power density in an industry standard 3 x 5" (76.2mm x 127mm) footprint. The 1.3" (33mm) high, 1U compatible high-density power supplies meet EN55022 Level B conducted emissions with leakage currents of 100μA at 115VAC or 215μA at 230VAC. Making these switchers ideal for industrial, IT and medical applications. The ECM140 series has single output versions from 12V to 48VDC, adjustable by ±5%. All models include an additional +12V / 0.5A fan output. They are dual-fused for compliance with IEC60601-1 and efficiency is 88% typical, so minimal excess heat is generated. The ECM140 require only 10 CFM of cooling to deliver a full 148 Watt of power up to 60°C and operates at up to 70°C with derating. The units also supply 120 Watt when convection-cooled up to 50°C with operation to 70°C with derating. Comprehensive overvoltage, overload and short circuit protection is built in.
