ECM140 Series High Efficiency Resonant Topology 3 High Power Density 7.2 W/in Convection & Force-cooled Ratings Class I & Class II Installations Industry Standard 3.0 x 5.0 x 1.30 Format 12 V Fan Output as Standard 5 V Standby Option Remote Sense as Standard IT, Industrial & Medical Safety Approvals Remote On/Off & Power Good Signals Option Approved for Class I and Class II applications, the ECM140 range of single output AC-DC, 148 W power supplies feature high power density in an industry standard 3 x 5 (76.2 mm x 127.0 mm) footprint. The 1.30 (33.0 mm) high, 1U compatible high-density power supplies meet EN55032 Level B conducted emissions with leakage currents of 100 A at 115 VAC or 215 A at 230 VAC. Making these switchers ideal for industrial, IT and medical applications. The ECM140 series has single output versions from 12 V to 48 VDC, adjustable by 5%. All models include an additional +12V / 0.5 A 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 W of power up to +60 C and operates at up to +70 C with derating. The units also supply 120 W when convection-cooled up to +50 C with operation to +70 C with derating. Comprehensive overvoltage, overload and short circuit protection is built in. Optional A units offer a +5 V / 0.5 A standby rail, an open collector Power OK signal and Remote On/Off function. xppower.com Models and Ratings - Convection-cooled Max Fan Output Standby Supply (1) (2,3) Output Power Output Voltage V1 Model Number V3 (optional) Output Current V1 V2 120 W 12.0 VDC 10.0 A 12.0 V/0.5 A 5.0 V/0.5 A ECM140US12 120 W 15.0 VDC 8.0 A 12.0 V/0.5 A 5.0 V/0.5 A ECM140US15 120 W 18.0 VDC 6.6 A 12.0 V/0.5 A 5.0 V/0.5 A ECM140US18 120 W 24.0 VDC 5.0 A 12.0 V/0.5 A 5.0 V/0.5 A ECM140US24 120 W 28.0 VDC 4.2 A 12.0 V/0.5 A 5.0 V/0.5 A ECM140US28 120 W 48.0 VDC 2.5 A 12.0 V/0.5 A 5.0 V/0.5 A ECM140US48 Notes: 1.
