ECM140 Series • High Efficiency Resonant Topology • High Power Density 7.2 W/in3 • 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 EN55022 Level B conducted emissions with leakage currents of 100 μA at 115 VAC or 215 μA 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 Output Power(1) Output Voltage V1 120 W 120 W 120 W 120 W 120 W 120 W 12.0 VDC 15.0 VDC 18.0 VDC 24.0 VDC 28.0 VDC 48.0 VDC Max Output Current V1 10.0 8.0 6.6 5.0 4.2 2.5 Fan Output V2 A A A A A A 12.0 V/0.5 12.0 V/0.5 12.0 V/0.5 12.0 V/0.5 12.0 V/0.5 12.0 V/0.5 Notes: 1.

See drawing on page 13 for component locations. Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of any direct air flow). Temperature Measurements (Ambient ≤ 50 ºC) Component Max Temperature ºC T1 110 °C L3 120 °C Q1 110 °C CR2 110 °C Service Life The estimated service life of the ECM140 is determined by the cooling arrangements and load conditions experienced in the end application. Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of capacitors within the product when installed in the end application. The graph below expresses the estimated lifetime for a given component temperature and assumes continuous operation at this temperature.
