Power Supplies Demonstrate High Efficiency
Possessing a power density of 11 W/in.³, Emerson Network Power’s LPS200-M Series 250 W AC/DC power supplies have a typical full load efficiency of 88%. The 3” × 5” × 1.5” devices offer a universal 90 VAC to 264 VAC input, operation from a 120 VDC to 300 VDC input and an 12 VDC or 24 VDC main output with 16 ms min. hold-up time with 120 VAC input and 250 W output. The ITE-approved supplies present 10.3 A or 5.2 A continuous operation with convection cooling and up to 20.8 A or 10.4 A continuous operation with 30 CFM forced air cooling. The components have an isolated 12 VDC fan output delivering up to 1 A, active power factor correction, ground leakage current of 275 µA max., protection for overvoltage, overtemperature and short-circuit conditions, and a “power fail” signal. The products operate from 0°C to 50°C without derating with cold-start from -20°C and 2.5% per degree derating between 50°C and 70°C.
