Digital power supply

September 10, 2008

Lambda has introduced a new range of digitally controlled modules to its innovative NV-Power family of configurable AC-DC power supplies enabling increased power output of up to 1450W peak rating for 10 seconds. The new modules enable Lambda to satisfy the demand for low-profile configurable power solutions from 350W to above 1,000W for broadcast, instrumentation, medical equipment, ATE, automation, routers, servers and security networks.

NV-Power employs an 8-bit microcontroller to handle housekeeping routines, replacing the array of comparators, op amps and other discrete components used in less integrated designs. The NV-350 series provides up to 350W of output power with <180Vac mains, and up to 660W continuous (740W peak for 10 seconds) with >180Vac mains. Up to six user-selectable outputs can be provided in a 1.6 x 3.75 x 10.8-inch package. The NV-700 series provides up to 700W of output power with <150Vac mains, and up to 1150W continuous (1450W peak for 10 seconds) with >150Vac mains. Up to eight user-selectable outputs can be provided in a 1.6 x 4.92 x 10.8-inch package.

Lambda's Multi Resonant Topology (MRT) and other EMC improving design features have resulted in meeting Curve B EMC performance with earth leakage current less than 300uA at 264Vac, 63Hz (meeting the requirement for IEC/EN/UL60601-1).
