TDK-Lambda Corporation has released the PFE1500FB, a 1500 W AC-DC power module series with an 85 to 305 Vac input range, support for 277 Vac nominal mains and a 38.4 to 57.6 Vdc adjustable output for industrial, lighting and building automation equipment. Its metal baseplate and five-sided case are intended for installations where convection or forced-air cooling is limited, including sealed outdoor enclosures and liquid-cooled systems, while also helping with thermal management and radiated EMI. The series includes a PMBus interface for remote monitoring and programming of output voltage, overvoltage, overcurrent and undervoltage settings, and supports droop-mode current sharing for parallel operation. Rated at 92% typical efficiency at 230 Vac, the modules also provide a 9.5 to 14 V auxiliary output, remote on/off and power-good signaling, and are aimed at test and measurement equipment, semiconductor fabrication, LED displays, lasers and RF power amplifiers.
