A new series of ac-dc DIN-rail-mount 120 to 480-W power supplies operate off a three-phase ac line input from 340 to 575 Vac.
A new series of ac-dc DIN-rail-mount 120 to 480-W power supplies operate off a three-phase ac line input from 340 to 575 Vac.Available output voltages include 12 and 24 Vdc for the DPP120 Series (rated at 120W), and 24 and 48 Vdc for the DPP240 Series (rated at 240 W) and the DPP480 Series (rated at 480 W). The supplies feature a biphase operation: under a dropped phase condition they will continue to operate with output power derated to 80%. All models have power-factor correction and output voltages can be adjusted to allow for voltage drop in cables. When used individually, load regulation is ±1%, and ±5% when two supplies are connected in parallel for higher power applications.The 24-V model includes a voltage-monitoring (dc good) relay rated at 0.3 A that closes when output voltage is above 17.6 V to 19.4 Vdc.Additional features include overcurrent, overvoltage, and overtemperature protection with auto recovery. Operating temperature range is from –25 to 71°C.TDK-Lambda Americas, 3055 Del Sol Blvd., San Diego, CA 92154, (800) 526-2324, www.us.tdk-lambda.com/lp/products/dpp-series.htm
