DIN rail power supplies operate with 3-phase ac inputs

EP&T Magazine   


TDK-LAMBDA DPP120 series ac-dc DIN rail-mount power supplies with outputs rated from 120 to 480-watts that operate off a 3-phase ac line input from 340 to 575Vac. Each series are available with output voltages of 12Vdc and 24Vdc outputs are available in the DPP120 series (rated at 120W) plus 24VDdc and 48Vdc outputs are available in the DPP240 series (rated at 240W) and the DPP480 series (rated at 480W). Units provide bi-phase operation; under a dropped phase condition they will continue to operate with output power derated to 80%.
