TDK adds a 48V 480W output model to its economically priced DRB series of 15 to 480W DIN rail mount power supplies. The product’s narrow 84mm width provides additional space for other DIN rail modules, or the use of a smaller enclosure.

Applications for the DRB480-48-1 DIN rail power supply include factory automation, industrial process control, semiconductor fabrication, communications and test and measurement equipment. The DRB480 rugged metal case has a depth of 124mm, a height of 125mm. The power supply operates from a wide range 90 – 264Vac input enabling worldwide use. The DRB480-48-1 has a 48V 10A output and features a DC OK relay contact in addition to an LED indicator. The output can be adjusted from 48 – 52.8V to compensate for series blocking diodes or MOSFETs in redundant configurations. Input to output isolation is 3,000Vac, input to ground 1,500Vac and output to ground is 500Vac. The DRB480 is convection cooled and rated for operation in -20 to +70ºC ambient temperatures (cold start at -40ºC), with linear derating above 50ºC to 62.5% load at 70ºC. A high efficiency of up to 92% reduces internal heating of the electrolytic capacitors, providing a field life in excess of 10 years with 24 hours a day operation at 75% load, 230Vac input and 40ºC ambient.
