Air cooled, 98% efficient, 45kW ac-dc modular power supply delivers 385Vdc

TDK-Lambda brand TPF45000-385 non-isolated modular ac-dc power supply is developed for use in distributed power architectures (DPA) and DC Microgrids. The 98% highly efficient unit provides a regulated 385Vdc output with a current of up to 117A. Low internal losses enables the use of cooling by fans, avoiding the complexity of water cooling. The industrial grade product is suitable for use in semiconductor test and burn in systems, LED based horticultural lighting and DC Microgrids. Comprising of up to ten 4.5kW modules, product series can deliver up to 45kW of output power in a less than 3U high package, and operates from a wide range Delta or Wye 360 – 528Vac three phase input. Unit can operate at full load in ambient temperatures from -10 to 50oC (-20oC start-up). The enclosure measures 450mm wide (excluding side rack mount flanges) 113mm high and has a depth of 533mm. The weight of the product is 30kg.
