TDK Corporation announces the introduction of the TDK-Lambda brand TPF45000-385 non-isolated modular AC-DC power supply. Developed for use in distributed power architectures (DPA) and DC Microgrids, the 98% highly efficient TPF45000 provides a regulated 385Vdc output with a current of up to 117A. Low internal losses enable the use of cooling by fans, avoiding the complexity of water cooling. This 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, the 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. The 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.
The TPF45000 is fully featured with DC Good, dropped phase, over-temperature and fault alarm signals, remote on/off, and a 13 to 15V 0.5A auxiliary output. PMBus and USB communications interfaces allow remote monitoring of the input voltage, output voltage, output current, internal temperature, status signals, and fan. In addition, the remote on/off can be programmed by the PMBus.
The power supply has 2kVac primary to ground isolation, is certified to IEC/EN/UL/CSA 62368-1, and carries the CE mark for the Low Voltage, EMC and RoHS Directives. The TPF45000 also complies with EN55032-A (conducted and radiated emissions), SEMI F47-0706 (line dips), and IEC 61000-4 (immunity).
