The TDK-Lambda brand TPF45000-385 non-isolated modular AC-DC power supply has been developed by TDK Corporation for use in distributed power architectures (DPA) and DC microgrids. The 98% highly efficient TPF45000 provides a regulated 385 V DC output with a current of up to 117 A, and 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 up to 10 4.5 kW modules, the series can deliver up to 45 kW of output power in a less than 3U high package, and operates from a wide range Delta or Wye 360 V AC to 528 V AC three phase input. The unit can operate at full load in ambient temperatures from -10° C to 50° C (-20° C start-up). The enclosure

The TPF45000 is fully featured with DC Good, dropped phase, over temperature and fault alarm signals, remote on/off and a 13 V to 15 V 0.5 A 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 2 kV AC 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).
