TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda TPF45000-385 three-phase input, non-isolated 45kW AC-DC power supply. The TPF45000 provides a stable 385Vdc output for large, distributed power systems using isolated DC-DC converters for semiconductor test and burn in, large scale printers and other industrial equipment. With an efficiency of 98%, less internal waste heat is generated, allowing cooling by internal, variable speed fans. Cooling this way avoids the need for expensive and complex water-cooling systems.<\/span><\/p>\n

The TPF45000 can operate from either a Delta or Wye 360 – 528Vac three-phase input and at full load in ambient temperatures from -10\u00b0C to +50\u00b0C (-20\u00b0C start-up). Internally, the power supply comprises up to ten 4.5kW modules, allowing easy configuration of lower power systems. The rack-mount enclosure measures 450mm wide (excluding side rack mount flanges), 113mm high (less than 3U) and 533mm deep, and weighs 30kg.<\/span><\/p>\n

For remote monitoring, DC good, dropped phase and fault alarm, isolated signals are available, along with a remote on\/off capability and a 13 to 15V 0.5A auxiliary output. In addition, the PMBus™ and USB communications interfaces are available to monitor the input voltage, output voltage, output current, internal temperature, status signals and fan status or to inhibit or enable the output voltage.\u00a0<\/span><\/p>\n

The TPF45000 is certified to the IEC\/EN\/UL\/CSA 62368-1 safety standards and has the CE and UKCA marks to 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). The input to ground isolation is 2,000Vac.<\/span><\/p>\n
