The TPS4000-24 power supply delivers up to 4,080 W of output power (24 V at 170 A) in a 2U high package. It operates from a wide-range Delta or Wye 350–528 Vac three-phase input. The high-voltage input avoids the requirement for step-down transformers and assists phase load current balancing. It is fully featured with isolated ac fail, dc good and dropped-phase signals, remote on/off, remote sense and a 12-V 0.3-A standby supply. A PMBus communications interface allows remote monitoring of the output voltage, output current, internal temperature, status signals and fan speed. In addition, the output voltage, overcurrent limit and the remote on/off can be programmed by the PMBus.
