TDK-LAMBDA TPS4000-24 power supply delivers up to 4080W output power (24V at 170A) in a 2U high package and operates from a wide range Delta or Wye 350 – 528Vac three phase input. Industrial unit is suitable for use in many applications including test and measurement equipment, semiconductor fabrication, additive manufacturing, printers, lasers and RF power amplifiers. Product’s high voltage, three-phase input avoids the requirement for costly step down transformers and assists phase load current balancing. Device is fully featured with isolated ac Fail, dc Good and dropped phase signals, remote on/off, remote sense and a 12V 0.3A standby supply.  A PMBus communications interface allows remote monitoring of the output voltage, output current, internal temperature, status signals and fan speed.
