TDK CORP. TDK-Lambda TPS4000-12 power supply delivers up to 2040W output power (12V at 170A) in a 2U high package, and operates from a wide range Delta or Wye 350 – 528Vac three phase input. The industrial units are suitable for use in many applications including test and measurement equipment, semiconductor fabrication, additive manufacturing, printers, lasers and RF power amplifiers. The high voltage, three-phase input avoids the requirement for costly step-down transformers and assists phase load current balancing. Product series 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. In addition, the output voltage, over current limit and the remote on/off can be programmed by the PMBus. The output voltage can also be adjusted from 9.6 to 14.1V and the current limit point by 70-105% using front panel potentiometers or an analog 0-5Vdc voltage.
