Industrial 48V, 83.3A 4kW output power supply

TDK has announced the addition of a 48V, 83.3A 4kW output power supply to TDK-Lambda’s TPS series.

The TPS4000-48 operates from an industrial three-phase input. It can automatically run from 400, 440, or 480Vac nominal delta or WYE inputs, without wiring changes or the need for large, costly step-down transformers. This industrial grade power supply can be used across a vast number of applications including test and measurement equipment, semiconductor fabrication, additive manufacturing, printers, laser cutting and RF power amplifiers.

The series has, as standard, output voltage and current programming, AC fail, DC good and dropped phase warning signals, configurable remote on / off, 12V 0.3A standby voltage and a PMBus interface. Using this interface allows the remote monitoring of the output voltage and current, internal temperature, status signals and fan speed. The PMBus can also program the output voltage, over current limit and the remote on/off. The output voltage is adjustable from 38.4 - 58V and the current limit point by 70-105% using front panel potentiometers or an analogue 0-5Vdc voltage. To facilitate the easy parallel operation of up to 8 units, for redundant or higher power requirements, an internal ORing FET is included.

Excluding the output busbars, the unit measures 107 x 84.4 x 335mm, making it suitable for 2U high racking systems. The TPS4000 has a low weight of just 4kg and a typical efficiency of 92%. The TPS can start up at -40°C, operate at full load in ambient temperatures of -10°C to +50°C, and deliver 55% load at 70°C. The variable speed, temperature-controlled cooling fan reduces acoustic noise and the ingress of contaminants. The power supply has 3kVac input to output, 2kVac input to ground and 500Vdc output to ground isolation.

The three-year warranty TPS is safety certified to IEC/EN/UL 62368-1 and is CE marked to the Low Voltage, EMC and RoHS Directives. The TPS4000 also complies with EN55032-A EMI, SEMI F47-0706, IEC 61000-3-2, IEC 61000-4 and is designed to meet the MIL-STD-461F/G CS101, CS114 (Army Ground), CS115, CS116 immunity standard
