TDK-Lambda: 48V 4kW industrial power supplyERT

TDK Corporation announces 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 is ideal for use in a vast number of applications including test and measurement equipment, semiconductor fabrication, additive manufacturing, printers, laser cutting and RF power amplifiers.

The TPS4000 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.

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.

The TPS4000 has 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 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.
