4 kW power supply with 3-phase delta or WYE input

TDK-Lambda expands the TPS series with a power supply unit with 48 V, 83.3 A and 4 kW output power. The TPS4000-48 operates from an industrial three-phase input. It can automatically run from 400, 440, or 480 Vac 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, 12 V 0.3 A 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 38.4–58 V and the current limit point by 70-105 percent using front panel potentiometers or an analogue 0–5V dc voltage. To facilitate the easy parallel operation of up to 8 units, for redundant or higher power requirements, an internal ORing FET is included.

Fits in 2U racking systems

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