TDK has launched a 24V, three phase digital AC-DC industrial power supply that delivers over 4kW for test and measurement equipment, semiconductor fabrication, additive manufacturing, printers, laser cutting and RF power amplifiers.
The TDK-Lambda TPS4000-24 industrial power supply is rated at up to 4,080W at 24V and operates automatically from 400, 440, and 480Vac nominal delta or WYE (3 live + neutal) inputs, without wiring changes or the need for large, costly step-down transformers.
The TPS4000 includes output voltage and current programming, warning signals, configurable remote on/off, a 12V 0.3A standby voltage and a PMBus interface. Using this communications function allows remote monitoring of the output voltage, output current, internal temperature, status signals and fan speed. The output voltage, over current limit and the remote on/off are programmable via the PMBus.
The output voltage is adjustable from 19.2 to 28.5V and the current limit point by 70-105 percent using front panel potentiometers or an analogue 0-5Vdc voltage. An internal ORing FET simplifies the parallel operation of up to 8 units for redundant or higher power requirements.
With 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% load at 70°C. Cooling is provided by a variable speed, temperature controlled fan to reduce acoustical noise and the ingress of containments. The power supply has 3kVac input to output, 2kVac input to ground and 500Vdc output to ground isolation.
Excluding the output busbars, the unit measures 107 x 84.4 x 335mm, making it suitable for 2U high racking systems, and weighs 4kg.
The three year warranty TPS is safety certified to IEC/EN/UL 60950-1 (62368-1 pending) 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.
