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
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.
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
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
