3.2 kW industrial PSU: high voltage, wide range Delta or Wye 3-phase input
The TPS3000 is intended for use across applications including test and measurement equipment, printers, lasers, RF power amplifiers and semiconductor fabrication. Fully featured with isolated AC Fail, DC Good and dropped phase signals, the TPS3000 has remote on/off, remote sense and a 12V 0.3A standby supply. Its PMBus communications interface allows remote monitoring of output voltage, output current, internal temperature, status signals and fan speed. Output voltage, over current limit and remote on/off can be programmed via the PMBus. Output voltage can also be adjusted from 19.2 – 29V and current limit point by 70-105% using front panel potentiometers or an analogue 0-5 VDC voltage. Up to eight units can be connected in parallel for higher power and internal ORing FETs allow redundant operation.
The 92.5% efficient unit can operate at full load in ambient temperatures of up to 50°C, and deliver up to 55% load at 70°C. An internal temperature controlled fan is used for cooling to reduce acoustic noise. Case dimensions measure 107 x 84.4 x 324mm (W x H x D), making it suitable for 2U high racking systems, while weight is 2.7kg.
