Power supply features a fully regulated, wide-range, adjustable output

Stocked by Digi-Key, TDK has introduced the TDK-Lambda brand TPS3000-24 power supply. Delivering up to 3,200W output power (24V at 133.3A) in a 2U-high package, the TPS will operate from a wide-range, Delta or Wye 350, 528VAC three-phase input. This industrial power supply is ideal for use in many applications including test and measurement equipment, semiconductor fabrication, printers, lasers, and RF power amplifiers. The high-voltage, three-phase input avoids the requirement for step-down transformers and assists phase load current balancing. The device is fully featured with isolated AC fail, DC good, dropped phase signals, remote on/off, remote sense, and a 12V 0.3A standby supply. A PMBus communications interface allows remote monitoring of the output voltage, output current, internal temperature, status signals, and fan speed. In addition, the output voltage, over-current limit, and the remote on/off can be programmed by the PMBus. The output voltage can also be adjusted from 19.2V to 29V, and the current limit point by 70% to 105%, using front-panel potentiometers or an analog, 0VDC to 5VDC voltage. Up to eight units can be connected in parallel for higher power, and internal ORing FETs allow redundant operation. The 92% efficient unit can operate at full load in ambient temperatures of up to 50C and deliver up to 55% load at 70C. Cooling is provided by an internal temperature-controlled fan to reduce acoustical noise. The case measures 107mm x 84.4mm x 324mm, making it suitable for 2U-high racking systems, and the weight is just 2.7kg.
