48Vdc 3200W 3-Phase Delta or Wye AC Input Power Supply

June 07, 2017 by Jeff Shepard

TDK Corporation announces the introduction of a 3,200W 48V model to the TPS power supply series. The 2U high product delivers 3200W output power (44V at 133.3A), and operates from a wide range Delta or Wye 350- to 528-Vac three-phase input. The 48V model is designed for use in many applications including test and measurement equipment, semiconductor fabrication, industrial printers and lasers. The high-voltage, three-phase input avoids the requirement for step down transformers and assists phase load current balancing.

The TPS3000-48 is fully featured with isolated AC Fail, DC Good and dropped phase signals, remote on/off, remote sense and a 12V 0.3A standby supply. A PMBusâ„¢ 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 PMBusâ„¢. The output voltage can also be adjusted from 38.4- to 56.5-Vdc and the current limit point by 70% to 105% using front panel potentiometers or an analog 0- to 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 degrees C, and deliver up to 55% load at 70 degrees C. Cooling is provided by an internal temperature controlled fan to reduce acoustical noise. The case measures 107 x 84.4 x 324mm, making it suitable for 2U high racking systems and the weight is just 2.7kg.

The power supply has 3kVac input-to-output, 2kVac input-to-ground and 500Vac output-to-ground isolation with all models certified to UL/CSA 60950-1, IEC/EN 60950-1 and carrying the CE mark for the Low Voltage and RoHS2 Directives. The TPS3000 models comply with EN55032-A conducted and radiated emissions, and meets the IEC 61000-3-2 harmonics, IEC 61000-4 immunity and SEMI F47-0706 standards.
