Power Supply Product 3200W 3-phase Delta or Wye AC Input Industrial Power Supply Series Extended with 48V Model

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...


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 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 38.4 – 56.5V and the current limit point by 70-105% using front panel potentiometers or an analog 0-5Vdc 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 50oC, and deliver up to 55% load at 70oC. 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.
