TDK Corporation announces the introduction of the TDK-Lambda brand TPS3000-24 power supply. Delivering up to 3,200 W output power (24 V at 133.3 A) in a 2-U-high package, the TPS will operate from a wide-range, Delta or Wye 350, 528 V_AC 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 TPS3000 is fully featured with isolated AC fail, DC good, dropped phase signals, remote on/off, remote sense, and a 12 V 0.3 A 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 19.2 V to 29 V, and the current limit point by 70% to 105%, using front-panel potentiometers or an analog, 0 V_DC to 5 V_DC 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 50°C and deliver up to 55% load at 70°C. Cooling is provided by an internal temperature-controlled fan to reduce acoustical noise. The case measures 107 mm x 84.4 mm x 324 mm, making it suitable for 2-U-high racking systems, and the weight is just 2.7 kg.

The power supply has 3 kV_AC input-to-output, 2 kV_AC input-to-ground and 500 V_AC 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 TPS3000-24 complies with EN55022-A conducted and radiated emissions and meets the IEC 61000-3-2 harmonics, IEC 61000-4 immunity, and SEMI F47-0706 standards.
