TDK Corporation is introducing the TPS3000-24 industrial power supply, delivering up to 3200W output power (24V at 133.3A) in a 2U high package. It operates from a high-voltage, wide-range Delta or Wye 350–528V AC three-phase input, avoiding the requirement for step-down transformers and assisting phase load current balancing. The TPS3000 is suitable for use across many 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. In addition, 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 per cent using front panel potentiometers or an analogue 0–5V DC voltage. Up to eight units can be connected in parallel for higher power and internal ORing FETs allow redundant operation.

The 92.5 per cent efficient unit can operate at full load in ambient temperatures of up to 50degC, and deliver up to 55 per cent load at 70degC. An internal temperature controlled fan is used for cooling to reduce acoustic noise. Case dimensions measure 107 × 84.4 × 324mm (W × H × D), making it suitable for 2U high racking systems, while weight is just 2.7kg.

The power supply has 3kV AC input to output, 2kV AC input to ground and 500V AC output to ground isolation. All models are certified to UL/CSA 60950-1, IEC/EN 60950-1 and carry the CE mark for 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.
