TDK Corporation announces the addition of a 3,200W, 48V at 66.7A rated model to its TPS3000 series of industrial power supplies. Capable of operating from a 350 - 528Vac three phase input in a Delta or Wye configuration, the TPS3000-48 avoids the need for step down transformers that traditional 208/230Vac input power supplies require. In addition, phase current balancing is simplified. The TPS3000 series is ideal for use in many applications, including test equipment, digital printers, laser cutting, RF power amplifiers and semiconductor fabrication equipment.
The TPS3000 has an impressive range of programming, monitoring and control signals. These include isolated AC Fail, DC Good and dropped-phase signals, remote on/off and remote sense functions and a 12V 0.3A standby supply. The 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 remote on/off can be programmed via the PMBus™. Alternatively the output voltage can also be adjusted from 38.4 – 56.5V and current limit point by 70-105% using the front panel potentiometers or an analogue 0-5Vdc voltage. For higher power applications, up to eight units can be connected in a parallel. Redundant operation is also possible with the TPS3000 internal ORing FETs.
With an efficiency of 92.5%, the TPS3000-48 delivers full power in ambient temperatures of between -40 and +50°C, derating linearly to 55% load at +70°C. Acoustic noise is minimised and fan life extended with the use of a temperature controlled, variable speed internal fan. Measuring 107 x 84.4 x 324mm (W x H x D), the TPS models can be mounted in 2U racks.
The power supply has 3kVac input to output, 2kVac input to ground and 500Vac 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 series 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
