TDK Corporation has added the TDK-Lambda brand TPS4000-12 power supply, extending the existing 3kW to 4kW rated TPS series. Supplying up to 2040W output power (12V at 170A) in a 2U high package, the TPS4000 series operates from a wide range Delta or Wye 350-528VAC three-phase input. These industrial power supplies are ideal for many applications, including test and measurement equipment, semiconductor fabrication, additive manufacturing, printers, lasers and RF power amplifiers. The high voltage, three-phase input avoids the requirement for costly step-down transformers and assists phase load current balancing.
The series 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 permits remote monitoring of the output voltage, output current, internal temperature, status signals and fan speed. Also, 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 9.6V to 14.1V 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 device can work at full load in ambient temperatures of up to 50C and deliver up to 55% load at 70C. An internal temperature-controlled fan provides cooling to reduce acoustic noise. The case measures 107mm x 84.4mm x 335mm, making it suitable for 2U high-racking systems. The weight of the product is just 4kg.
The power supply has 3kVAC input to output, 2kVAC input to ground and 500VDC output to ground isolation. All TPS models are certified to IEC/EN/UL/CSA 62368-1 and carry the CE and UKCA marks for the Low Voltage, EMC and RoHS Directives. The TPS4000 also complies with EN55032-A (conducted and radiated emissions), SEMI F47-0706 (line dips), IEC 61000-3-2 (harmonics), IEC 61000-4 (immunity), and is designed to meet the MIL-STD-461F/G CS101, CS114 (Army Ground), CS115, and CS116 immunity standards.
