Mil-spec power supply for industrial, military, and test and measurement applications offered by TDK Lambda
SAN DIEGO – TDK-Lambda Americas Inc. in San Diego is introducing the TPS4000-12 mil-spec power supply for test and measurement equipment, semiconductor fabrication, additive manufacturing, printers, lasers, and RF power amplifiers.
The power electronics device offers as much as 2040 Watts output power (12 volts at 170 amps) in a 2U high package, and operates from a wide range Delta or Wye 350 to 528-volt-AC three phase input.
The TPS4000 series offers isolated AC fail, DC good and dropped phase signals, remote on/off, remote sense, and a 12 volts 0.3 amps standby supply.
A PMBus communications interface enables 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 power supply output voltage can be adjusted from 9.6 to 14.1 volts and the current limit point by 70 to 105 percent using front panel potentiometers or an analog 0 to 5 volts DC voltage. Users can connect as many as eight units in parallel for high power, and internal ORing FETs allow redundant operation.
The TPS4000-12 can operate at full load in ambient temperatures as high as 50 degrees Celsius and deliver as much as 55 percent load at 70 C. Cooling is provided by an internal temperature controlled fan to reduce acoustical noise. The case measures 107 by 84.4 by 335 millimeters, making it suitable for 2U-high racking systems. The weight of the product is 4 kilograms.
The power supply has 3k volts AC input to output, 2k volts AC input to ground, and 500 volts DC 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 mil-spec 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.
