3.2kW power supply targets test systems with 3-phase input
The TPS3000-24It operates from a high voltage, wide range Delta or Wye 350 – 528Vac three phase input, avoiding the requirement for step down transformers and assisting phase load current balancing for test and measurement equipment as well as lasers, RF power amplifiers and semiconductor test systems.
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% using front panel potentiometers or an analogue 0-5Vdc voltage. Up to eight units can be connected in parallel for higher power and internal ORing FETs allow redundant operation.
The 92.5% efficient unit can operate at full load in ambient temperatures of up to 50°C, and deliver up to 55% load at 70°C. An internal temperature controlled fan is used for cooling to reduce acoustic noise. Case dimensions measure 107 x 84.4 x 324mm (W x H x D), making it suitable for 2U high racking systems, while weight is 2.7kg.
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 TPS3000-24 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.
