The TPS4000-12 power supply extends the TPS series of 350 – 528Vac three-phase input power supplies to include a 12V output in addition to the existing 24V and 48V models.

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 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 the remote on/off can be programmed using the PMBus.

Up to eight units can be connected in parallel for higher power and internal ORing FETs allow redundant operation. The TPS4000-12 can operate at full load in ambient temperatures of up to 50oC and deliver up to 55% load at 70oC. Cooling is provided by an internal temperature-controlled fan to reduce acoustical noise. The case measures 107 x 84.4 x 335mm, making it suitable for 2U high racking systems. The weight of the product is 4kg.

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.
