The TPS3000 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 by the PMBus™. The output voltage can also be adjusted from 19.2 – 29 V and the current limit point by 70-105 percent using front panel potentiometers or an analog 0-5 Vdc voltage. Up to eight units can be connected in parallel for higher power and internal ORing FETs allow redundant operation.
The 92 percent efficient power supply can operate at full load in ambient temperatures of up to 50o C, and deliver up to 55% load at 70o C. Cooling is provided by an internal temperature controlled fan to reduce acoustical noise. The supply’s case measures 107 x 84.4 x 324 mm, suiting it for 2U high racking systems and the weight is just 2.7 kg.
The power supply has 3 kVac input to output, 2 kVac input to ground and 500 Vac output to ground isolation with all models certified to UL/CSA 60950-1, IEC/EN 60950-1 and carrying the CE mark for the 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.
