Industrial power supply

The TDR-960 Series industrial power supply is a DIN-railtype unit that features a 340 to 550-Vac three-phasewide input range. The supply can capture two phases out of three and still operate by derating power during the phase failure status. The unit’s 110-mm width saves space on the rail and makes it 40.2% smaller than its predecessor, yet it has 2.5 to 3% higher efficiency.

The 94.5% high-efficiency supply can be full-load operated with free-air convection cooling from –30 to 50°C (or up to 70°C by suitable power derating). The unit’s additional features include built-in active PFC function; dc OK relay contactalarm signal output, front-panel LED indicator; front-panel dc-voltage adjustment; parallel function; and short-circuit, overload, overvoltage, and overtemperature protection.
