Mean Well has introduced a new series of Din Rails with a single phase wide input range the WDR series. The WDR-120 series is a 120-watt AC/DC slim line DIN rail power supply with very high efficiency of up to 92%.
This WDR series is equipped with 180 to 550Vac single phase wide input range, able to operate with single phase 230Vac input or utilising one phase from the 330~550Vac three-phase power system, which greatly increases the flexibility of the power supply.
With up-to-date circuit design the WDR-120 series can provide 120 watts continuously up to 60°c by only free air convection, or operate up to 70°c ambient temperature with power derating.
The slim design of only 40mm width makes it 30.58% smaller in size compare to its predecessor the DRH-120 series a 120 watt 340~550Vac/dc single phase. With a wider input range, the WDR-120 also has 6% higher efficiency than equivalent models. Other standard functions include DC OK relay contact, power on LED indicator, as well as protection for short-circuit, overload, over voltage, and over temperature.
The WDR-120 series complies with UL/CUL/CE safety standards and also meets the EMC requirements of heavy industrial immunity level (EN61000-6-2).
Applications could include industrial control system, semi-conductor fabrication equipment, factory automation, electro-mechanical applications, and marine related installations.
