WDR-120 Series 120W Slim Dim Rail Type with Wide Range Single Phase Input

In response to the rapid growing applications as well as the narrower width request of DIN rail power supplies, MEAN WELL introduced a new DIN rail family features with single phase wide input range ~ WDR family. WDR-120 series, 120W AC/DC slim DIN rail power supplies with extreme high efficiency, are firstly launched to the market now. This new series equip with 180 to 550Vac single phase wide input range. They can be used in general power system with single phase 230Vac input or can capture one phase from the 330~550Vac three-phase power system, which can greatly increase the flexibility of system deployment.



With up-to-date circuit design, WDR-120 series possess up to 92% of extreme high efficiency and can provide 120W continuously up to 60℃ by only free air convection, or operate under 70℃ ambient temperature by suitable power derating. The slim design of 40mm in width helps save the precious space on the rail and also makes it 30.58% smaller in size compare to its predecessor model DRH-120 (120W, 340~550Vac/ single phase). Meanwhile, with wider input range, WDR-120 also has 6% higher efficiency than corresponding models, which response to the trend of green power with energy saving concept. 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. WDR-120 series comply with UL/CUL/CE safety standards and also meet the EMC requirements of heavy industrial immunity level (EN61000-6-2). Suitable applications include industrial control system, semi-conductor fabrication equipment, factory automation, electro-mechanical applications, and marine related installation…etc.
