MEAN WELL introduce A new 240W AC/DC slim DIN rail power supply, with wide input range for both single and two phase power systems, to their din rail power supply range. DIN rail type power supplies are now widely used in industrial related applications because of their fanless and high reliability design; our new WDR-240 series completes the WDR product line.

Equipped with 180 to 550Vac wide input range, WDR-240 can be used in general power systems with single phase 230Vac input or can capture any two phases from 330~550Vac three-phase power systems, which can greatly increase the flexibility of system deployment.

With high efficiency circuit design that responds to green power requirements with energy saving concept, WDR-240 series possesses up to 91% high efficiency and can provide 240W continuously up to 50C using only free air convection, or operate under 70C ambient temperature, with suitable power derating. The slim width design of 63mm helps save precious space on the rail and also makes it 43.2% smaller in size compared to similar spec’d models on the market.

In order to enable these din rail power supplies to operate normally in areas susceptible to frozen temperatures, WDR-240 are equipped with low temperature power-on ability at -30C; other standard functions include DC OK relay contact alarm signal output, front panel LED indicator, front panel DC voltage adjustment, as well as protections for short-circuit, over load, over voltage, and over temperature.

WDR-240 series comply with UL/CB/CE certificates and also meet the EMC requirements of heavy industry immunity level (EN61000-6-2). Suitable applications include industrial control systems, semi-conductor fabrication equipment, factory automation, electro-mechanical applications, and marine related installations.
