Description

WDR-120 series is a 120W DIN rail power supply with ultra-wide AC input range. It is suitable to be mounted on TS-35/7.5 or TS-35/15 rails. Main features are as following: it can accept 180〜550Vac ultra-wide input voltage range for single phase or 2-phase system, easy to install DIN rail type, narrow width (40mm) in slim design, -25〜+70°C wide range operating temp, 4.7KVAC high isolation voltage, operation at 2000m altitude, adjustable output voltage (+20% max.), high efficiency, low ripple & noise, complete protections and so on. WDR-120 is compliant with BS EN/EN-61000-6-2 standard regarding immunity for industrial environments. It suitable for industrial automation, surveillance, telecommunication and more applications.

The WDR-120-12 model offers a 12V output, making it ideal for low-voltage systems and devices that require stable, reliable power. Its slim design and wide input range make it a versatile solution for various industrial applications.

The WDR-120-24 model provides a 24V output, suitable for powering standard industrial systems and equipment that demand moderate voltage levels. With high efficiency and a robust design, this model ensures long-term, reliable operation even in challenging environments.

The WDR-120-48 model delivers a 48V output, ideal for high-power industrial applications, telecommunication systems, and other demanding operations that require a stable and efficient power supply. Its high isolation voltage and wide operating temperature range make it perfect for industrial automation and more.

In addition to the WDR-120, the Mean Well WDR series offers a variety of models to meet diverse power requirements. The WDR-60 series provides up to 60W of output power, designed for low-power industrial applications that require compact and efficient power supplies. This model retains all the key features of the WDR series but in a more compact size, making it ideal for space-constrained environments without compromising on performance.

The WDR-240 series provides up to 240W of output power, ideal for higher power applications in industrial environments. It shares similar features with the WDR-120 but with increased power capacity and broader voltage output options, making it perfect for systems that demand more power while maintaining compact design and high reliability.

The WDR-480 series extends this further to 480W, suitable for more robust and energy-demanding industrial applications. It is designed with high efficiency and multiple output options, providing versatility for a wide range of systems, including automation and telecom solutions that require high-output power.

All models within the WDR series maintain Mean Well’s commitment to delivering high-quality, efficient, and reliable power solutions for industrial, telecommunications, and automation systems.
