Description
WDR-480 series is a 480W 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, width (85.5mm) in slim design, -40〜+85°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-480 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-480-24 is a key model in the WDR-480 series, offering a reliable 24V DC output with up to 20A current, delivering 480W of continuous power. This wdr-480-24 power supply features an adjustable voltage range from 24V to 28.8V, providing flexibility to meet various industrial needs. With high efficiency up to 91%, complete protections (short circuit, overload, over voltage, over temperature), and compliance with international safety standards, the Mean Well WDR 480 24 ensures stable performance in demanding environments. The WDR-480-24 is an ideal choice for industrial automation, control systems, and machinery applications.
The WDR-480-48 offers a 48V DC output with a current capacity of up to 10A, making it suitable for equipment requiring higher voltage levels or longer transmission distances. Like the 24V version, the WDR-480-48 power supply supports an adjustable output voltage from 48V to 55.2V, ensuring adaptability across a wide range of industrial scenarios. With its slim design, high reliability, and ability to operate in harsh environments, the WDR-480-48 is widely used in telecommunication systems, security equipment, and process automation where stable and efficient power delivery is essential.
In addition to the WDR-480 series, Mean Well offers a complete WDR family of DIN rail power supplies to meet a wide range of power demands:
The WDR-60 series (including models WDR-60-24 and WDR-60-48) provides 60W output with the same ultra-wide AC input range (180〜550Vac). Its compact size and reliability make it ideal for smaller industrial devices, control panels, and communication systems.
The WDR-120 series (such as WDR-120-24 and WDR-120-48) delivers 120W output, offering a balance of size and power for medium-scale automation and instrumentation.
The WDR-240 series (including WDR-240-24 and WDR-240-48) supplies 240W power, designed for higher power consumption equipment while maintaining a slim, space-saving design.
The WDR-480 series (with WDR-480-24 and WDR-480-48) is the highest capacity in the family, offering 480W output for heavy-duty industrial applications.
With wide input voltage tolerance, high efficiency, robust protection features, and reliable performance across all models, the Mean Well WDR series serves as a versatile and trusted power solution for industrial automation, telecommunications, surveillance systems, and more.
