WDR-120W DIN Rail Mounted Switch Power Supply

The WDR-120W DIN Rail Mounted Switch Power Supply is a dedicated three-phase input power unit engineered for industrial environments powered by three-phase electricity. Rated at 120W, it supports a wide three-phase AC input range of 200~480V, capable of directly converting standard industrial 380V three-phase mains power into smooth, stable DC voltage. Designed with robust industrial circuitry and a fully enclosed all-metal casing, this power supply boasts high energy conversion efficiency, an integrated 3-phase active PFC module, full-spectrum circuit safeguards, and reliable performance across a broad temperature span. Designed for quick snap-on installation on standard 35mm DIN rails, it effectively conserves cabinet internal space. It is extensively utilized globally in CNC machine tools, lifting machinery, large electrical control cabinets, and heavy-duty automated production lines.
