WAGO Power Supply Base 3-Phase Output Current 40A DC-OK Contact

The WAGO Power Supply Base 3-Phase is a high-performance industrial power supply unit designed for demanding applications. With a 3-phase input and a robust 40A output current, it delivers reliable 24V DC power with an adjustable range of 22.5 to 28V. The integrated DC-OK signal provides a potential-free relay contact for monitoring and control. Ideal for automation systems, this DIN-rail mountable unit offers high efficiency up to 96% and features Push-in CAGE CLAMP® connection technology for fast and secure wiring.

Advantages

High efficiency up to 96% reduces energy costs and heat generation. The DC-OK relay contact enables easy integration into control systems for status monitoring. With 150% power boost for 5 seconds, it handles inrush currents reliably. Parallel operation of up to 5 units allows for increased power or redundancy. The wide input voltage range and robust design ensure stable operation in industrial environments.
