WAGO 787-734 Switched Mode Power Supply

WAGO 787-734 Switched-mode Power Supply

Product Introduction

The WAGO 787-734 is a high-performance switched-mode power supply designed for industrial applications, offering a stable 24 VDC output at 20 A (480 W) with precise voltage regulation. Engineered for reliability in control cabinets, it features natural convection cooling for horizontal mounting, tool-free termination via lever-actuated PCB terminal blocks, and electrical isolation compliant with SELV (UL 60950-1) and PELV (EN 60204). The power supply supports a wide input range (85–264 VAC/130–373 VDC), ensures low ripple (<100 mV), and includes a DC OK contact for system monitoring.
