WAGO 2587-2147 Switched-Mode Power Supply 1-Phase 24 VDC 20 A 480 W

The WAGO 2587-2147 is a 1-phase switched-mode power supply delivering a 24 VDC SELV output at 20 A (480 W). It accepts a wide-range 100–240 VAC input with active power factor correction, provides a DC-OK LED for visual status monitoring, and uses Push-in CAGE CLAMP technology for tool-free wiring. The unit mounts on a DIN-35 rail and supports parallel and series operation with a second identical device via natural-convection cooling in the horizontal mounting position.
