The WAGO 2787-2144 is a next-generation, single-phase switched-mode power supply from the advanced Pro 2 series. Engineered for high-performance industrial applications, this 120W unit delivers a reliable 24V DC output with exceptional overload capabilities and integrated digital communication for smart power management .

Key Features and Product Highlights

• Pro 2 Series Advanced Technology: Part of WAGO's premier power supply family, offering enhanced efficiency, configurability, and diagnostic capabilities for demanding automation environments .

• Exceptional Overload Handling with TopBoost & PowerBoost: Features dual overload technologies: TopBoost delivers up to 600% of nominal current for short durations to trip circuit breakers, while PowerBoost provides 7.5A for 5 seconds to handle high inrush loads .

• Integrated Communication Capability: Equipped with a communication interface supporting IO-Link, Modbus RTU, and Modbus TCP via optional modules (2789-9080, 2789-9015, 2789-9052). Enables remote monitoring, configuration, and diagnostics .

• High Efficiency & Energy Savings: Delivers up to 93.8% efficiency, reducing energy costs and heat dissipation within the control cabinet .

• Configurable Overload Behavior: Overload response can be set to one of four modes: TopBoost, PowerBoost, constant current, or time-limited constant current, matching the protection strategy to the application .

• Comprehensive Signaling & Diagnostics: Features optical status indication (DC OK, load, warning/error states) plus a digital signal input and output (DI/DO) for external monitoring and control .

• CAGE CLAMP® Connection Technology: Tool-free spring pressure connections for fast, secure, and vibration-resistant wiring of input, output, and signaling terminals .

• Wide Input Range & Global Use: Accepts 90–264V AC and 130–240V DC input, suitable for worldwide single-phase AC or DC power networks .
