Wago Switching Power Supply for Industrial Applications
The Wago 2587-2144 power supply is a reliable and robust device designed to provide a stable continuous voltage of 24 VDC with a nominal current of 5 A. It is ideal for electrical panels, industrial automation, control systems, PLCs, sensors, actuators, and all applications requiring a constant and secure power supply.
Thanks to high-efficiency switching technology, it ensures stable delivery even in the presence of electrical network variations, protecting sensitive loads and ensuring operational continuity.
Natural Convection Cooling and Silent Operation
The power supply is designed for horizontal mounting with natural convection cooling, eliminating the need for internal fans.
This ensures:
-
completely silent operation;
-
longer lifespan;
-
reduction of mechanical failures;
-
better reliability in harsh industrial environments.
Push-in Connection for Quick Installation
The push-in connection technology allows for quick and secure wiring of the power supply without tools, reducing installation time and ensuring a stable electrical contact.
The front DC-OK LED provides immediate visual feedback on the correct operation of the output, facilitating field diagnostics.
Advanced Electrical Performance
The power supply supports a wide input range (from 90 to 264 VAC) and is equipped with integrated protections and reliable control logic. The 50 ms network drop compensation function ensures stability even in the presence of micro interruptions.
The adjustable output voltage (23.5-28 VDC) allows adaptation to different devices and variable cable lengths, while the residual ripple of 100 mV ensures a clean power supply, essential for sensitive electronic equipment.
In case of overload or short circuit, the power supply intervenes with automatic shutdown and restart, protecting both the device and the connected load.
Parallel or Series Operation
The Wago 2587-2144 model can be used:
-
in parallel to increase the available current;
-
in series to increase the total voltage.
This flexibility makes it particularly suitable for modular applications and complex systems requiring redundant power supplies or customized voltages.
