High-performance Wago switching power supply
The Wago 2587-2146 is a professional switching power supply designed to provide a stable continuous voltage of 24 VDC, with a nominal current of 10 A and a total power of 240 W. It is an essential component for electrical panels, industrial machines, automation systems, PLCs, I/O modules, and any equipment requiring reliable and safe power supply.
The compact design, quick wiring, and superior performance make it an ideal choice for installers and system integrators.
Guaranteed reliability with active PFC
Unlike simpler models, this power supply integrates an active power factor corrector (PFC), which optimizes current absorption from the network by reducing disturbances, losses, and non-linear loads.
The advantages of active PFC include:
-
better energy efficiency,
-
less interference on the network,
-
greater power stability,
-
compliance with international standards
Quiet operation with natural cooling
The power supply does not use fans: cooling occurs entirely through natural convection, ensuring:
-
absence of noise,
-
reduced maintenance,
-
longer component lifespan,
-
reliable operation even in industrial environments.
Horizontal mounting maximizes cooling efficiency and ensures consistent performance over time.
Push-in connection and immediate status indication
The push-in connection technology allows for quick and secure wiring without tools, reducing installation time and costs.
The front DC-OK LED provides immediate indication of the output voltage status, simplifying diagnostics and maintenance.
Precise and stable electrical performance
The adjustable output voltage from 23.5 to 28 VDC allows for compensation of cable drops or adjustment of power supply to specific devices. The 100 mV ripple ensures a clean power supply, essential for sensitive electronic equipment.
The protection logic with automatic shutdown and restart intervenes in case of short circuit or overload, preserving both the power supply and the load. This function is useful in industrial plants where operational continuity is essential.
Series and parallel operation
The Wago 2587-2146 is designed to work:
-
in parallel, increasing the available current;
-
in series, doubling the output voltage when necessary.
This flexibility is perfect for modular installations and complex systems
