Fonte de alimentação monofásica Woehrle EPNSV1202 comutada de formato estreito

Industrial control systems often struggle with unstable power delivery, especially in compact enclosures where space is at a premium. The Woehrle EPNSV1202 single-phase power supply solves this by delivering a reliable 24V DC output with 120W of power in a narrow, DIN-rail-mountable form factor. Its primary-switched design ensures high efficiency and stable performance, making it ideal for demanding automation environments.

Who is it for

This power supply is built for system integrators, panel builders, and maintenance engineers who need a compact, reliable power source for industrial control panels, PLC systems, sensors, and actuators. It is particularly suited for applications where DIN rail space is limited but performance cannot be compromised.

Tips

When installing the EPNSV1202, ensure adequate ventilation around the unit to maintain optimal cooling. For applications with high ambient temperatures above 55°C, derate the output power accordingly. Use appropriate wire sizes for the screw terminals to ensure secure and reliable connections. The adjustable output voltage feature allows fine-tuning for specific load requirements, but always verify the connected devices' voltage tolerance before adjustment.
