Overview
The Woonyoung WYSP-75S24D is a premium, industrial-grade single-channel Switching Mode Power Supply (SMPS) engineered for high-density, reliable DIN rail mounting. Manufactured by Woonyoung (WoonyoungMicro) in South Korea, this highly stable module delivers a precise 24VDC output at 4.1A (75W). It is an exceptional choice for engineering labs, industrial automation panels, and rugged projects requiring clean, ripple-free power for PLCs, HMI display systems, and sensitive field sensors.
Key Features
Dual-LED Diagnostics: Features a green ON LED to confirm active power delivery and a dedicated red OC (Over-Current) LED for instant visual troubleshooting if the load drops or spikes dangerously.
Precise Voltage Tuning (V-ADJ): Includes an accessible front potentiometer allowing you to fine-tune the 24V output to compensate for natural line voltage drops over long cable runs.
Compact, Space-Saving Footprint: The slim, vertical chassis profile is designed to maximize rail density, letting you pack more hardware into crowded electrical enclosures.
Robust Safety Layer: Built-in hardware isolation shields your system from short circuits, over-temperatures, and severe power spikes via an integrated inrush current limiter.
