W-12VDC-18P20A UL 12V DC 20Amps 18-Channel UL-Listed Power Supply

Product Overview

The W-12VDC-18P20A UL is a high-performance 18-channel 12V DC power supply engineered for professional surveillance and network applications. Each channel delivers 1.11A with precise voltage regulation of ±5% even under full load, supporting reliable operation of multiple devices simultaneously. Equipped with short-circuit, overload, and surge protection, the unit automatically shuts down and restarts faulty channels without affecting the others. Operating efficiently at over 80% efficiency, it accepts 110–120VAC input and works across a temperature range of 0°C to 40°C with up to 95% relative humidity. UL certification ensures compliance with safety standards, while compact dimensions make it suitable for rack-mounted or centralized installations. This combination of high efficiency, multi-channel management, and protective features makes it ideal for demanding CCTV or network deployments.
