CH-3220-18CH 12VDC 20A 18-Channel Power Supply Box (Non-UL)

Product Overview

The CH-3220-18CH is a high-capacity centralized DC power distribution box engineered to deliver reliable 12 VDC power to up to 18 security cameras, access control devices, or surveillance accessories. Supplying a total output capacity of 20 Amps (240 Watts), this metal-enclosed power supply replaces individual AC wall adapters with a single, neatly organized power hub.

Housed in a heavy-duty, wall-mountable steel cabinet with a key lock, each of the 18 PTC fuse-protected channels prevents single-camera power faults or short circuits from taking down the rest of the security system. Individual LED status indicators for each output channel provide instant visual feedback for fast system troubleshooting during maintenance.
