High-Capacity Centralized Power for Large-Scale Surveillance
The 20A 18-Channel CCTV Power Supply Box is the professional choice for managing power in extensive security installations. Engineered to provide a stable 12V DC output across 18 individual channels, this 240W unit eliminates the need for bulky individual power adapters. It is specifically designed to support high-draw IR night-vision cameras, ensuring consistent performance across your entire premises, whether for a large residential estate or a commercial warehouse.
Advanced Fail-Safe Protection
System reliability is paramount in security. Each of the 18 channels is equipped with an independent PTC (Positive Temperature Coefficient) auto-reset fuse. In the event of a short circuit or overload on a single camera, the PTC fuse triggers to protect the rest of the system. Once the fault is cleared, the fuse automatically resets—minimizing downtime and reducing the need for manual maintenance or fuse replacements.
