Rated at 12 volts DC and 20 amps total output, this unit delivers regulated power across 18 individual outputs, each protected by a resettable PTC (positive temperature coefficient) fuse. When a short circuit occurs on any output, the PTC fuse trips automatically. Once the fault is cleared, the fuse resets without manual replacement. A built-in on\/off power switch with LED indicator and a lockable metal enclosure round out the panel-level safety features. Security installers and low-voltage technicians are the primary end users.\u003c\/p\u003e\n\u003cp\u003eThis power supply panel is suited for residential and commercial CCTV deployments where multiple cameras must be powered from a single, centrally located distribution point. It is particularly well matched to night vision cameras equipped with IR LEDs and to standalone IR illuminators, both of which can draw higher inrush current that benefits from per-channel overcurrent protection. The 18-channel layout supports medium-to-large camera counts in a single enclosure, reducing homerun wiring and simplifying load management across a system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 individually PTC-fused output channels with automatic reset after fault is cleared\u003c\/li\u003e\n  \u003cli\u003ePer-channel short-circuit indicator light identifies the faulted camera output immediately\u003c\/li\u003e\n  \u003cli\u003eProtections include over-voltage, over-current, short-circuit, and surge\u003c\/li\u003e\n  \u003cli\u003eOn\/off safety power switch with LED status indicator\u003c\/li\u003e\n  \u003cli\u003eLockable beige metal enclosure for secured, tamper-resistant installation\u003c\/li\u003e\n  \u003cli\u003eRecommended for IR night vision cameras and IR illuminator loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style distributed power panel for 12 volt DC CCTV camera systems requiring multi-channel overcurrent protection at a central distribution point.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this panel should be performed by a licensed low-voltage or security systems technician in accordance with applicable local electrical codes and NEC Article 725 guidelines for Class 2 and Class 3 remote-control and signaling circuits. Power down the panel completely before making or changing any wiring connections on the output terminals. Do not exceed the 20-amp total system load across all 18 channels. Verify that each camera run is correctly terminated before restoring power, and use the per-channel indicator lights to confirm normal operation on initial startup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Voltage\u003c\/strong\u003e: 12 volts DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Output Current\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Output Channels\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: PTC resettable fuse per channel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProtections\u003c\/strong\u003e: Over-voltage, over-current, short-circuit, surge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Material\u003c\/strong\u003e: Metal (beige finish with lock)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndicator\u003c\/strong\u003e: LED power indicator, per-channel short-circuit indicator lights\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GENERIC \/ UNBRANDED\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: w12vdc18p\/20a\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Generic \/ Unbranded","offers":[{"title":"Default Title","offer_id":51524055433522,"sku":"W12VDC18P\/20A","price":142.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ce2f9ab06869750a88bb419431909e3.jpg?v=1785444879","url":"https:\/\/voomisupply.com\/products\/generic-w12vdc18p-20a-12vdc-20a-18-channel-ptc-power-supply","provider":"Voomi Supply","version":"1.0","type":"link"}
