CCTV Power Supply 12V DC 10A 4/9/18CH Distribution Box U/L Security Camera PSU

Power your complete CCTV security camera system with this professional-grade UL Listed power distribution box. This versatile 12V DC power supply can power 4, 9, or 18 security cameras depending on your system configuration and camera power requirements. With individual channel protection, real-time LED status monitoring, and regulated filtered output, this is the reliable power solution for residential, commercial, and professional surveillance installations. MODEL: W-UL12VDC-9P/10A INPUT: 110-120V AC, 50/60Hz OUTPUT: 12V DC Regulated and Filtered TOTAL POWER: 10 Amps / 120 Watts CHANNELS: 9 Independent Fused Outputs CAMERA CAPACITY: 4, 9, or 18 Cameras (depending on camera power consumption) CONNECTION: Plug-in AC power cord, hardwired screw terminal outputs Perfect for powering analog CCTV cameras, HD-TVI cameras, HD-CVI cameras, AHD cameras, IP cameras requiring 12V DC, PTZ cameras, dome cameras, bullet cameras, IR illuminators, video baluns, DVR accessories, access control systems, and complete professional surveillance installations up to 18 cameras. ═══════════════════════════════════════════════════════════════════════════ FLEXIBLE CAMERA CAPACITY – POWER 4, 9, OR 18 CAMERAS This power supply provides 9 independent channels with 10 amps total capacity, allowing you to power anywhere from 4 cameras up to 18 cameras depending on each camera’s power consumption. POWER 4 HIGH-CONSUMPTION CAMERAS High-power PTZ cameras, cameras with heaters, or cameras with powerful IR illuminators that draw 2.0-2.5A each. Use 2-3 channels per high-power camera by paralleling outputs for higher current capacity. POWER UP TO 9 STANDARD CAMERAS Standard analog CCTV cameras, HD cameras, or IP cameras drawing 800mA to 1.6A each. Connect one camera per channel for maximum protection and monitoring capability. Ideal for typical 4-camera, 8-camera, or 9-camera residential and small business systems. POWER UP TO 18 LOW-POWER CAMERAS Low-power cameras or cameras without IR illuminators drawing 400-550mA each. Connect two cameras per channel by using terminal splitters or wire nuts. Perfect for large commercial installations with many cameras distributed across your property. TYPICAL CAMERA POWER CONSUMPTION EXAMPLES Low Power Cameras 300-500mA: Standard dome cameras without IR, basic bullet cameras in daylight areas, indoor cameras without night vision Medium Power Cameras 600-900mA: HD analog cameras with moderate IR, varifocal cameras, standard outdoor cameras with IR LEDs up to 100 feet High Power Cameras 1000-1600mA: Cameras with long-range IR illuminators 150+ feet, PTZ cameras, cameras with built-in heaters for cold climates, 4K resolution cameras CALCULATE YOUR SYSTEM CAPACITY Add up the amperage of all your cameras. Total must be 10A or less. Divide cameras across the 9 channels based on individual camera power needs. Each channel is individually protected with PTC auto-reset fuse, so you can mix different camera types safely. ═══════════════════════════════════════════════════════════════════════════ KEY FEATURES AND ADVANCED PROTECTION INDIVIDUAL PTC AUTO-RESET FUSE FOR EACH OUTPUT Each of the 9 channels features its own PTC (Positive Temperature Coefficient) auto-reset fuse that provides independent protection. If one camera shorts out, draws too much current, or malfunctions, only that channel trips – all other cameras continue operating normally. The PTC fuse automatically resets when you fix the problem. No manual reset required. No fuse replacement needed. This is professional-grade protection that prevents a single camera failure from taking down your entire security system. INDIVIDUAL LED STATUS INDICATOR Every channel has its own bright LED indicator light that shows power status at a glance. Instantly identify which cameras are powered and which channels may have issues. No more guessing with a multimeter or testing cables one by one. LED on means that channel is providing power. LED off means no load connected, camera disconnected, or PTC protection has tripped. Essential for quick troubleshooting and system monitoring. MAIN POWER SWITCH WITH SURGE PROTECTION Built-in master power switch with integrated surge protection safeguards your entire camera system against power spikes, voltage surges, and electrical transients. Protects against lightning strikes, utility power fluctuations, and equipment switching surges. The main switch makes it easy to power down the entire system for maintenance without unplugging cables. SWITCH MODE POWER TECHNOLOGY All DC models use advanced switch mode power supply (SMPS) technology for high efficiency, compact size, and superior performance. Operates at greater than 82% efficiency compared to 50-60% for old transformer-based designs. This means less wasted energy, lower electricity costs, reduced heat generation, and longer component life. Lightweight and compact design saves installation space. REGULATED AND FILTERED OUTPUT All DC models are regulated and filtered to provide clean, stable 12V DC power with minimal ripple and electrical noise. Regulated voltage means your cameras receive consistent 12V regardless of input voltage fluctuations, number of cameras connected, or power supply loading. Filtered output eliminates electrical interference that can cause video noise, poor image quality, or premature equipment failure. Professional power quality for professional results. UL LISTED SAFETY CERTIFICATION UL Listed certification means this power supply has passed rigorous independent testing for electrical safety, fire safety, and reliability. Required for commercial installations, insurance compliance, and building code requirements. Not a cheap import without proper certification – this is professionally certified equipment that meets North American safety standards.
