Distribution Box CCTV Power Supply
12 productsElectrical Distribution Box CCTV Power Supply is a specialized power supply device that is primarily used to power closed circuit television (CCTV) surveillance systems. This device is designed as a box-like structure containing multiple power output channels, which can supply power to multiple surveillance cameras or other CCTV devices. 12V and 24V outputs and 4CH/9CH/18CH are provided.
A distribution box power supply takes a single high-voltage AC input and converts it into multiple, individually protected low-voltage DC outputs. This setup is perfect for powering several devices like security cameras or separate runs of LED strip lights from one central unit, cleaning up the wiring significantly. Instead of juggling a mess of individual plug-in adapters, you get a single, organized metal enclosure. SuperLightingLED's range of distribution power supplies provides stable 12V and 24V DC power, with models offering 4, 9, or 18 separate output channels to match the scale of your project.
These units are built for reliability and safety. The all-metal chassis protects the internal components, and every channel has its own fuse. This means if one connected device has a short circuit, it won't take down the entire system — only its own channel is affected. This is critical in both security and lighting applications where you can't afford a total failure. Our models cover a power spectrum from 60W for smaller jobs up to a hefty 480W for large-scale installations.

What's inside an LED power supply box?
An LED power supply box, often called a distribution box, combines a main AC-to-DC switching power supply with a fused terminal block inside a single metal case. This integrated design simplifies installations by providing a central point for all your low-voltage wiring. Our units accept a universal AC input (100-260V) and provide multiple screw-down terminals for your 12V or 24V devices. Each output is individually protected, and many models feature LED indicators to show the status of each channel at a glance.
Distribution Box Power Supply: Features and Protections
When you're running multiple cameras or long, separate runs of LED strip lights, managing power is key. Our distribution box power supplies are designed to make that job easier and safer. The standout feature is the per-channel protection. Most of our models use Auto-Reset PTC fuses. Unlike traditional glass fuses that blow and need to be replaced, a PTC fuse will automatically reset itself once the fault (like a short circuit) is cleared. This saves enormous time and hassle, especially if the power supply box is installed in a hard-to-reach location.
Beyond the fuses, these units have a full suite of built-in electrical protections:
- Overload Protection: Automatically cuts power if the connected devices draw too much current.
- Over-Voltage Protection: Safeguards your equipment from damaging voltage spikes.
- Short Circuit Protection: Prevents damage to the power supply and connected devices in case of a wiring short.
- Thermal Cut-off: Shuts the unit down if it overheats, protecting internal components.
The heavy-duty metal housing on most models isn't just for show; it provides impact resistance and helps dissipate heat. The inclusion of a lock and keys on the 9- and 18-channel units prevents unauthorized access or tampering with the wiring, a crucial feature for commercial or public installations.
Frequently Asked Questions About Distribution Box CCTV Power Supplies
Got questions about powering your camera or LED setup? I've answered thousands of them over the years. Here are the most common ones I get for these distribution boxes.
The main purpose of a Distribution Box CCTV Power Supply is to replace a messy pile of individual power adapters. It takes one AC mains input and gives you multiple, individually fused DC outputs—typically 4, 9, or 18—all in a single, organized metal case. It's a cleaner and more reliable way to power multiple cameras, LED light runs, or other low-voltage devices from one central spot.
It's simple math. Add up the power draw (in amps or watts) of every camera or LED strip you plan to connect. Then, add a 20% safety margin to that total. Don't run the power supply at 100% of its rated load; it'll run hot and its lifespan will drop. So if your total load is 80W, you need a power supply of at least 100W. Our guide to power calculations walks through it step-by-step.
No, and this is a common point of confusion. These distribution boxes are not waterproof and are designed for indoor or protected environments, like an attic, equipment closet, or garage. If you need to power something outdoors, you'll need one of our IP67 waterproof power supplies designed to handle direct rain and weather.
Individual fuses are a critical safety feature. If one of your connected devices—say, a camera—has a short circuit, it will only blow its own dedicated fuse. The other 17 channels will keep running without interruption. Without this, a single faulty camera could bring down your entire system. It makes troubleshooting a lot easier, too.
Absolutely. While they're designed for security systems, they work perfectly for LED lighting installations that have many separate, shorter runs. Think retail shelf lighting, under-cabinet lights, or display cases. Instead of a dozen small drivers, you get one clean, central power source. Just match the box's voltage (12V or 24V) to your LED strips.
Reliability and organization. A wall full of individual adapters creates a wiring mess and multiple points of failure. If one adapter fails, you have to figure out which one it is. With a distribution box, you have one high-quality power source, cleaner wiring, and individual protection that makes it easy to find a problem. It's the professional way to do it.
Security. These boxes are often installed in locations where you don't want unauthorized people messing with the power to your security system. The lock prevents tampering, whether it's accidental or intentional. It ensures that your camera feeds or access control systems stay powered on and secure.
Both. The whole box has a total maximum amperage—for example, the 240W 20A 18CH DC12V model can deliver 20 amps total. But each individual channel is also limited by its fuse, which is typically around 1 to 2 amps. You can't draw 10 amps from a single channel, even if the total supply has the capacity. This protects the wiring to each individual device.
