cctv power supply unit 12v 30a

Product Description

A 12V 30A CCTV Power Supply Unit (PSU) is a high-capacity regulated power supply designed to provide 12V DC power to multiple CCTV cameras and other compatible security equipment. With a maximum output of 30 amps, it is suitable for large CCTV installations where many cameras need to be powered from a centralized location.

Key features

• ⚡ 12V DC regulated output — provides stable power to compatible CCTV equipment.
• 🔌 30A maximum output — provides substantially more capacity than 10A or 15A CCTV power supplies.
• 📹 Multiple-camera support — can power a large number of 12V cameras, depending on their individual current consumption.
• 🛡️ Protection functions — commonly includes short-circuit, overload and over-voltage protection.
• 🔋 Centralized power distribution — allows multiple cameras to receive power from one location.
• 💡 Power indicator — shows when the PSU is operating.
• 🧰 Protective metal enclosure — commonly used to protect the power supply and its connections.
• 🌡️ Cooling/thermal protection — some models include ventilation or temperature protection to prevent overheating.
• 🔧 Easy maintenance — centralized connections make it easier to troubleshoot and maintain camera power.

Typical specifications

How it works

The PSU converts AC mains electricity into regulated 12V DC power. The 12V output is distributed to the connected CCTV cameras through individual power cables or distribution terminals.

For example, if each camera requires approximately 0.5A:

30A ÷ 0.5A = 60 cameras

This is a theoretical maximum based only on current capacity. In an actual installation, it is better to maintain a safety margin and account for IR night-vision LEDs, camera heaters, voltage drop and startup current.

Typical applications

• 📹 Large CCTV camera installations
• 🏢 Commercial buildings
• 🏭 Industrial facilities
• 🏫 Schools and institutions
• 🏨 Hotels and apartment complexes
• 🛍️ Shopping centres
• 🏘️ Residential estates
• 🚧 Large security compounds
