CCTV Power Supply (Closed)12V 30A

KSH 4800 EXCL OF VAT

FEATURES

FEATURES:

1. Enclosed Design:
   • The most notable feature of a closed power supply is its enclosed housing, which provides protection against dust, moisture, physical damage, and other environmental elements that could potentially affect the performance or longevity of the unit.
   • The enclosure typically includes ventilation slots or fans to help dissipate heat and maintain optimal operating temperature.
2. Multi-Channel Outputs:
   • Similar to open power supplies, a closed CCTV power supply provides multiple DC outputs that allow you to power several CCTV cameras or devices simultaneously. Depending on the model, it may have 4, 8, 16, or more channels.
   • The output voltage is generally 12V DC, which is the standard for most CCTV cameras. Some systems may support 24V DC for high-power cameras or specific applications.
3. Overload and Short Circuit Protection:
   • Closed CCTV power supplies typically feature built-in protection mechanisms such as overload protection, short-circuit protection, and over-voltage protection to safeguard both the power supply and connected devices.
   • These protections help prevent electrical faults from damaging the cameras or equipment.
4. Fused Outputs:
   • To ensure additional protection, each output channel in a closed power supply is often fused individually. This means that if there is a fault in one of the connected devices, it will not affect the others, and the fuse can be easily replaced without requiring the entire power supply to be replaced.
5. Heat Dissipation:
   • While the closed design provides protection, it also comes with mechanisms for heat dissipation, such as fans, ventilation holes, or heat sinks to prevent overheating, especially when powering a large number of cameras.
   • Some models may have a fan for cooling, while others may rely on natural convection through vents to allow heat to escape.
6. Compact and Organized Setup:
   • A closed power supply is often more compact and organized than an open design, with all wires and connections housed within the enclosure. This makes the setup neater, more secure, and easier to maintain.
   • The enclosure also helps minimize clutter and provides a professional look, particularly for installations in commercial or enterprise environments.
7. Power Rating:
   • Closed CCTV power supplies are available in different power ratings, typically ranging from 2A to 30A or higher, depending on how many cameras and devices need to be powered.
   • The total output power is important to ensure that the supply can handle the combined load of all connected devices.
8. Durability and Reliability:
   • The closed design ensures that the power supply can withstand the wear and tear of daily operation in a range of environments, providing a more durable and reliable solution for long-term surveillance setups.

CCTV Power Supply (Open)12v 5A

KSH 1000 EXCL OF VAT

Features: 

1. Multi-Channel Output:
   • These power supplies usually feature multiple DC outputs, which can power several cameras or devices simultaneously. The number of channels may vary, with typical options providing power for 4, 8, 16, or more cameras.
2. Voltage and Current Rating:
   • Most CCTV power supplies provide a 12V DC output, which is the standard for most surveillance cameras. However, some may offer 24V DC for high-power cameras or equipment.
   • The current rating will vary depending on the total power required by all the cameras connected to the power supply.
3. Open Frame Design:
   • The term “open” refers to the power supply’s un-enclosed nature, meaning it doesn’t come with a protective casing. The open design is typically used when the power supply is intended to be integrated into a larger system or custom enclosures, providing flexibility in the installation process.
   • This design also allows for easier access to connections and may allow for better heat dissipation due to the absence of a sealed casing.
4. Overload and Short Circuit Protection:
   • Quality CCTV power supplies typically feature overload protection, short-circuit protection, and over-voltage protection to prevent damage to the cameras and other equipment in case of electrical faults.
   • This ensures safety for both the devices and the power supply itself.
5. Efficient Power Distribution:
   • Power distribution boards with fused outputs are often used to prevent excessive current from damaging the system. Each camera or device is typically connected to a separate fused output for added protection.
6. Cooling Mechanism:
   • Some open CCTV power supplies may include fans or heat sinks to prevent overheating during operation, especially when powering multiple cameras or equipment that draw a substantial amount of power.
7. Durable and Reliable:
   • Despite the open design, the internal components of CCTV power supplies are typically built to last and designed for continuous operation, ensuring long-term reliability in surveillance systems.
