A 4-channel SMPS (Switched Mode Power Supply) is a type of power supply designed to provide power to multiple devices, typically CCTV cameras, from a single input. It features four separate channels, each capable of supplying power independently to one camera or device. SMPS technology is known for its efficiency and reliability, converting AC input to DC output using high-frequency switching circuits.Â
Here’s a more detailed look:
Channels:
A 4-channel SMPS has four individual output ports (or channels).Â
Voltage Output:
Most 4-channel SMPS units provide a standard 12V DC output, which is the common requirement for CCTV cameras.Â
Switched Mode Power Supply:
The SMPS converts the AC input (from the mains) into the DC output required by the cameras using a switching regulator,
Safety Features:
Many 4-channel SMPS units include safety features like over-voltage protection, over-current protection, and short-circuit protection to safeguard both the power supply and the connected devices.Â
Low Ripple Voltage:
Some SMPS units are designed with low ripple voltage, which helps reduce noise and interference.Â
Efficiency:
SMPS technology offers high efficiency, minimizing energy loss and heat generation.Â
Applications:
4-channel SMPS units are commonly used in CCTV systems, providing power for up to four cameras simultaneously.Â
Indicator LEDs:
Some 4-channel SMPS have power LED indicators for each channel, showing the power status for each individual camera.Â
