Switched-Mode Power Supplies (SMPS) are an essential component in modern CCTV surveillance systems, providing efficient and reliable power conversion. Unlike traditional linear power supplies, SMPS use high-frequency switching to regulate voltage and minimize energy loss, making them ideal for security camera setups that require stable and uninterrupted power.
In this guide, we will explore how SMPS works, its advantages, applications in CCTV surveillance, and a detailed look at some of the best power supply products available from Hi-focus.
How Does an SMPS Work?
An SMPS converts AC power into DC power through a series of steps:
AC to DC Conversion: The input AC voltage is first rectified and filtered to produce an unregulated DC voltage.
High-Frequency Switching: A high-speed transistor switches the DC voltage on and off rapidly to generate a high-frequency AC signal.
Voltage Regulation: The high-frequency AC is then rectified and filtered to produce a stable DC output.
Feedback Control: A feedback loop continuously monitors and adjusts the output voltage to maintain stability.
This efficient process ensures minimal energy loss, making SMPS a preferred choice for powering CCTV surveillance systems.
Advantages of SMPS for CCTV Surveillance Systems
High Efficiency: Due to minimal heat dissipation, SMPS can achieve efficiency levels above 80%.
Stable Power Delivery: Ensures uninterrupted operation of CCTV cameras, reducing the risk of power fluctuations.
Compact Size: The use of high-frequency switching reduces the size of transformers and components, making installation easier.
Wide Input Voltage Range: Can operate over a broad range of input voltages, making them suitable for different locations.
Better Heat Dissipation: Advanced designs include built-in EMI filters and metal enclosures to improve thermal management, essential for surveillance equipment longevity.
