PSU1210C – Power supply 12VDC-20A, Adjustable Voltage 12V±10%



110V-240V AC to DC 12V 20A, Adjustable Voltage 12V±10% Regulated Switching Mode Power Supply, 240W Power Supply for CCTV Surveillance Cameras, etc
12VDC 20A SMPS (240W) DC Metal Power Supply
Switching power supply using pulse width modulation (PWM) switching technology designed to ensure power supply stability and high efficiency. Its anti-interference protection, ensures long-life of the CCTV cameras.

A regulated switched-mode power supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power) to DC loads, such as a personal computer, while converting voltage and current characteristics. Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation, full-on and full-off states, and spends very little time in the high dissipation transitions, which minimizes wasted energy.

The output voltage of the regulated switching mode power supply is adjustable via a turn button, its range is 10.8~13.2V. This voltage range helps this power supply to be used in a wide range of applications, e.g. long distance CCTV installations where there is voltage drop due to cable losses.
