Cctv Power Supply For Video Camera Security System, Ac To Dc Power Adapter With Input Output Socket Plug

CCTV POWER SUPPLY

Specification

Installation

Output socket 5.5*2.1mm, DC power cord 1500mm, input ac plug CN/US/EU type optional

Features
PULSE WIDTH MODULATION SWITCHING CIRCUIT SCHEME:Adopt PWM scheme advanced control chip which is mature and reliable for many years. low loss, high efficiency,low temperature rising. Provide a stable and reliable power solution for CCTV.
MANUFACTURING PROCESS: By applying smd chip technology and smd components,significantly improve product stability, reduce the power

supply's weight.
TRANSFORMER: pure copper winding, secondary winding specially added copper slice as a heat conduction material, effectively control temperature rising
OUTPUT INDUCTOR:More coil turns and higher permeability leads to high inductance.Output inductor using sendust as core material. With high inductance,power supply's size is smaller and weight is lighter.
EMI CIRCUIT:Adopt perfect anti-electromagnetic interference circuit design to meet EMI control requirements and design standard, effectively avoid enviormental electromagnetic interference.
PROTECTION CIRCUIT: With built-in separate overload, short circuit protection circuit to ensure that in case user's system is abnormal, no safety problems occurs, neither damage occurs to the system. Provide stable, reliable and safe power supply to customers.
