Click on View [ Dimension & Mounting / wiring terminal/The type of gas ]
 
 ■ Characteristic:
Independent self-control integrated charge mode
Automatically switch the main power supply backup power
Perfect battery charging and maintenance functions, high efficiency, nice electrical and magnetic compatibility,
Discharge of a battery overload protection 100% full load burn-in test
high accuracy of regulation, long operation life
low operating temperature Output ripple small
 
 ■ Working theory:
 
  Switching power supply,used by fire control only, is mainly made of Input EMI filter, Rectifier filter circuit, Power conversion circuit, PWM controller circuit,Output rectifier filter circuit,backup battery charging circuit,Main and backup power automatic switching circuit,status signal output circuit and some protected units. If the switch power supply accesses battery, it will be composed of uninterrupted DC power supply system. With the high reliability, switching power supply is suitable for some strict requested trades, such as industry, fire control, and some places with a variety of special power supply requirements.
