Our product emergency power off switch is mainly used for emergency power outages of DC power supply systems such as battery vehicles, electric forklifts, electric vehicles, and ordering instructions.
The role of the switch
1. The AC power input is rectified and filtered into DC;
2. Control the switching tube through the high frequency PWM (pulse width modulation) signal, and add that DC to the primary of the switching transformer;
3. High-frequency voltage is induced in the secondary of the switching transformer and supplied to the load through rectification and filtering;
4. The output part is fed back to the control circuit through a certain circuit to control the pwm duty cycle to achieve the purpose of stable output.
