Output Enable/Disable Button: In the process of using the bench power supply, Output button can prevent us from forgetting to turn off the output and causing damage to the load. Just press this button to turn on or turn off the output of the power supply. This makes it more convenient for you to use the variable power supply.
Overcurrent Protection: When the OCP function is turned on, if the load equipment is short-circuited during operation, the adjustable power supply will automatically stop output and send a buzzer to alert the user. Protect the adjustable power supply and load from damage.
