The disable output function of APM AC/DC Power Supply:connect the corresponding terminal with the test product and set relevant settings in the menu. Once the tested product fails, change the level signal on the terminal to turn off the power output in time to reduce the loss. This function has been applied in some products test.

The following describes one application of this function.

The connection method of the terminal is shown as below figure. The Power Supply can output normally only when the switch is closed. If the tested product fails, the switch is off and the power supply output is also disconnected at the same time.

The connection method of the terminal is shown as below figure; the triggering process is the same as that of the SP-1U2U series DC power supply.

The external level signal triggers the power supply to turn off the output, and then the power supply is locked in the OFF state; when the lock state is released, the power supply will maintain the parameter settings before the output is locked and automatically turn on the output.
