Abstract: A power output control module for power distribution is installed inside a power distributor that is connected to an AC power source and multiple electronic devices to control the AC power outputted to the electronic devices. The power output control module continuously detects whether the AC power inputted is normal. When the AC power source is disconnected by accident, a latch relay is controlled to switch to be open, so that the AC power source and the electronic devices are disconnected. This prevents the instantaneous surge current from damaging the electronic devices when the AC power source resumes its normal output and also increases the safety and reliability of electronic devices.
