Power supply control system and power supply control method for server device

Abstract

This invention discloses a power supply control system and a power supply control method for a servo device. The power supply control system includes an electronic switching device and a control module. The electronic switching device includes a control element and a switching element, and the control module is connected to the control element. When the control element detects an abnormal condition, it controls the switching element to a first state to block the power supply from the power supply device to the load and outputs a first quasi-signal to the control module. The control module is configured to determine whether the number of times the control element outputs the first quasi-signal within a predetermined time has reached a critical number. When the number reaches the critical number, the control module sends the first quasi-signal to the control element. When the control element sequentially receives the first quasi-signal and the second quasi-signal from the control module, the control element initiates a reset mechanism.
