Abstract
Provided is a power supply testing system which is used for conducting a burn-in test on a power supply device. The power supply testing system comprises a switch module, a temperature sensing unit, a control module and a heating refrigeration module. The switch module inputs a preset temperature value into the control module, and the temperature sensing unit senses a temperature signal at the position of the power supply device and sends the sensed temperature signal to the control module. When the temperature sensing unit senses that temperature is lower than preset temperature, the control module sends a first control signal to the heating refrigeration module, the heating refrigeration module reduces the temperature of the position of the power supply device till the temperature sensed by the temperature sensing unit equals the preset temperature.
