Intermittent life test system

The invention relates to the technical field of product reliability tests, in particular to an intermittent life test system which comprises a plurality of single-path sub-control systems connected in parallel. The single-path sub-control system comprises a power supply module, a switch module and a control detection module, and the power supply module is connected with the switch module and used for supplying power to the test system; the switch module is connected with the control detection module and is used for controlling the on-off of one or more single-path sub-control systems, and the control detection module is used for controlling the on-off time of a power supply and detecting the magnitude of current. The plurality of single-path sub-control systems are connected in parallel, the switch module is connected with the control detection module and selectively controls the on-off of one or more single-path sub-control systems, and when the plurality of single-path sub-control systems are controlled, th
