UL 2251 IEC 62196 Charging Gun Endurance Tester

Samples and

restrictions

Electric vehicle charging interfaces, industrial plugs, sockets and couplers

Test use

It is used to test whether electrical accessories such as electric vehicle charging interfaces, industrial plugs and sockets, and couplers can withstand the mechanical stress, electrical stress and thermal stress that occur during normal use without excessive wear or other harmful effects, with the purpose of verifying their reliability.

Test principle

The servo motor drive mechanism is used to perform linear plug-and-pull repetitive actions on the sample, and an external load can be connected for on-off testing. Power on and off time, test speed, stroke, and angle can all be preset through the touch screen.

Structure and features

It adopts an integrated frame, driven by a servo motor, precision ball screw and synchronous belt transmission, color touch screen operation and powerful digital display function, PLC intelligent control system; it also uses a three-axis adjustable clamp, suitable for charging gun interface life span test.
