Current Status of Electrical Performance Testing Technology for Contactors
the contact pressure drop, disconnect the contact between the voltage, the main circuit current and other electrical parameters of the sample sampling. The control part uses a digital I / O board to drive the contactor or relay on and off by controlling the solid state relay
A self-developed A / D sampling board or DSP as the core of the high-speed data acquisition card, the contact pressure drop, disconnect the contact between the voltage
The self-developed relay electrical life computer detection and control device in the relay electrical life test start, middle, the end of three different periods of time to capture the over-voltage signal.
The computer as a host computer, A / D sampling board or DSP as the next machine contact parameter automatic detection system
