Medium and High Voltage Wiring Harness Comprehensive Test System
Medium and High Voltage Wiring Harness Comprehensive Test System can test 16/48/96/192 points, and the system adopts the hybrid test method of internal 4-wire + external 4-wire. The equipment has the following test functions: fast OS test, accurate OS test, 2-wire resistance test, 4-wire DC on-resistance test, 4-wire LCR test, insulation resistance test, AC/DC withstand voltage test.
Distributed architecture (distributed version)
Can form a distributed system with a maximum of 1920 points or more.
Modular design
Each test instrument integrates 1 test card and 12 switching array cards, each with 16 test points, and supports 2-wire and 4-wire mixed testing.
Multi-functional testing
The test board integrates OS test function, DC resistance test function, LCR test function, AC/DC insulation withstand voltage test function, AC/DC insulation withstand voltage test function, and LCR test function.
DC resistance, LCR, AC/DC withstand voltage, insulation resistance, and programmable power supply.
Highly accurate on-resistance
The on-resistance test provides a maximum of 1A test current and a minimum resistance resolution of 10μΩ.
Self-learning function for quick detection of unknown harness connections.
