Medium and High Voltage Wiring Harness Test System
The FPC/CCS Medium and High Voltage Wiring Harness Test System is capable of testing 16/48/96/192 points, and the system adopts the hybrid testing approach of internal 4-wire and external 4-wire. The equipment possesses the following test functionalities: rapid OS test, precise OS test, 2-wire resistance test, 4-wire DC on-resistance test, 4-wire LCR test, insulation resistance test, and AC/DC withstand voltage test.
Distributed Architecture (Distributed Version)
It is capable of forming a distributed system with a maximum of 192 points or more.
Modular Design
Each test instrument integrates 1 test card and 12 switching array cards, each featuring 16 test points, and supports 2-wire and 4-wire mixed testing.
Multi-Functional Testing
The test board integrates the OS test function, DC resistance test function, LCR test function, AC/DC insulation withstand voltage test function, and LCR test function. It also includes DC resistance, LCR, AC/DC withstand voltage, insulation resistance, and a programmable power supply.
Highly Accurate On-Resistance
The on-resistance test offers a maximum of 1A test current and a minimum resistance resolution of 10μΩ.
Self-Learning Function for Quick Detection of Unknown Harness Connections.
