8250

High Voltage Cable Tester

The 8250 delivers advanced high voltage testing for demanding applications. With modular architecture, support for active components, and integration with external instruments, this system adapts to complex assemblies and scales for production environments of any size.

The 8250 now succeeds the CH2 model.

8250 High Voltage Tester

Experience unmatched flexibility with the 8250, our most powerful system for high voltage cable testing. Designed for complex assemblies such as harnesses and backplanes, the 8250 combines modular scalability with advanced capabilities to meet the demands of modern production environments.

Programming is fast and intuitive with options to auto-learn samples, create programs through the user interface, or import existing test files. The 8250 supports active component testing and integrates seamlessly with external instruments, including high-capacity power supplies and meters, for complete test coverage.

Modular base units and expansions allow you to distribute test points, minimize adapter cable lengths, and reduce costs. Multiple units can be combined for large assemblies or reconfigured for smaller setups without additional hardware, delivering maximum agility and efficiency.

Enhance your testing with advanced features such as high-speed test points for detecting intermittent connections, flexible modules for energizing relays and active components, and optional digital I/O for external device control. Built-in temperature and humidity monitoring ensures consistent performance in any environment.

Transitioning from the CH2 Platform

The 8250 is a direct replacement for the CH2 and is fully compatible with your existing cabling, adapters, and test programs.
