SC6540 multiplexer


The SC6540 multiplexer provides a sophisticated solution for multi-point electrical safety testing, allowing users to switch between Hipot, ground bond, and insulation resistance tests automatically. By integrating with high-performance testers, it streamlines the evaluation of complex products without the need for manual intervention. This versatility ensures that production lines can maintain high speed while ensuring comprehensive safety compliance across all test points.

Built for demanding production environments, the SC6540 features a modular design that can be configured with high-voltage or high-current channels. The system supports up to 40 A for ground bond tests and up to 6 kV DC for insulation resistance and dielectric withstand tests. Its robust switching technology reduces setup costs and minimizes the risk of human error by automating the connection process during the testing cycle.

As a modular scanning matrix, the SC6540 can be expanded to meet the needs of large-scale operations by linking a master unit to four secondary units. It offers seamless integration with industry-leading testers like the OMNIA II, HypotULTRA, and LINECHEK II via USB, RS-232, or Ethernet. This flexibility allows for highly customized test sequences that can be fully managed through automated PC-driven software for maximum efficiency.
