The SW2001 High Voltage Multiplexer is designed to connect multiple testers for six different tests, allowing safe and seamless switching between high-voltage and 4-terminal low-voltage testing. (It is designed to connect testers for the winding resistance test, inductance test, insulation resistance test, hipot test, surge test, and partial discharge test [ACPD and Surge PD].)
The multiplexer minimizes risk of damage to low-voltage test equipment by effectively mitigating the impact of stored energy in windings during high voltage testing such as hipot tests and insulation resistance tests. The robust multiplexing design ensures measurement accuracy and reduces the need for frequent replacements of high-voltage relays.
