High Voltage Multiplexer

Durable multiplexer for comprehensive motor testing systems

Ideal for building systems that combine high-voltage testing and 4-terminal low-voltage measurement
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.

Key Features

  • A single multiplexer that lets you consolidate six different tests
  • Safe switching between high-voltage testing and 4-terminal low-voltage measurement
  • Reliable multiplexing design with extended operational lifespan
  • Guaranteed measurement performance and high durability
  • Up to 24 channels significantly reduce connection man-hours and test time
