Twin Turbo: Expansion Mode for CMC 430

The CMC 430 is the ideal three-phase relay test set for currents up to 3 x 12.5 A in situations where maximum portability (8.7 kg) and a robust design are required. The release of Test Universe 4.10 and new accessories once again represents a significant expansion of the test set’s application area.

The new Expansion Mode enables two CMC 430 sets to be connected via the device-specific expansion ports. One of the test sets can then be configured as an amplifier very easily in Test Universe so that up to 6 x 12.5 A can be output via the current channels. The use of two CMC 430 test sets in tandem is an attractive new option for anyone needing a flexible testing solution for a very broad range of applications:

  • Combining two CMC 430 sets provides 6 x 12.5 A, e.g., for testing transformer differential protection
  • The GPS-synchronized operation of two physically separate CMC 430 sets enables both devices to be controlled from a single application using RelaySimTest testing software

Learn more about the additional testing possibilities for the CMC 430 with the update to Test Universe 4.10.
