OCTD Testing Equipment

The OCTD testing equipment is equipment that singly conducts testing and inspection of overcurrent tripping devices that control the overcurrent breaker in electrical circuits.The OCTD testing equipment is portable and hence convenient for regular inspection and maintenance of OCTDs, and it operates on commercial AC 100 V input.


  • Singly conducts testing of OCTDs
  • Generates testing voltages including overcurrent conditions with high accuracy
  • Accurately measures the tripping time regardless of its length
  • Has a break function that can temporarily stop the test
  • Has various fail-safe mechanisms to ensure the protection of the OCTD being tested

Touch-Panel to Mouse Converter MPI-K12A

The touch-panel to mouse converter is equipment that converts signals to enable the replacement of touch input from the existing touch-panel monitor with mouse input. It is a labor-saving, high-accuracy converter that allows precise operation from a distance and eliminates fatigue of touch operation.


  • The existing touch-panel monitor can be replaced with a normal monitor
  • Signal cables from existing touch-panel monitor are used without replacement
  • The generation of touch signals is replaced by a mouse
