Full of merits by integration

  • Small and light
  • Convenient for mobility
  • Easy handling at work
  • Great cost performance – reducing management cost such as calibration
Full of merits by integration

*1)DCFT identifies defective panels in a string, not disconnected points of each panel.
*2)DCFT checks insulation by measuring ground resistance for protecting the device and securing safety of operators.

Identifies defective panels

DCFT measures 1)by string 2)by panel.

Example

No need to measure panels one by one thanks to checking between P-N-GND
