This device is used for detecting AC/ DC voltage. With a control voltage level from 5 to 1000V, a red-light indicator for hazardous voltage is visible at all angles, a bright display with large figures for voltage reading and a dedicated display for each function.


The Low Voltage Detector allows the following functions to be implemented on both indoor and overhead installations:

  • Check for the proving dead operation
  • Control voltage levels from 12 to 1000V
  • Discrimination AC/DC
  • Polarity test on DC voltage
  • Discrimination phase / neutral
  • Phase indication (unipolar)
  • Phase rotation
  • Continuity check
  • A functional self-test is performed which turns on all LEDs and emits an audible signal


  • The new generation of display, ultra-bright
  • High-brightness LEDs, visible in full light and indirectly
  • Cable with double insulation silicone: robust and highly flexible (no memory effect), length 1 m ~
  • Display up to 1000 V
  • Lightening of the measurement point
  • Protection without fuse: The device can be used in case of overvoltage
