PBwel is the leading designer, manufacturer and supplier of quality electrical safety products.



This device is used for no-Voltage Testing of direct current overhead lines (mainly transport overhead line: trams, metro, trains).

  • Detection of DC voltage (presence or absence of voltage)


  • Setting the threshold by self-learning on real voltage (MCU)
  • Robust shell with flexible adapter coupling (AFLEX).
  • Full auto control with self-test button (cable is also tested)
  • Warning excess voltage range (> 4000V) visual and continuous sound indication.
  • A current limitation in the cable below <3.5 mA.
  • Surge resistant up to 36 kV.

Technical Specification

  • Double voltage indication, powerful sound and a flashing light indication.
  • Presence of real DC voltage indicated by audible and flashing high-brightness
    red light
  • No voltage is indicated by green high-brightness light.
  • Self-check incorporated to ensure the correct functioning of the device in the field before and after use.
