The LLI-1500DC is made for use in determining the voltage status of DC live line systems. This makes this an ideal product for use in mass transit railway (Metro) and tram-based applications and it is mainly used on overhead lines to test for voltage presence but can also be used on third rail installations.
When the conductor being tested is live, the LLI-1500DC indicates voltage presence by the use of visual high intensity flashing LED lights and an extremely loud 70dB alarm will also sound.
This version of the LLI-1500DC is suitable for use on system voltages of 1500V. There are also two other versions of this device available which are suitable for use on 750V and 3000V DC systems.
The LLI-1500DC has 33% threshold setting for system voltage. This system also ships with a star wheel adaptor that can be used to connected to other operating poles.
