With the advancement of power detection and communication technology, as well as the development of big data, Four-Faith intelligent LED fault indicator can work under 3A current, perform fast fault detection within 20ms, and support power line clamping, through 3 different color LEDs The light change prompts the fault information, which is clear in the daytime of 100m and the night of 500m, which greatly shortens the time and scope of fault finding. LED Fault indicator is our unremitting pursuit to help you quickly restore the power supply.
Permanent fault, transient fault and low battery alarm can be distinguished and indicated by 3 different super bright flashing LEDs respectively. And a ground fault can be indicated by two alternately different super bright flashing LEDs. The fastest fault detection time can reach 20ms
up to 10 years
The JYZ-HW indicator can be powered online through the built-in current sensor. LED Fault indicator only needs a line load of more than 3A to start, and the service life can reach 10 years.
Four-Faith's own intelligent algorithm and special current sensor, the current detection accuracy of JYZ-HW fault indicator can reach ±1% in the load line of 300~800A, which helps to accurately judge the occurrence of fault
Hot Stick Mount
Using the indicator adapter with the hot stick installation, it supports the installation of the indicator without power failure. The unique design supports the installation directly on the ground.
