Feature
1. Easy to use. The DC grounding finder can be used directly by turning on the power switch without any other key operation.
2. Safe and reliable, the DC grounding finder does not need to stop the floating charger and all other power sources, and has no impact on the DC system.
3. There are many applicable voltage levels. DC systems 220V, 110V, 48V, 24V can be used.
4. Wide range of application, can be used by any type of power supply department such as power plants, substations, coal mines, chemical plants
5, easy to carry, the signal receiver comes with a battery, no external power supply, you can carry it anywhere to find the ground point
6. The DC system continuously searches for the ground point without affecting the normal work of the system.
7, strong anti-interference ability, overcome the influence of system distributed capacitance
8. Intelligent charging management, reducing charging time and extending battery life
