KDZD900 DC ground fault tester based on the premise of system safety, according to the requirements of industry standards, in a reliable low-frequency signal way to detect, and a lot of practical applications in the field, no impact on the system.

1. Simple to use, the DC grounding fault tester can be used directly by turning on the power switch without other key operation
2, safe and reliable, this instrument does not need to stop floating charger and all other power supplies, no impact on the DC system
3, applicable voltage levels, DC system 220V, 110V, 48V, 24V can be used
4, wide range of application, power plants, substations, coal mines, chemical plants and other power supply departments can be used
5, easy to carry, the signal receiver comes with a battery, no external power supply, you can carry to find the ground point
6, the DC system is constantly powered to find the ground point, does not affect the normal operation of the system
7, strong anti-interference ability, to overcome the influence of the system distributed capacitance
8, intelligent charging management, reduce charging time, extend battery life
