AL405 DC system ground fault tester
Implementation of standards].
GB4706.1-1998, DL/T475-2006
Product features:
1, Simple, just turn the power switch can be used directly, without another key operation.
2, safe and reliable, no charger, and all other power, has no effect on the DC system.
3, for multi-voltage, DC system 220V, 110V, 48V, 24V can be used.
4, for a wide range of power plants, substations, mines, chemical plants and other electricity sector can be used.
5, easy to carry, signal receiver comes with batteries, no external power supply.
6, uninterruptible power search take place, does not affect the system work properly.
7, anti-interference ability, to overcome the impact of distributed capacitance of the system.
8, intelligent charge management, reduce the charging time, longer battery life.
