Features The panel is simple, the function is clear, and it conforms to the ergonomic design. To meet the application requirements in various scenes, and it can operate reliably in harsh environments. Voltage current protector can automatically reset with no manual operation, easy to use and very convenient. With accurate voltage test, the undervoltage protector does not exceed 1% of the overall range. Protection device will not be damaged by the maximum overvoltage of the circuit failure.
