The main function

Tuner can be used when the digital frequency meter or voltmeter. The starting voltage is automatically given, the unit shutdown process by frequency decompression, when the frequency is lower than 46HZ into the low-frequency work, and 35HZ automatically de-excitation. Prevent rotor over-current.

Overload protection: When the circuit breaker trips, the voltage is automatically adjusted to 380V. To prevent the machine over-voltage. At the same time because the trip, the generator is still a voltage, so the protection mechanism can be action, such as: off the water machine to prevent runaway and so on.
