The device detects the voltage difference between the operating system and the system to be combined. When the closing pulse is sent, the error of the voltage difference should not exceed ±10% of the set value.
The device detects the voltage difference between the operating system and the waiting system, and the error of the voltage difference should not exceed 10% of the fixed value when the closed± pulse is issued.
The device detects the voltage difference between the operating system and the system to be paralleled. When the closing pulse is sent, the error of the voltage difference shall not exceed ± 10% of the setting value.<br>
