Function characteristic
Liquid crystal display or LED shows three-phase voltage, current, active power, reactive power, power, power, power factor and power network frequency, control parameter, etc..(utilize this series of continue rollers to assemble the capacitance case or compensator can save ampere meter, voltmeter, universal change-over switch, etc.)
Strong anti-interference ability can resist 2000V interference pulse from power direct, and not crashing, does not lose the data, it is reliable to run steady.
Reactive power control physical quantity, high control precision;
The user can revise the control parameter according to his own need, the control parameter is not lost to have a power failure.
With automatic discriminating phase function(sampling signal automatic be kept in the same state).
The input resistance of current sampling signal is smaller than 0.05Ω; it can be taken out from measuring loops directly.
With over-voltage, under-voltage, imperfect phase protective function.
Compensation mode: phase splitting compensation, phase splitting slipping compensation and
three-phase compensation, the three-phase compensation.
Output mode: static state, dynamic state, compound etc.
