DC Voltage Sensor Digital Output WB6830R2-P

DC Voltage Sensor Digital Output WB6830R2-P

The WB6830R2-P Three phase electric parameter acquisition module can monitor the voltage, current, reactive power, apparent power, power factor, frequency and other parameters of the power grid, and the operation state of the power grid with wrong phase and phase breaking. It can measure positive and negative electric energy, active and reactive electric energy, four-quadrant reactive electric energy, time electric energy and monthly electric energy; and can analyze the 2~31 times harmonic content of voltage and current, total harmonic content (THD), imbalances of voltage and current & components of positive sequence and negative sequence and zero sequence, the current K coefficient, the voltage wave peak coefficient and so on. The maximum demand for average phase current, active and reactive power and apparent power can be calculated. When using this product, it must communicate through the RS485 interface and according to the specified protocol to get the required digital electrical parameter value.
