From 0.7 inductive to 0.7 capacitive
Starting current setting (C/k)
From 0.01A to 3A for the RVC controller
From 0.01A to 5A for the RVT controller (optional)
During operation, RVC (RVT) controller displays:
− the number of active outputs
− the inductive or capacitive power factor
− the alarm conditions: target cos ϕ, over/undervoltage, THDV, overtemperature
− the demand for switching on/off a capacitor step
Without reactors: less than 1.5 W/kvar
With reactors: typical 5.5 W/kvar (7 W/kvar maximum in worst case)
