Power factor controller 18 step – multicomp
Overview
The multicomp F144-3Ph-…-3 reactive power controller automatically works in 4-quadrant operation (generator operation), i.e. even with return feed into the energy supplier network, missing compensation power is detected and compensated without any problem. Through the integrated temperature measurement input, the ambient temperature in the reactive power compensation unit is also monitored, and if a predefined limiting temperature is exceeded, the ventilator is switched on. Through the three-phase recording of voltage and current, not only the usual three-phase compensation is possible, but also single-phase compensation or a combination of single-phase and three-phase compensation.
Product detail
