multicomp F144-3Ph-…-3 reactive power controller
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.
Highlights
- Detecting and compensating the missing compensation power in case of return feed
- 18 stages for single-phase or three-phase compensation
- Switching of capacitive and inductive stages
- Limiting value monitoring function for the protection of capacitors from overvoltages and excessive harmonic load.
- Integrated temperature measurement input for monitoring the ambient temperature and switching on fans
- Illuminated graphic display 128 x 96 pixel with dimming function
