multicomp D6 reactive power controller
The multicomp D6 reactive power controller works automatically in 4-quadrant operation (generator operation), i.e. even during energy recovery to the energy provider network, missing compensation power is easily detected and compensated.
Through the integrated temperature measurement input, the ambient temperature in the reactive power compensation system is also monitored and if a predefined limit temperature is exceeded, the fan is switched on. The multicomp D6 reactive power controller also has an interface for connection to the KBR eBus, whereby all settings can be conveniently carried out from the PC (without the display module). In addition, the bus communication can be switched from KBR eBus to Modbus RTU/ASCII.
Highlights
- Fast control behavior by switching several steps at the same time
- Advanced mode for power generation plants (generator mode) by selecting different Q-regulations: Q[U], Q[P], Q[AI], Q[DI (max. 16 digital inputs)]
- Remoted main current measurement (by using multimess D4-1) incl. summation of several measuring points to total Cos-Phi
- Detecting and compensating the missing compensation power in case of recovery into the energy supplier network
- Network analysis and limiting value monitoring function for the protection of capacitors from overvoltages, overcurrents and excessive harmonic load
- Two-line LC display with stage status and recovery
- Integrated temperature measurement input for monitoring the ambient temperature and switching on fan if limiting values are violated
- Modular up to 24 stages
- Prepared for control of an analog compensation stage
- Available in two language packs: DE/EN/FR or EN/ES/PT
