Prophi reactive power controller
The intelligent controller for the future-proof compensation system
The Prophi reactive power regulators have a patented Control behavior to operate each capacitor stage with the same number of switching Switching cycles and the same operating times as far as possible. This significantly extends the service life of the overall system, thus reducing subsequent investments over many years.
Typical areas of application:
- Automatically controlled power factor correction
- Choked power factor correction
- Harmonic filter
- Voltage stabilization by means of dynamic BLK
- Mixed operation (hybrid circuit) contactor and thyristor switch
- 12 or 13 switching outputs
- Extended measuring voltage range (up to 760 V ~ L-L)
- Control of inductive compensation systems possible
- 20 pre-programmed control series
- Control series editor
- Full graphic display 128 x 64 pixels
- Menu navigation in plain text
- 4-quadrant operation
- Automatic initialization
- Display of various network parameters
- Display of harmonics
- Display of THD-V / THD-I distortion factor
- Monitoring of the capacitor current
- Storage of maximum values
- Storage of switching cycles and switching times
- Manual / automatic mode
- Zero voltage switch-off
- Various fault messages / alarm relays
- Fault memory
- Test run of the system with fault analysis
- Control of inductive compensation systems possible
- Voltage, current, frequency, active, reactive and apparent power
- Voltage harmonics (up to the 33rd / even up to the 16th)
- Harmonics of the current (up to the 33rd / even up to the 16th)
