Power Factor
PFR 96
Digital Power Factor regulator
The digital controller PFR96 can manage up to 12 independent batteries, a communications port, and two current inputs in size from 96×96 framework. Particularly easy to program thanks to a basic configuration with two parameters and advanced that allows the advanced user the most complete of the power factor correction control.
The onboard logic allows corregegre setup via an erroneous wiring of the picture as to or stage of TA.
10ms sampling of the voltage allows the calculation of the RMS voltage continuously, identifying network holes and temporary interruptions and detach the active steps immediately to the protection of the contactors and benches.
The PFR96 can handle numerous alarms associated to available relays.
The means of intervention in the PFR96 adjustment are all customizable for a better quality of the intervention as well as the use of different banks can be equalized for less wear of the contactors.
Sampling at variable frequency and RS485 communication for remote control (PFR96 Plus) complete a range of services offering maximum control and quality of the measurement
The PFR96 includes in itself all the major features for a complete and efficient controlle power factor correction:
- Sampling 10ms (8,33ms 60Hz) voltage and definition of the RMS value; vital for the protection of the network from unwanted holes or insertions
- No need for rewiring with faulty CT connection
- Multilingual backlit display
- Programmable alarms and associated with measured quantities
- Ability to set the maximum level of harmonic distortion of the capacitor current
- Automatic mode and related section
- Parametric intervention mode and user-configurable
- Maintenance Alerts
- Sampling variable frequency for maximum reliability as far as cosphi
- Static relay outputs zero-crossing
- RS485 communication with Modbus RTU protocol (PFR96 Plus)
- Additional input for the measurement of the current of the power factor correction system
- Terminal block with safety screws
Fields of use
PFR96 natively includes Elcontrol analyzers power and quality of measurements:
- Voltages RMS
