Reactive Power control relays

The reactive power control relays type RPR are a standard DIN144 door mounting unit. They are available as stock items with 6 or 12 output contacts as standard. All types include digital power factor indication and are capable of switching any combination of capacitor size ratios, depending on the requirements of a particular installation. They are also capable of switching non-integer ratios of capacitors. This enables the exact capacitor sizes in any given application to maintain a target power factor. Further features include optional alarm outputs for failure to reach the target power factor, fan control, secondary target power factor, and harmonic overload of the capacitors. These are available at extra cost on request.
