The REGO reactive power controller is designed to control and regulate capacitor banks. It operates on the basis of microprocessor technology, which provides accurate, reliable power factor measurements. The power factor is controlled by switching capacitor banks according to the reactive power requirements of the load. The controller features both automatic and manual operating modes. In addition, the powers associated with the steps can be automatically acquired due to the “Auto Acquisition” function.
Features
- The series REGO controller relays are fully static units controlled by an eight bit micro processor with HC mouse technology
- Self programming function for power stages and operating logic i.e. no need to set C/k setting
- Can check health and efficiency of each and individual capacitor bank connected
- Comprehensive displays with large, three-digit LED display
- 3 logics (1:1:1), (1:2:2), (1:2:4) to connect/disconnect banks, with automatic recognition or with standards programs
- RS-485 Communication
