UNITROL® 1020 automatic voltage regulator

Selected technical data

  • Configuration of digital inputs and outputs (12 inputs from which up to 8 can be configured as output)
  • Configuration of analog inputs and outputs (3 inputs, 2 outputs)
  • Configuration of digital inputs extension using free analog inputs (up to 6 additional digital inputs)
  • Display of measurements, alarms and limiters
  • Real time clock and SNTP synchronization with a time server

The easy to use commissioning and maintenance tool CMT 1000 for Microsoft Windows allows simple adjustment of parameters and easy optimization. It also offers monitoring, advanced trending and downloads of data- and event-logger registers.
