The INCON® 1250B is a versatile programmable position monitor. Its main application is for Transformer LTC position monitoring, but its non-linear conversion table gives it the ability to convert non-linear rotary motion into a linear scale for additional applications.
With over 40 years of proven service in over 33,000 utility transformers around the globe, the 1250-LTC does so much more than just monitor tap position. It is a vital tool that utilities use to predict transformer maintenance and prevent the failure of their LTC’s.

Displays tap position and transmit this information over analog and serial lines
Works with any LTC or voltage regulator
