Description
The Franklin Grid 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.
- Receives a signal from a synchro transmitter (1292 series)
- Provides absolute position feedback
- Displays tap position and transmit this information over analog and serial lines
- Works with any LTC or voltage regulator
- Includes a software draghand feature to report highest and lowest tap position
- Programmable through the serial port or front panel
- Provides an analog output to SCADA or tap controller
