Franklin Electric INCON® 1250B-1-I-M Programmable Position Monitor
The Franklin Electric Critical Power INCON® 1250B-1-I-M Programmable Position Monitor is engineered to provide highly accurate measurements of absolute local and remote transformer load tap changer (LTC) positions. Equipped with a high-visibility 5-digit LED display and an isolated +/-1 mA analog output, this instrument provides network engineers and facility operators with the critical data needed to balance transformer loads, regulate line voltage, and reduce overall power costs.
In addition to standard electrical grid applications, the 1250B-1-I-M has the capability to convert rotational position into a non-linear indication, making it highly effective for specialized applications such as hydro dam gate position monitoring. It is designed to wire seamlessly in parallel with existing synchro transmitter/receiver pairs, or directly to a synchro transmitter.
