The Phase Lock Loop hydro controller formerly built and sold by Carson Electronics is now available as a free public domain design.

An LCD screen and 5 LED lamps display the plant's operational status, including load management, extra power currently available, and water control (the ">" in the corner of the screen means the controller is "increasing water" to the turbine).

*If you have a PTC-3 trail counter with Serial number prior to 10101314, hang onto it - these units have roughly double the battery life of current units (estimated at up to 10 years). A change in design of the LCD display, done by the display manufacturers apparently in response to the discontinuation of a part they were using, has led to increased power consumption of the PTC-3.
