The PR1-P propeller regulator control and keep constant the engine speed by varying the propeller pitch.The use is very simple: you set the desired engine RPM and the PR1-P will do all the job, displaying the target RPM and the actual RPM measured from the engine. It is completely adaptable to the characteristics of various propellers thanks to settable parameters that permits to obtain the maximum regulation accuracy.
Thanks to its patented hardware and software, PR1-P can mantain the target RPM with a precision of +/- 20 RPM, just like a propeller with hydraulic governor.
PR1-P and PR2-P are the only regulators that can be used on very fast propellers (propellers with regulation time from min to max pitch in 2~3 seconds).
