DHC-100 DC Digital High-Resolution Controller

Peaktronics DHC-100 DC Digital High-Resolution Controller

The Peaktronics DHC-100 is a high-performing digital positioner used to control AC actuators. It provides 450 points of resolution, with quarter-turn actuators ranging from 2 sec to 120 sec. 

The DHC-100 has features that will improve any actuator and is still to install. It’s interchangeable with the AMC and LRC standard size controllers and can be used to upgrade performance for those applications.
