The HAU is a single coil proportional valve driver that provides precise control of a single coil proportional valve.
The HAU can be tailored for use on low current EDC valves such as Sauer-Danfoss™ 90 series or up to 5 Amps and enables the user to add ramping and/or dither to minimize stiction and hysteresis of the valve. The HAU comes standard with terminal strips or the optional Weatherpack connectors.
