Product overview
Unipolar 4 Phase 8 Stepper Motor Driver
Electric expansion valves are designed for precise liquid injection in evaporators for air conditioning and refrigeration applications or other applications: crankshaft power limiter, hot gas bypass, evaporating pressure regulator, etc. The valve piston and linear positioning design are fully balanced to provide bi-directional flow characteristics and tight shutoff of the solenoid valve in both flow directions. The driver provides different control logics: 1.) Manual; 2.) Overheat; 3.) Liquid injection for compressor cooling 4.) Analog input
