Stepper motor control

SMS14

For controlling electronic (expansion) valves such as those used in air conditioning systems and heat pumps. Compatible with unipolar and bipolar motors with 500 or 1000 steps. Control takes place using PWM via one of our controllers, as does the 12 V supply. As a safety device, three supercapacitors (5 F/5 V) can be connected to guarantee that the valve will close if there is a power failure.
