Bipolar expansion valve controller

EVDRIVE is a range of drivers for the management of stepper bipolar valves.
Models for bipolar EEVs come in 4-DIN format, both in a blind version or with built-in user interface (with graphic LCD display and 6 keys),
The drivers can manage both generic electronic expansion valves and the more common stepper valves on the market; they can also be used as a simple analog positioner and can work both on a stand alone basis or managed by an EVCO or third-party controller (thanks to a variety of available communication ports), guaranteeing an increase in the efficiency of the refrigerating circuit.
Some models for bipolar EEVs can have optional Wi-Fi connectivity to enable remote monitoring and interaction from the EPoCA cloud system.
