  • product introduction: is a driver for double pole stepper motors designed to control the electronic expansion valve in refrigerant circuits. It is designed for DIN rail assembly and is fitted with plug-in screw terminals. It controls refrigerant superheat and optimises the efficiency of the refrigerant circuit, guaranteeing maximum flexibility, being compatible with various types of refrigerants and valves, in applications with chillers, air-conditioners and refrigerators, the latter including subcritical and transcritical CO2 systems. It features low superheat (LowSH), high evaporation pressure (MOP), low evaporation pressure (LOP) and high condensing temperature protection (HiTcond) (also for CO2 cascade systems), and can manage, as an alternative to superheat control, special functions such as the hot gas bypass, the evaporator pressure control (EPR) and control of the valve downstream of the gas cooler in transcritical CO2 circuits.
