SmartFan Stratus II VFD (variable frequency drive) is designed to control single or three-phase fractional HP, inverter grade motors via a transducer (voltage or current signal), building automation system (voltage, current signal, Modbus), thermistor, potentiometer, contact closure or Modbus RTU network. This VFD can be customized in minutes using the menu-driven SmartFan Navigator handheld remote programmer or through the Modbus communications port.
For an explanation of the Stratus II variable frequency drive motor requirements and risks, please see AC Motor Compatibility.
For a technical article on how the Stratus II AC variable frequency drive compares to other control technologies, see Controller Comparison & Motor Efficiency.
