Variable Speed DriveStratus drive provides variable speed control of single- and three-phase fans, motors and pumps. The microprocessor-based VFD can be used for temperature, humidity, pressure and flow applications, clean room pressurization, equipment cooling, exhaust ventilation and heating/air conditioning systems. The drive operates from a 115 or 230 Vac single-phase power supply and has on-board programming that allows the setting of many parameters. Output power is 3 A for three-phase motors and 4 A for single-phase motors. Motor speed can be based on several control inputs including control signal (4-20mA, 2-10VDC), temperature (thermistor), 0-18 Vdc transducer or Modbus communication link.
