| Enhanced Features, CUL Recognition for SmartFan Nimbus AC Fan & Motor Control |
SmartFan Nimbus is a compact, digital fan control designed for the HVAC, electronics and industrial controls markets. Nimbus automatically controls single-phase (PSC, Shaded Pole) AC fans, motors and pumps in applications such as humidity control, room pressurization, equipment cooling, room ventilation, heat exchangers and water circulation.
Nimbus was selected as the winner of the 2003 AHR Expo Technical Innovation Award for Ventilation. Nimbus regulates fan speed from a control signal (4-20mA, 0-10VDC, thermistor). Automatic voltage and frequency detection, current ratings up to 7.5A and mounting configurations including DIN rail and 4x4 job box make this microprocessor-based design extremely flexible and economical.
Recent enhancements to the Nimbus include an on-board pressure transducer option, selectable fixed speed settings and CUL recognition. Benefits of using SmartFan include acoustical noise reduction, temperature regulation, greater product reliability, increased fan life, improved safety and energy savings.

SmartFan Stratus is an economical, yet highly versatile variable frequency drive that provides precise variable speed control of single- and three-phase fans, motors and pumps. Typical VFDs are compatible with more motors, can control to lower speeds, have a more linear control curve and are more energy efficient at reduced speeds than a TRIAC (voltage) based control. This microprocessor based VFD is ideal for applications including environmental control (temperature, humidity, pressure, flow), clean room pressurization, equipment cooling, exhaust ventilation and heating/air conditioning systems.
On-board programming allows the setting of many parameters providing maximum flexibility. Stratus operates from a 115 or 230 VAC single-phase power supply. Output power is 3 Amps for three-phase motors and 4 Amps 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. Special and custom configurations are available. From $99.00 – available now).
Benefits of using SmartFan include acoustical noise reduction, greater product reliability, increased fan life, improved safety, energy savings and regulation of temperature, pressure, humidity or flow.
