SmartFan® Nimbus II – AC Fan Control / AC Motor Control
|
Operation / Installation PDF |
Nimbus II is our 5th generation off-the-shelf 120/240VAC single phase controller compatible with TRIAC controllable fans and motors rated up to 7 Amps. The Nimbus II can be customized for your application using the Navigator hand-held programmer (pictured above). The Navigator can be used to create fan/motor speed control curves based on a control input such as a thermistor (temperature control), a variable voltage source (up to 10Vdc) or current source (up to 20mA). Other programming variables include: on/off set points, alarm trigger points, and startup voltage options. Simply plug the Navigator into a powered Nimbus II and scroll through the 12 variable menus, selecting the control inputs for your application. Programmed profiles can be saved and copied to multiple controllers with ease. Other features added to the Nimbus II include onboard fusing, improved electrical noise immunity, 10X improvement in control loop response and isolated control inputs.
Advantages over the first generation Nimbus controller include:
- Easy menu-driven digital programming ( Navigator required )
- Wider & more detailed programming options for increased accuracy and flexibility
- Save & copy control variables from unit to unit
- Improved electrical noise immunity ( TRCEx00 & TRCC700 only )
- Onboard fusing
- Lower voltage drop at full speed ( approximately 1% )
- Compatible with new S-series tighter tolerance & lower cost temperature sensors
- 10X improvement in control loop response
- Onboard Power / Fault LED
- All inputs isolated for added safety
- Programmable soft start or full voltage startup
- Enclosure option available
CAUTION – SmartFan Nimbus II is designed for OEMs (Original Equipment Manufacturers) and is not intended for end-user or after-market applications. The Nimbus II should only be used with compatible induction motors (Permanent Split Capacitor (PSC) or Shaded Pole) that are approved by the motor manufacturer for TRIAC (voltage) control. Attempting to control a fan or motor that is not compatible could cause excessive heating and/or permanent damage to the motor.
