Variable Speed Drives 

Close up view of the variable Speed Drives product familyThe use of variable speed drives in HVAC systems gives building owners the opportunity to increase energy savings.  Often, many local utility providers will offer rebate incentives to businesses for installing VSDs as well as high-efficiency motors.  EMC Services has found the JCI drive an excellent fit for many customers.

The JCI Drive is compact making it the right choice for many retrofit applications with limited space.  The intuitive start-up wizard is accessible through the keypad with easy navigation and display make it a cinch to get drives up and running.  The wizard features the most commonly used motor nameplate parameters in order to simplify set-up.  For the first time in a variable speed drive, the sensor actuator (SA) bus is now built into the drive - no option card is required!

The major types are:

  • Micro Drive - a cost-effective solution for small motors up to 10hp.
  • Open Drive - one of the most popular and cost-effective models, plenum rated, available in enclosure class Type 1 or 12, from 1 - 250 hp.  These drives do not have a bypass.
  • Intellipass / Intellidisconnect Drive - similar to the Open Drive, this model adds a disconnect or a bypass.
  • Enclosed Drive - for the more rugged environment, the Enclosed Drive is offered in Type 12 or 3R, has a standard input circuit breaker.
