NEW BERLIN, WI, Summer, 2004 - A comprehensive profile of the full range of features and benefits built into the new ABB drive for HVAC applications, the ACH550 series, is showcased in this new brochure.

Meeting Users Where They Are
The unitary controller built into the drive, along with an explanation of how BACnet compatibility is loaded in as an option, and the drive's built-in second PID loop all are showcased for Temperature Controls Contractors. And separate, additional pages describe similar benefits for Contractors, Facility Mangers and Consulting-Specifying Engineers.
Cell Phone Keypad and Reduced Harmonics at Partial Load
The drive's user-friendly control keypad, modelled after a cell-phone design and utilizing full language (rather than codes), is profiled for all users. New-to-market features that the ACH550 pioneers are described -- such as Maintenance, Diagnostics and Programming Assistants, along with Help Screens and a Help key. The drive offers sophisticated technology made simple -- out-of-sight-and-mind, 24/7 constancy that gives users peace of mind from knowing these drives provide multiple modes of motor control and wide flexibility across the full range of HVAC applications.ABB's patent-pending Swinging Choke design, built into the drive, also is illustrated in the brochure.
The ACH550 drive is uniquely able to reduce harmonics at both full and partial loads, for a total harmonic reduction of up to 30%, compared to traditional reactor designs; and up to 64%, compared to drives with no reactors (estimates are based on a power system impedance of 1%).Fans and pumps operating with a variable-speed drive operate at partial load most of the time.
Significantly reducing harmonics at partial load can help a facility manager keep his or her building in compliance with the IEEE-519 Recommended Practice.ABB is the leading supplier of drives to the Commercial market in the U.S., where they are used in multiple HVAC applications.
Print copies of ABB drives for HVAC applications are available from ABB's exclusive distributor network.ABB Inc., Low-voltage Drives, is the #1 drives supplier to the U.S. HVAC market, and has connected tens of thousands of drives to building automation systems.
In the USA, ABB, New Berlin, Wisconsin, supplies a complete line of energy-efficient electric drives and motors to HVAC and commercial customers through an integrated channel of sales representatives and distributors. Products manufactured include AC and DC variable speed drives from fractional to 500 horsepower.
HVAC single-motor drive applications include exhaust fans, fume hoods, re-circulation pumps, condenser fans; multiple-motor applications include multi-cell cooling towers, paralleled chilled water, and booster pump systems.For information on the new ACH550 drives, specifically, see www.abb-drives.info/ach550/ ABB ( www.abb.com ) is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact.
The ABB Group of companies operates in around 100 countries and employs about 115,000 people. The company's U.S. operations employ about 9,000 in manufacturing and other facilities in 40 states.
