Facility Managers Say...
► “As the U.S. HVAC Market Leader
and the world’s largest manufacturer
of Adjustable Frequency Drives, I
know that ABB will be here in 10
years time and beyond. This is the
most important guarantee you can
give me.”
► “With ABB’s standard built-in
hardware like the 5% swinging
choke and the EMI / RFI lter, I
know that any sensitive equipment
in my facility will not be adversely
affected by drive operaton.”
► “I love the Help button. I call it
my panic button – it quite simply
is always available to guide me with
useful information.”
► “The Maintenance Assistant is
another great feature of the ABB
Drive. I simply do not need to worry
about when it is time to service the
equipment. The drive tells me when
it is time to send people to perform
maintenance.”
Peace of Mind
Wide power range
from 1 to 100 Hp, @ 208/240 V or 2 to
500 Hp @ 380/480 V, covering the vast
ma jor i ty of HVAC applications.
Built-in EMI/RFI lters
The ACH Series Drive meets
the EMC product standard
EN61800-3 for the 1st Environment. These lters eliminate the
need for any additional external
ltering hardware.
Built-in timers
External timer circuits are
no longer needed. Built-in
timers - utilizing the realtime clock - allow starting
and stopping the drive or
changing the speed according to the time of day
or night. Relay outputs can
be operated with timers to
control any auxiliary equipment on site.

N2, FLN and Modbus
embedded
Commonly used HVAC eldbuses are embedded into the
memory of the drive, ensuring
that they are always there if you
need them. ABB has a long history in building automation, with
more than 400,000 installed
drives utilizing serial communications.
LonWorks and Pro bus
LonWorks, Pro bus and other plug-in
modules t under the cover of the drive. A
single twisted pair avoids great lengths of
conventional cabling, reducing cost and
increasing system reliability.
UL Type 1
Built-in!
Swinging reactor - up to 64% less
harmonics
ABB's patent-pending swinging choke means
the ACH Series Drive reduces harmonics by
up to 64% at partial loads when compared
to a PWM AFD with no chokes. There is no
need to oversize the supply choke.
Pre-con gured HVAC
application macros
14 different HVAC application
macros are pre-programmed
into the HVAC drive. Application macros for supply and
return fans, cooling tower fans,
booster pumps and condensers are available, just to name
a few. The user can create two
additional application macros,
selectable manually or through a
digital input. To illustrate this, the
user can create "summer" and
"winter" application macros and
select between these according
to the time of the year.
A Contractor’s Point of
View...
► “With the Hand Macro, I can move air to
dry out the new construction paint and
drywall mud without calling for a certi ed
start-up. There’s no need for multiple
trips to my job site by the ABB start-up
Engineer to commission the drives, and
that saves me money.”
UL Type 12
The motor can deliver full
output at 40 °C - shouldn’t the
AFD do the same?
ABB's HVAC drive is rated for continuous operation to 40 °C with full
current, without being compromised
by temperature variations within any
24-hour period. Full circulation is
available, precisely when needed
- usually, when it is hot outside.
Similarly, Type 12 units can be
operated without the need for derating up to 40°C. And, at 50°C, only
10% de-rating is required for both
UL Type 1 and UL Type 12.
► “UL Type 12 enclosures keep the drive
electronics free from drywall dust and debris during the construction process.”
► “ABB ACH Series Drive enclosures are
UL Listed and UL Plenum Rated. I can
mount the drive in most locations without
worries.”
► “I don’t have to search for external com-
ponents like timers and PID contollers
and then worry about their compatibility.
It’s all there, in the drive”
