20 H.P. 480 Volt Type-1 VSD Series Variable Speed IntelliPass Drive (Johnson Controls)

Product Description:
Introducing Johnson Controls
VSD Series Variable Speed IntelliPass/
IntelliDisconnect Drives powered by
• enclosed control and
circuit breaker technology from
•s electrical business.
The IntelliPass bypass is a two- or
three-contactor design utilizing 24V DC
contactors and power supplies. The
features, function and form allow the
drive and bypass to become an inte-grated
design, the world
•s smallest
drive and bypass package. The Intelli-Pass
bypass comes standard with a
Cutler-Hammer circuit breaker inte-grated
into the drive and bypass

Features & Benefits

• Compatibility with current and
future Johnson Controls network

• Supported by standard Johnson
Controls ordering, estimating, and
project management tools: Advanced
Order Management System (AOMS),
Advanced Installation Management
(AIM) Tools
• QUICKLIT, Catalog,

• Closed-loop control programmed
with engineering units for specific
Heating, Ventilating and Air-Conditioning
(HVAC) applications:
duct static, building static, pressure
control, and temperature control

• Run permissive damper control in
drive or bypass mode

• Up to 6 user-defined skip frequencies

• User-selectable S-Shaped accelera-tion/
deceleration curve

• Selectable AI Min/Max/Averaging

• Digital inputs can be defined for
normally-open or normally-closed

• Quick and easy non-HVAC specific,
standard application to get the drive
up and running

• Automatic fault display captures
16 drive operating parameters at
time of fault

• Solid-state motor overload relay
provides motor protection while in

BYPASS selector on keypad
simplifies control

• Two power sources for control
ensure redundancy and provide
additional ride-through capability

• Weighs 70% less than other bypass
designs which simplifies and speeds
up the installation process, lowering
• costs

• Serial communication interface can
control both the drive and all bypass
features so that the remote operator
can fully control the motor whether
it is operated by the drive or bypass

• Plenum rated

• Standard 3% line reactors for
enhanced transient and harmonic
distortion protection

• EMI/RFI Filters standard on all drives

• Top and bottom conduit entry for
installation ease

• Standard drive current rating of
100 kAIC, bypass rating of 65 kAIC

• Pass-through I/O capability

• Lockable disconnect in OFF position

• 3rd Contactor drive isolation option

• I/O and communication cards pro-vide
plug and play functionality

• Copy/Paste keypad function allows
transfer of parameter settings from
one drive to the next

• Keypad can display up to three moni-tored
parameters simultaneously

• Standard TYPE 12 keypad on all drives

• Drive programming capability
using auxiliary 24V power supply

• Standard option board configura-tion
includes an A9 I/O board, A2
relay output board and a B5 output
board which are installed in slots A,
B and C respectively

• Programmable Automatic Restart
• choose from disable;
automatically transferred to Bypass;
reset drive only; and reset drive and,
if fails, then transferred to Bypass
(IntelliPass only)
