Unstoppable power.
The BT300 VFD with Conventional or Electronic Bypass: One compact design,
two bypass options, and non-stop coverage for demanding HVAC environments.
An increased focus on energy efficiency
of variable flow systems has increased the
need for easy-to-use and highly reliable
Variable Frequency Drives. Facilities need
devices that help reduce installation time
and maintenance costs, while maximizing
energy savings and optimizing occupant
comfort. Additionally, half of today’s drive
specifications require bypass functionality.
To meet these growing needs, Siemens is
introducing the BT300 Variable Frequency
Drive offering with Conventional or
Electronic Bypass options.
The BT300 VFD with Conventional or
Electronic Bypass is designed with the same
sophisticated and industry-leading features
of the BT300 VFD. This provides peace-of-
mind to customers in mission critical
facilities.
The Conventional Bypass utilizes selector
switches and indicator lights as primary
functions.
The Electronic Bypass utilizes internal
control boards that act as the brains and
eliminate the control wiring, relay logic, and
terminal blocks. They are replaced with
advanced built-in features that are
accessible from an electronic keypad.
VFDs with Conventional or Electronic
Bypass are built for North America and
assembled in the USA. Integrating the same
sophisticated features and easy-to-use menu
structure found in a BT300 VFD makes the
installation and commissioning of a BT300
VFD with Bypass quick and easy.
The BT300 VFD with Bypass
ensures the HVAC equipment at
mission critical facilities runs
continuously and efficiently.
– Laboratories
– Data Centers
– Airports
– Hospitals
On-board Ethernet – Lead the way
with the first VFD with bypass that offers
on-board Ethernet. All standard HVAC
protocols are ready for “out of the box”
installation. Ethernet and RS-485
connections are included for APOGEE®
P1, BACnet IP and MS/TP, Modbus
RTU/TCP, and Metasys N2. Since
communication is built into the drive,
there is no need for a cabinet, power
supply, converter, or extra cabling.
This saves time during installation.
5% Impedance with Harmonic Filters –
Protect against distortion, especially
in sensitive areas, such as laboratories,
data centers, airports, and hospitals.
Seismic Certification – Meets
International Building Code 2012
Standard for confident coverage of
critical systems after a seismic event.
Rugged Housing, Compact Footprint –
Helps lower shipping costs, makes
installation easy, and ensures long-lasting
performance in demanding HVAC
environments.
Diagnostic Board – Allows the drive
to continue to run while servicing the
bypass. Easily accessible test points
enable troubleshooting of the bypass
components and their functionality
while energized. A fusible link prevents
electrical damage to the bypass circuitry.
Safety Switch – While in bypass mode,
the drive can be replaced without
de-energizing power to the driven
equipment. There’s no need to remove
fuses or fuse blocks and no equipment
down time when replacing the drive.
Reduce installation time and maintenance costs with either option:
