BT300 HVAC Drives
Siemens Industry, Inc.
Figure 1. BT300 HVAC Drive without
and with Integral Disconnect.
Description
Siemens Industry's BT300 is designed specifically for the
demands of today’s HVAC systems. Increased focus on
energy efficiency of variable flow systems has increased
the need for easy-to-use and highly reliable variable
frequency drives that reduce the cost of installation and
maintenance while maximizing energy savings.
Features
• Motor Switch Ride Through – during maintenance the
motor disconnect switch can be opened and closed
without stopping or tripping the drive.
• Thin Film Capacitors – eliminate the need to condition
or reform the capacitors before applying power.
• View/Monitor nine parameters at one time – User
selectable, users determine the parameters for their
applications.
• Smallest Type 12 footprint on the market – lower
shipping cost and easy installation.
• Standard Integration Protocols (APOGEE
®
P1,
BACnet, Modbus, Metasys N2).
Typical Specifications
This specification covers a complete Variable Frequency
Drive consisting of a pulse width modulated inverter
designed for use on a standard NEMA Design B induction
motor:
A. All VFDs shall have the same customer interface
regardless of horsepower rating.
B. Input voltage shall be 208 to 240 Vac, 380 to 500 Vac,
and 525 to 600 Vac +/- 10%, 3-phase, 48 to 63 Hz.
C. VFD shall have integrated DC bus chokes equivalent
to 5% impedance.
D. Base VFD shall be UL listed for 100 kA SCCR.
F. All circuit boards shall be coated to protect against
corrosion and meet IEC 60068-2-60 Method 1.
G. VFD shall utilize built-in wizards for start-up and easy-
to-set-up advanced functions, such as PID, Bypass,
and Fire Mode.
H. VFD shall have a "favorite" feature to allow the end
user to create and save custom settings.
I. VFD shall have Ethernet IP, and RS-485 port as
standard.
J. VFD shall include EMI/RFI filters. The entire assembly
shall be CE marked and meet EMC Immunity IEC
61800-3 First and Second environment, and EMC
Emissions to meet NE61800-3 (2004) Category C2.
K. Keypad shall be able to display and monitor nine
parameters simultaneously.
L. VFD shall employ thin film capacitors and require no
reforming or conditioning, allowing for a shelf life of 10
years.
M. VFD shall have a motor disconnect switch parameter
which, when enabled, shall prevent the VFD from
tripping when the motor disconnect switch is opened
and closed allowing for easy maintenance.
