BT300 HVAC Drives
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.
The BT300 comes standard with unique and industry-
leading 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.
Designed for HVAC
HVAC demands are unique to other drive applications.
The BT300 is singularly focused on the needs of
HVAC variable flow systems:
• Built-in wizards for start-up and easy setup of
advanced functions
– PID Start-up Wizard
– Multi-pump Wizard
– Fire Mode Wizard
• EMI/RFI filters to meet EMC Immunity IEC 61800-
3 first and second environment.
• Integrated DC bus chokes equivalent to 5%
impedance.
• BT300 Thin Film Capacitors do not require
conditioning. Immediate drive replacement is
possible.
• Standard Integration Protocols (APOGEE
