Variable Frequency Drive, 480V, 5HP (4 kW), NEMA 12, Disconnect

The BT300 Variable Frequency Drives (VFDs) are singularly focused on meeting the demands of today’s HVAC variable flow systems. Standard unique and industry-leading features include:

• Motor Switch Ride Through – enables motor maintenance without stopping or tripping the drive
• Thin Film Capacitors – eliminates the need to condition or reform capacitors before applying power
• View/Monitor nine user-selectable parameters at one time – chooses the parameters for their applications
• Smallest Type 12 footprint on the market – lower shipping cost and easy installation

Highly reliable VFDs, the BT300 reduces the cost of installation and maintenance while maximizing energy savings. Integrated harmonic filters reduce noise and interference, and eliminate the need for additional filters and reactors. Two built-in PID controllers provide fast and accurate process control. The BT300 VFDs are easy-to-use with an intuitive graphical display and built-in wizards for start-up and easy setup of advanced functions.

The BT300 HVAC Drive supports Siemens Industry's long-standing, industry-leading backward compatibility tradition to SED2 installations. The SED2 to BT300 Migration Kits include all the components necessary to mount a BT300 quickly and easily in place of an existing SED2, and provide an ideal solution to moving the technology forward at the lowest possbile cost.
