Product Details

Note: Image may not represent actual item.

480 VAC, 50 HP NEMA 1 VFD with electronic 2 contactor bypass, graphical interface, and fused disconnect Siemens BT300 variable frequency drives are specifically designed for the demands of today’s HVAC systems. The BT300 drives are easy to use, easy to understand and easy to program. The 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. Siemens BT300 Variable Frequency Drives are offered with conventional or electronic bypass options. Electronic Bypass 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.

Features:

  • Advanced Keypad with Start-Up Wizards and Displays
  • Full Bypass Control - even if the Bypass Board Fails
  • Auto Bypass
  • Pass Through I/O
  • Additional HVAC I/O Capability
  • Essential Service
