BT300 Variable Frequency Drive Bypass Options

Siemens is proud to introduce 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.

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

Conventional Bypass
The Conventional Bypass utilizes selector switches and indicator lights as primary functions.

Features:

Advanced Keypad with Start-Up Wizards and Displays
Two Drive Bypass Configuration Options
22 mm Components with Wide Viewing Angle
