700BDC/730BDC Brushless DC Motor Control
Dart’s 700 Series of brushless DC motor controls provides variable speed operation for most brushless DC motors. Compact, economical, and ENERGY EFFICIENT, the 700 Series provides the newest alternative in brushless DC motor control. These drives are ideal where high speed or quiet operation is needed, combined with a BLDC motor completely eliminating brush wear. The 700 Series may be provided with a pluggable connector and fixed speed settings for OEM applications.
The 700BDC / 730BDC / 731BDC models are ideal for fan, pump and other basic applications. The 733BDC is suited for those applications where more sophisticated motor speed profile control is needed (ACCEL/DECEL). Model 733BDC has a unique Current Limit Latch feature that allows many options for addressing equipment and personnel safety in overload conditions.
The 731BDC model (only) offers our new Modbus RTU serial interface option. Change speed and direction, monitor speed and system health, profile speed for servo-like response – all these capabilities and now unlocked with the model 731BDC-RTU – call us to discuss your application needs.
