DRIVES AC & DC Variable Speed Drives - 1

Variable Frequency Drives Bison's variable frequency Drives feature a lightweight, plastic NEMA 4X enclosure, an isolated front end, minimum speed adjustment potentiometer (pot), output voltage doubling, DC injection braking, and automatic or manual restart when power is restored. Compact Size: 4.3" x 3.7" Easy to mount in small spaces with industry standard mounting hole pattern. Easy to Calibrate & set up: On board trimmer pot adjustments for boost maximum speed, acceleration, Torque "foldback' feature: Allows up to 200% torque for short periods to overcome intermittent peak loads, then reduces the torque to a preset safe level. 16kHz switching frequency, with option to change between 4 and 16 kHz in the field: A high switching frequency results in quiet motor operation.. Adjustments to a lower frequency if desired can be Everyday, engineers around the world poke, prod, weigh, test, analyze and generally dissect our products. ...Not that we mind. At Bison, we build all of our products using one simple philosophy: it's what's inside that counts. We have been defining gearmotor Robusticity™ Of course, it doesn't hurt to offer the industry's best service and support either.

DRIVES AC & DC Variable Speed Drives - 2

Bison's SCR speed controls are dual voltage drives that can control speed or torque. When torque mode is selected, the functions of the speed and torque pots change. The external potentiometer sets the torque reference, the on-board torque pot sets maximum speed and the on-board Max Speed pot sets maximum torque. Dual Voltage SCR Speed Control Speed Range and Regulation: 1 % regulation over 50:1 speed range. 1 % regulation over 60:1 speed range with the addition of a tachometer for feedback. 4 Quadrant Reversing: Regenerative / 4 quadrant drives have the ability to perform quick,...
