Isolated PWM AC Chassis

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.

• NEMA 4x enclosure: Compact, easy to mount, black plastic enclosure.
• Isolated inputs: Accepts floating or grounded signals 0-10VDC, 0-5VDC or 4-20 mA
• User adjustable calibration pots: Minimum speed, maximum speed, current limit, acceleration, deceleration, slip compensation, boost, zero set, brake current, and brake time.
• Diagnostic LED’s: Power, fault, and torque limit
• Stopping modes: DC injection braking or coast (jumper schedule)
• Adjustable 4 to 16 kHz switching frequency; Quiet motor operation or reduced electrical noise.
• Quick Disconnect terminal block: Allows up to 200% torque to overcome intermittent peak loads.
• Additional features: Auto or manual restart after low input voltage fault (jumper selectable), line fusing, enable and direction inputs.
