Variety of Motors: Permanent Split Capacitor (PSC), Shaded Pole, Synchronous, and 3Ø Induction
Torque Foldback: Allows up to 200% torque for short periods to overcome intermittent peak loads, then reduces the torque to a (preset) safe level
Adjustable Switching Frequency: Default 16kHz frequency can be changed to 4k, 8k, 10k, or 12k Hz using kit 202-0108. Higher frequencies result in audibly quieter motor operation, but lower frequencies produce less electrical noise and may prevent GFI tripping.
Diagnostic LEDs: Power, Torque Limit, Fault (Undervoltage, Overvoltage, 250% Current Limit Trip)
User Adjustable Calibration Trim Pots: Maximum Speed, Torque Limit, Boost, Acceleration and Deceleration
