- Filtered DC output for cooler motor operation, longer brush life, lower audible noise, and wider speed range.
- Dip switches to easily calibrate control for different motor sizes.
- Line voltage and temperature compensation minimizes speed drift.
- NEMA 12 enclosure for environmental protection.
- Trim pots on PC board to adjust torque limit, minimum speed limit, maximum speed limit, acceleration time, and speed regulation.
- Speed can be adjusted manually using speed pot mounted on enclosure.
- Terminal block inside enclosure for quick line and motor connection.
- Back EMF feedback maintains better than 2% speed regulation.
- Fuse holders for line and motor inside enclosure (both fuses supplied).
