Unfiltered SCR DC Basic Speed Control
Application Information
- Rated for continuous operation in 40° ambient with no additional heat sink.
- Drives Bodine 130V Permanent Magnet DC Motors.
- Drives 90V "SCR duty" and 130V "PWM duty" permanent magnet DC motors made by other manufacturers.
STANDARD FEATURES

- Line voltage compensation minimizes speed drift.
- NEMA 1 enclosure for environmental protection.
- Back EMF feedback maintains better than 2% speed regulation.
- Dip switches to easily calibrate control for different motor sizes.
- Two diagnostic LEDs indicate when power is on and when current output is at limit set by TORQ pot.
- Trim pots on PC board to adjust torque limit, minimum speed limit, maximum speed limit, acceleration time, deceleration time, and speed regulation.
- Speed can be adjusted manually using speed pot mounted on enclosure.
- Terminal block inside enclosure for quick motor connection.
- Fuse holder for line on front panel.
- Toggle switch on enclosure to turn AC power on/off.
