permanent magnetpotentiometerwith speed control

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 • Operates from 115 Volt AC line. • 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. • Lamp on enclosure indicates AC power on. • Factory installed AC line cord. • Unfiltered drive draws lower AC line current than comparable SCR filtered controls. • Connections for optional user-supplied inhibit switch.
