Low Voltage PWM Brushless DC Controls Application Information • Extended 2-year system warranty when a Bodine gearmotor/motor and control are purchased together. • Drives 24V Bodine brushless DC motors and gearmotors. • To be mounted in separate enclosure supplied by user. • Rated for +50° C ambient (max). • Requires a 24 VDC power source. • Output voltage is up to 95% of input voltage. • 20kHz PWM switching frequency. • Commutation is 60°. STANDARD FEATURES • 24 Volt power requirement makes this control ideal for portable, battery operated applications or applications when safety standards dictate a low operating voltage. • On-board speed potentiometer for manual adjustment. • Accepts 0-5 VDC analog signal for remote operation. • Unique Smart Reverse™ circuit provides quick reversing and prevents motor plugging. • Dynamic braking for quicker stops. • 12 pulse/revolution tach output provides indication of motor speed. • Logic output indicates control shutdown due to a motor overload. • Speed can be adjusted manually or by remote control over a range of 30:1. • Inherent closed loop system maintains a 2% maximum change in motor speed from 0-100% of rated load when operated at rated speed.
