Control the speed of a DC motor using any 1k to 30k potentiometer, 0-5V signal, push buttons or logic pulses from a microcontroller. This controller features a silent PWM switching frequency for use in noise-sensitive applications. It can also be used as a low voltage light dimmer for halogen lamps, or for controlling heaters and irons. This controller operates in the same way as the basic digital model (SPD-2115B-ED) but due to the high frequency switching, there is no audible PWM noise. The higher frequency also allows for smoother current in the motor and a higher system efficiency. Automatic Soft-Start is available on P/N SPD-315-DS. The Soft-Start option slowly ramps up power to reduce stress on power supplies and mechanical linkages. 4 Ways to Control: Analog: Use any 1k - 30k potentiometer 0V - 5V analog voltage level Digital Mode: Push Buttons - UP and DOWN to control speed Clocked Mode - for MCUs - pulse the UP or DOWN lines to change speed Additional Features: Silent PWM switching frequency for quiet operation Analog or Digital Modes selectable via jumpers Digital input filtering allows smooth control even with dirty pots Logic Controller Enable input Low Impedance, Long Life filter capacitor for maximum reliability High efficiency MOSFET design and Heavy-Duty Heatsinks for cool operation Specifications: 15 Amps continuous current 5.5 - 36 VDC operation 18 kHz switching frequency PWM Range: 0% - 100% Single direction (no reverse) Connections: Terminal blocks for signal and power connections
