Control the speed of a DC motor using a 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-328-DS. The Soft-Start option slowly ramps up power to reduce stress on power supplies and mechanical linkages.
4 Ways to Control:
- 0V - 5V analog voltage level
- Digital Mode:
- Push Buttons - UP and DOWN buttons buttons to control speed
- Logic Mode - pulse the UP or DOWN lines to change speed
- Silent PWM switching frequency for quiet operation
- Analog or Digital Modes selectable via jumpers
- Digital input filtering allows smooth control even with noisy inputs
- Logic Controller Enable input
- Low Impedance, Long Life filter capacitor for maximum reliability
- High efficiency MOSFET design and Heavy-Duty Heatsinks for cool operation
- 28 Amps continuous current
- 5.5 - 30 VDC operation
- 18 kHz switching frequency
- PWM Range: 0% - 100%
- Single direction (no reverse)
- Terminal blocks for signal and power connections

When choosing a controller based on your input voltage requirements,
please note that a fully charged 12V nominal lead-acid battery can reach 14 volts.
Please check to ensure that the battery pack voltage does not ever exceed the absolute
maximum rated voltage of the motor controller.
