15 Amp DIGITAL High Frequency PWM Motor Speed Controller

The SPD-315-D is a low cost brushed DC PWM Motor Speed Controller. Input options allow the use of a potentiometer, 0-5V signal, push buttons or logic pulses from a microcontroller or PLC to set output pulse width. This controller features a silent PWM switching frequency for use in noise-sensitive applications.

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:
• Potentiometer
• 0V - 5V analog voltage level
• Digital Mode:
• Push Buttons - UP and DOWN to control speed
• Logic Mode - for PLC's and Microcontrollers - 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 noise filtering
• 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
