6V – 90V 15A PWM DC Motor Speed Regulator Controller

Description

The DC Motor Speed Controller allows controlling direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0% ~ 100%. The motor speed controller can provide a continuous current of 10A to your DC motor or other DC load.

The circuit also includes a 20A fuse, with reverse connection of power supply and control voltage over-voltage protection function.

Specifications:

• Input supply voltage: DC 6V ~ 90V
• The maximum output power: 1000W
• The maximum continuous output current: 10A
• The overload and short circuit protecting current is 15A
• PWM frequency: 16KHz
• Duty Cycle adjustable: 0% ~ 100%
• The operation environment temperature: -20°C ~ 40°C
• The 20A fuse with reverse connection of power supply and control voltage over-voltage protection function
• Can adjust the speed by an external 0V ~ 5V signal
• Size: 64 x 59 x 28mm

Note:

This can NOT be used to the BRUSHLESS motor.

The speed regulator supports the use of an external DC voltage control (0V – 5V). Using the following steps:

1. Remove potentiometer. (you may take it down from one side of the circuit board or potentiometer side down under your need);
2. Connect 0V ~ 5V DC control signal to the middle pin marked 0V ~ 5V;
3. Connect the earth wire of 0V ~ 5V DC control signal to the pin marked GND;
