Description
SRT-010 DC Motor Speed Controller allows the user to control the speed of a DC motor using a PWM (Pulse Width Modulation) and also allows the user to select a working time interval. The timer can also be disconnected and used as a regular controller.
TECHNICAL PARAMETERS:
Input supply voltage: 5V-15VDC
The maximum output power: 30W
The maximum output current: 2A
Duty cycle adjustable: 0%-100%
Controller total size: 41 x 26 x 24mm/1.6”x 1”x 0.94” (including bracket)
PCBA size: 36 x 20mm/1.4”x 0.8” (can be use without bracket “panel mount” type)
OPERATING INSTRUCTIONS:
1. Connect DC power and DC motor (or DC load) to the four terminals on the connector exactly as indicated on Wiring Diagram picture #3.
2. Rotate the blue speed potentiometer knob clockwise until you achieve the required motor RPM. The clock dial on the bracket can be used as a reference target. The LED will be Green indicating power is ON.
3. The controller is equipped with a timer which can be operated through the potentiometer in two different modes:
Mode 1: When timer is OFF. Red timer potentiometer switch is OFF.
Mode 2: With timer ON follow Step 1-3 below.
1. Rotate the red timer knob clockwise using the clock dial on the bracket as a reference. Adjustable timer is not linear. It is recommended to use the Dial Position Reference Table in picture #2.
2. Rotate the blue speed potentiometer knob clockwise until you achieve the required motor RPM. The LED will become Green.
3. When the time interval is expired the motor will stop and the LED will become Red.
SPECIAL ATTENTION:
1. THE TIMER CANNOT BE CHANGED DURING ROTATION OR WHEN THE GREEN LED IS ON. Time interval can only be changed when the blue speed potentiometer knob is switched off.
2. Adjustable timer is not linear. It is recommended to use the Dial Position Time Reference table in picture #2.
