1. Things to be aware of with your new Speed Controller The controller has limited protection against reverse polarity If you hook it up incorrectly you may render the device unusable The voltage jumper is set by defaultat if you plan to run 24v 48v you will need to correctly set the jumper Double check all connections before applying power and always turn off the power supply before making any wiring changes Unless you have the Mosfet isolation option the motor is ground to the case chassis Ensure no stray wires brush against the case or that the case is earthed Warranty All controllers are naturally covered by a warranty against defects in manufacturing for one year If there is a manufacturing defect then we will repair it free of charge Unfortunately there are some failures that are not caused by manufacturing defects but are due to motor or wiring issues and problems outside the controller This type of failure is not caused by a fault in the controller and is therefore not under warranty Unless you explain how you consider the failure to be under warranty we have to assume you have abused it or DC MOTOR CONTROLLER Connecting the Speed Control The connections to the speed control are straight forward Just use the illustrative diagrams on the next page for your reference It is beneficial for currents over 25A to utilise both of the terminals even applying li2. nks between the connections helps but make sure your wiring is capable of carrying the current your application requires or the links will serve no purpose While it is not necessary for operation of the Speed Controller its always good practise to add a fuse between the Positive Battery and the motor Use a fuse rated slightly higher than the current your motor draws The speed controller works by switching the negative terminal of the Battery to the Negative input of the Motor very quickly PWM It does not change the voltage at all i e if your supply input is 12V then your output from the Speed controller will also be 12V regardless of the motor speed setting This is a more efficient way of varying a resistive load like a motor without losing torque or efficiency User Manual Please make sure you to the voltage range you plan to use You may need to adjust the start position when you change the voltage VR2 If the motor makes an audible noise you can lessen or remove this by adjusting the frequency trim pot VR3 until the noise is reduced or gone If you have any queries regarding your new controller please feel free to contact your place of purchase for help and support In standard form this speed controller is NOT insulated meaning if you have the case earthed on a common ground the controller will be constantly on and will not vary the speed This is due to the metal case used on the controller ac
3. ting as a bridge The voltage jumper is by default s If this is not the voltage you need Always add wire links as shown if the current is above 25 Amps This helps carry current for loads greater than 25 Amps Speed Control Connections 1 Motor or HHO Negative Terminal To the Motors Negative connection 2 Link to 1 to help carry high currents shown above 3 Link to 4 to help carry high currents shown above 4 To the Battery Negative Terminal 5 Positive goes to the Battery Positive Terminal This can be a thin wire it s not a load carrying wire This shows the internal connections and adjustments of the speed controller O O Potentiometer O Or Throttle Positive Battery Negative Battery l bia Negative Battery vR2 Start Position Motor Negative Motor Negative VR3 Freq Adjust 12 24V Jumper 24 48 48V Models Only This is looking at the controller case internals Please note On the 12 36V controller the highest voltage is 36V only the 12 48V Version will go up to 48 Volts Note that on standard controllers 40V is the uppermost limit After this point the standard controller will fail
