  • Excellent product

    posted by carlosnavarro

    small and efficient. Easy to use. excellent for motor control speed. I Use it in my project for educational univercity. I received it faster. The price was very good, but it's a shame that has increased. I pointed to several friends and encouraged his purchase.
    Involving a box would be great.

  • Pricey but good controller

    posted by 13557

    Good small motor PWM controller work with 6V(4xAA battery pack) so it is good for small projects :)Nice looking and fit for many motors.Good screw terminal connectors buy a crimping tool for easy connections on those RED,YELLOW,BLUE insulation connectors :)
    Good PWM
    Love the unit. Hate the price.If only it could be radio controlled for remote controlling possibilities. Please make one with RC control...
  • Very small motor regulator

    very small , PWM , does not need further cooling in my situation.The knob is the biggest part.three skottky diodes parallel in the outpoutline give good protection against back EMP from DC motors and are able to use it with 500 type DC motors or even heavier.
    TRhe 9KHz makes it usable to reguylete the output of Synradlasers (CO2 60W) with RF exiters.Reduce for this purpose the outputvoltage to 5 Volt and draw some current by using a resistor, 5Ohm /5 Watt will do, the signal for the Synrad can bet taken from the powerresistorterminals
    Usable for many applications.Do not use them connected with transformers, the secondair can give a nasty shock.
