  • 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...
  • Works as supposed to

    Very small. Works flawlessly. I use it in my truck to change the speed of a Webasto petrol heater water pump. I run it at about 60% of original speed and the power width modulator does not get very hot. I have been using it for one season and it still performs as it always has. The price is fair.
    Good quality power width modulator. Works as promised.
  • 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.
  • Very good

    Cheap, come with connectors and dissipate the heat very well.Barato, vem com os conectores e dissipa bem o calor.
    Very nice speed controller for fans, I use it to control a 120x120mm fan.Muito bom, uso em um cooler 120x120mm.
    Very nice speed controller for fans, I use it to control a 120x120mm fan. I used to use a regular 10K ohm trimpot to vary the speed but it burned ... :). Need to dissipate a little heat.
