⚙️ Master your motor’s speed with precision and power — no compromises!
This PWM DC Motor Speed Controller supports DC 10-55V input with a maximum current of 60A and continuous 40A, featuring a 15KHz PWM frequency. It offers stepless speed adjustment from 0 to 100% via a 100K ohm potentiometer and an LED display for real-time speed percentage. The controller includes a forward-brake-reverse switch and is housed in a perforated aluminum alloy case for heat dissipation and safety, making it ideal for DIY motor enthusiasts and industrial applications.

Good Value
The controller was delivered two days after ordering as promised. I was scepical ay first that the controller could deliver the advertised 60 amps as this is a small package and it has very little in the way of heat sinking. However, there are four RU7088 driver MOSFET transistors in parallel and a 60 amp drain would result in 15 amps per transistor. The specified on state resistance for the transistor is .005 ohms which will result in a power draw of a little over 1 watt which s an acceptable rating for this design. There are two 80 amp relays working in concert to reverse the output. The input/output terminal strip is a bit light for 60 amps of current draw. I connected the controller to a 12volt battery and a load of about 20 amps and it functioned as advertised. The display is only on when the speed control is activated. My assessment is it is well worth the price.

Poor build quality
Error on my part I shorted the pot to ground and burned up a trace. Can’t blame the produce for that. However when opening up the unit to troubleshoot the build quality became apparent. Poor component placement, heat shield still and clear plastic protective coating.. if I attempted to remove the plastic, the terminals labels would have come off as well.. I suppose the good news is I was able to repair the burn trace and the unit is working fine.. at least for now.

Nouveau modèle aérodynamique ??
Emballage intact mais le boitier de contrôle aplati je pense qu'il y a une personne qui a passé une mauvaise journée sur la ligne de montage 🙄

Not good
I couldn't tell how it work. Before installing in a box the broke off the switch. Text the company no answer. You need to up grade the wire size.
