The 40A specification is highly overrated, the controller would melt at that current. At most 2.5mm^2 wires can be attached to it which is good for maybe 20A and the PCB seems to be also strong enough for 20A. There are 6 transistors which all have adequate cooling so no problem here either (maybe with some fan attached to cool them for longer periods of usage). The issue are the most likely the two 330uf/63V capacitors. These get very hot when the regulator is in use and the regulated device not running at full performance. I was testing peltier module (12V, 20A at full performance)... which was running fine at maximum current (unlimited)... but we don't need the controller for this, right. However at approximately 75% performance - 12V, 15A the capacitors got very hot (60+°C ) after 5 minutes of operation, probably would get even hotter if running longer. And there is a high toned pitch, probably coming from the capacitors. I don't think it is save to use this for such high current, and even if it didn't blow up, the capacitors would degrade quickly. I guess for current up to 10A this regulator is good to use, maybe more with some modifications (like replacing the capacitors for better low ESR ones) this would allow load of mor than 10A. Still, for the money it is not bad, good PCB design and soldering, just not very suitable for high load.
وصلت في حالة جيدة مع بعض أجهزة تتبع لطيفة جدا على ظهر السفينة. تريمبوت لديه نقرة لطيفة جدا عليه! أتطلع إلى تركيب زورقي!
Rigtig fin motorhastighedskontrol, den skal bruges til en ældre golf vogn og fungerer efter hensigten.
Perfect for a project that I am working on
منظّم جيد، حسنٌ، أبني صندوقاً جميلاً بفتحات التهوية.
مطابق للوصف
