DC 6-60V 30A PWM DC Motor Speed ​​Controller

Doesn't work. I have returned the goods.

I put it in a clear top waterproof box (Junction Box - TOOGOO(R) Clear Cover Plastic Electronic Project Junction Box 100 x 68 x 50mm), with the variable resistor mounted in the top; this is OK because my motors can only draw a small fraction of 30A.I successfully drove a motor from 5V 4A power supply and from two 3.7V Li-ion batteries in series, about 7.4V.The only defect I could find on mine was "the top right segment of the right-most 7-segments digit was not lighting up", but it's OK, because I can easily deduce the digit, so I've spare deduction of a star, on this occasion.One gotcha I found was that even switched-off, in the above sealed box, there could puzzlingly occasionally be some power still on the output, which caused frustration and even when some stuff to break. I eventually noticed that a large IC near the transistors seemed to have moisture between its one row of legs, possibly condensation, so I dabbed them with dry tissue and sprayed some light oil over the board to prevent reoccurrence. Ideally, conformal coating, or some other clear coating, should be applied for water resistance.

Fa egregiamente il suo lavoro, molto buono il display incluso con la percentuale di velocità che è rosso e ben visibile. Peccato manchi la scatolina poteva fare la differenza.

objet hors du commun.

Perfecto

Ich habe diesen PWM-Motorregler gekauft, um den defekten Stufenschalter für das Lüftergebläse meines Toyota Landcruiser durch eine stufenlose Regelung zu ersetzen.Die Platine wurde innerhalb von zwei Arbeitstagen geliefert und ist sauber verarbeitet. Kleines Manko, sie kam ohne technische Dokumentation (Anschlußplan), aber die vier Klemmen sind eindeutig beschriftet, man kann nichts falsch machen.Der Einbau war einfach, die Platine erfüllt einwandfrei ihren Zweck.
