Works fine

Used it to vary the speed of a home-made 240v workshop extractor fan. Works well

Caution: Sensitive To Vibration

I used this to control an angle grinder motor on a prototype machine, it worked well, scaling the voltage nicely and enabling more control, however I mounted it with hot glue on the grinder housing, the vibration after one day of use fractured the solder on the main circuit, resulting in arcing between the connections and frying the PCB. I resoldered this but the potentiometer began arcing heavily and the entire device is now wrecked.For the price, it's brilliant, but make sure you be protect it.

Worked no problem.

I haven't decided what to use it on. I tested it on a small motor and it worked ok.

Decent

A bit loud when not fully on/off. Built in potentiometer allows for the lower pwm limit to be set, allowing for items which would drop out at low pwm to be set at a safe minimum.

TOO SMALL

TINY UNIT TRIED IT ONCE DID NOT WORK . I THINK IT WAS FOR A SMALL POWER

Heat sink gets too hot

I used this to control a 1500 watt heater which is 6amps at 246volts AC the unit controls the heater well but the heat sink on the PCB gets far too hot and I burnt my fingers on it when the output was 500watt. With my design knowledge this is over 60c it should be 25c max "worse value" I consider this to be a fire hazard and I cannot see this lasting long at this temperature. When the scr/triac core temperature runs at 125c the tag on the device should be kept at 25c. So bad design don't buy. Heat sink should be 4 or 5 times bigger in. size. This unit must go in a metal box as it gets too hot. My guess is this was designed to work on 110volts not 240volts the heat sink should not get this hot.

Worked OK after I had re-soldered a 'dry' joint

Ottimo

Preso per gestire un vecchio trapano stayer ad 1 velocità che ho piazzato su un supporto a colonna. Funziona perfettamente. Ovviamente Bisogna montarlo in una scatola adatta, quindi bisogna avere anche qualche abilità nel bricolage

Perfecto

la verdad que es muy completo y de precio está muy bien, si me preguntáis si lo recomendaría, la respuesta es sí, sin dudarlo, tanto por precio como por calidad de todo, espero ser de ayuda si estáis pensando en comprarlo.

Fà quel che può

È quasi un SCR..diciamo un potenziometro o un tiristore...diciamo che è un circuito con un triac.Comunque è carino da vedere ma non aspettatevi troppo.In ambito 230v trova posto come variatore di tensione e può essere collegato solo a carichi resistivi e assolutamente no a carichi induttivi (pena la fusione del terminalino) ; ha un campo d'azione limitato e si nota la funzionalità a partire dal 60% al 100% del campo .Personalmente l'ho cablato per regolare la velocità di due turbine aria ambiente di una stufa a pellets con scheda madre acciaccata da una sovra tensione.Il risultato è apprezzabile ma non eccellente (come era atteso)..insomma non è certo un inverter.Infine un consiglio: il giocattolino và bene per dimmerare le luci,variare i giri di un piccolo motore 230v (es un ventilatore) e basta.Non và bene per utensili che hanno bisogno di potenza (es un trapano o un utensile multifunzione) in quanto al diminuire della tensione diminuisce parecchio la coppia meccanica.Consigliato per usi amatoriali e didattici.Buon acquisto.

NO REGULA EL VOLTAJE DE SALIDA

La salida siempre es de 220v, igual que la entrada. Sin embargo hace regulación PWM, por lo que si permite regular la velocidad de giro del motor, pero de otra forma.
