Eae pessoal, hoje um review de 02 produtos que vieram do site Banggood da china, não escolhi os mais baratos mas sim os que aparentavam ter maior qualidade e não me arrependi em nada, pois além de cumprirem com o que prometem têm um ótimo preço. Vou utilizar o Dimmer na minha CNC router para controlar a velocidade da tupia pois dependendo do material é melhor usinar com velocidades menores.

This unit controls the amount of time AC sine wave voltage is applied to the target. AC is in the form of negative and positive sine waves, 50 -60 times a second. If you measure the voltage output, you probably won't measure much of a voltage change, as this unit controls how long sine wave voltage is applied to the unit you're trying to control. For example, at low output, sine wave voltage may only be applied, 30% of the time, whereas at full output, voltage is applied 100% of the time. These units work well with resistive loads, they work well with universal motors ( brushed motor used in grinders, drills, saws etc). Universal motors have tremendous torgue but their speed control sucks, so you will be able to slow your grinder down, but it will not maintain the speed you select, under load. Motors like treadmill motors require DC voltage, so you would need to connect a bridge rectifier between the output of this unit and your treadmill motor. In between your motor and bridge rectifier, you should install a choke (5.5mh ?) to reduce voltage spikes that may, eventually damage your motor. You should ground the box of this unit.

....i bought it recently...but the main input label was on the fused side rather on a heatsinked side...does it matter,,?..it still worked either way anyway,,.i got confused since the reading on the multimeter on the output side did not change as i turn its pots...falsely advertised to output 10ACV-240ACV ....it was the Am;perage or the wattage that was variable...there was no manual or guarantee on this....confusion on this is possibly viral...but i am glad i learned something and able to share my experience ...Cautious when dealing with mains ...tested on incandecent for scavenged washing machine motor control experiment..i did not feel like this a few days ago...

Amigo você está ligando errado, OUTPUT e SAIDA

[@ricardoramos4086]

Só dele em 220v.... Não tem pra 110v ou Bivolt desse mesmo modelo. Os outros que são Bivolt sâo mais limitados porque não tem desse modelo. 😒

Grinder close and running full speed loose on table!!! Next video is about woodworking with only 3 fingers on one hand.

[@madeiraemetal]

Diminui a velocidade. Também diminui o torque? Se diminui o torque fica impossível cortar um monte de coisas.

[@AlanHerrigCreations]

O dimmer diminui a voltagem, então consequentemente tem perca de torque, no video eu usei uma exmerilhadeira de 2000w então mesmo que eu abaixe a velocidade ainda tem força suficiente para lixar. Pra ter pouca perca de torque tem que usar um inversor de frequência, só que ai estamos falando de um equipamento de mais de mil reais...

[@brazilcreative1063]

is this dimmer AC or DC current?

[@petertyrrell6690]

AC

[@djmazola]

Amigo,o dimmer funciona em 110 volts?

[@ishanmadushanka3709]

can i use this for 0.75 Horse power water pump motor ..please reply

[@petertyrrell6690]

These units will not work with regular induction motors , but. If you unit has brushes, this controller may work with it

[@silviu8672]

my dimmer makes a buzzing noise and the drilling machine makes noise to

[@petertyrrell6690]

When kind of motor does your drilling machine have? Does it have brushes?

[@silviu8672]

Hi My drilling machine has a cable for power input 220 v ,50-60 hertz

[@petertyrrell6690]

@@silviu8672 your drilling machine would require a Variable Frequency Drive (VFD) to properly control its speed, if you continue to try to control its speed with the type of unit shown in this video, you'll "smoke" the motor. An induction motor such as yours, requires frequency control as well as current control to properly manage speed, and this is what a VFD does.

2फेस मोटर में चलेगा

[@petertyrrell6690]

If your motor is a universal type, not an induction motor, then it will work.

[@naturesnr]

Hi, you are luck. i get 3 pieces. all is out 220volt only :(. trash i get.

[@petertyrrell6690]

These units control the amount of time sine wave voltage is applied to the target device so you may not measure much of a voltage change. Try connecting a light bulb to your unit's output, you should be able to dim it.
