Onyehn DC Motor PWM Speed Controller3V 6V 12V 24V 35V Speed Control Switch Mini LED Dimmer 5A 90W(Pack of 2pcs)

Upon opening the package, one of the boards I received had an obvious open circuit, which did not function. We completed a quick visual inspection and solder touchup, and the board appears to be working fine. In light of this, I used these boards in an unorthodox way I used them to control some computer fans that were running at PWM. Instead of sending a pulse to the fan, as this device was intended to do, output the PWM signal (pin 4) to the fans so there is a linear response to the knob turning in relation to the speed of the fan. The board has only to be powered up via 12V and the fan PWM pin must be connected to the motor- I'm pinn. It is NOT recommended to use MOTOR+ because your fan will be damaged, as the pin is only rated for 5V, Despite the fact that it doesn't quite have the right base frequency, it works flawlessly.

Aside from the small size and ease of mounting, the device has a built-in knob for All power input and output connections are clearly marked and are These will be used in other projects as well.

Although I have not tested bypassing the "max width" setting to see whether power is reduced, I don't believe there is. In this case, the average current consumption drops off as the pulse width is narrowed, which is great for reducing the overall power consumption. The 16aH battery in my fan allows me to run my fan all day long. This controller does not seem to get hot to the touch, and the construction and soldering appear It is important not to put the thin capacitor near the rotary control in the same enclosure as the dial. It can be bent and distorted, so make sure you mount it away from the dial and your fingers.

Install only after it has been bench tested. Dimming action is smooth and there is a wide brightness range. After hooking up the second unit, powering it on, and then turning it on, the circuit board was very hot to the touch and the LED lights started flashing. The first one worked perfectly and was only 80 degrees during the bench test. I measured the temperature within 30 seconds of turning on the machine and it reached 140 degrees. Despite the fact that these bulbs work great for dimming, I am unsure as to whether they are safe due to quality issues at present.

We use the motor to drive a hydroponic system and I wanted to control the output of the motor. I was able to vary the motor speed and thus the water flow for a few weeks with no problems. An accident caused the capacitor to explode one day. To see if I have any luck with the second one, I'm dropping it in. Therefore, be extremely cautious in your expectations and be conservative in your expectations for the current output required and things will probably go well. This was a while ago.

Buying a brushless motor blower from eBay was a good decision. I tried attaching the yellow or blue wire for AC (+) but it wasn't working, searching on Google how speed control was found showed the picture from The power wire (+/-) must be connected to brushless motor blower In the circuit for the speed control switch, add a resistance of 1K OHM and a wire (-) The (-) is converted to a blue colour In the B), theb bought an Amazon speed control switch. After I received it and assembled it, I tested the brushless motors and that they were working, so I feel lucky.

In this case, it is a DC motor controller that cuts the output voltage of a motor by 11 percent thanks to its design. To power an electric smoke generator device that requires between 6 and 7 volts, I must convert the voltage from a 7 volt 3 cell LiPo battery to the voltage I need. In this case, I set the voltage to 6 by using it. You need to charge the battery with five Also, there is no loss in output from the smoke unit. I love it!.
