Hahiyo 10-60V Low Voltage DC Motor Speed Controller Smooth Linear Adjustment Knob Compact Units Reduce Heat Module Dimmer Switch Regulator 1 Pieces for Mini Fan Electric Pumps LED Light

About this product

*Good linear control:These little units allow very smooth control of the pulse flow,which is also nicer than the typical “low” or “high” options.The recently installed fans to keeping your 3D printer cool but only problem is the fans might be too loud.Use this and now instead of the simple 1-2-3 speed control you can have a full range of speeds,dial the fanspeed down to a noise level that is tolerable.

*Smooth functioning knobs:The build-in knobs has a very smooth transitions.The speed control only effectively uses a single turn of the knob to adjust from off to full on.They will work nicely for you to use it to control an electric fuel pump on a small engine the 0 to 100% feature give you the ability to tweek the pump curve for the perfect air to fuel ratio.It also has a detectable “click” when unit is off.

*Compact and neat:Well designed and manufactured.This unit is small and compact, and mostly easy to work into a motor system.Nice little add-on for just about any small motor driven project.You can easily hide it under the base of a 3D printer.The module’s clean footprint and the thermal management of the output transistor is adequate,no noticeable problems under 1 amp 100% duty cycle at 12V DC.

*Easy to install:Instead of building your own,these boards are cheaper than the price you could get for just the components needed,all gussied up on a circuit card already.The wiring directions are printed on the board itself,so you don’t have to guess.Clean solder connections with adequate heat sink,once it was set it provides a nice range of control of the motor.

*Multi-Function:Work well with a water pump and allows you to be able to control the voltage to get the appropriate pump output.Also good for slow some gear motors down for a diorama.They will work perfectly to control the speed of the blowers you have pushing fog out of your homemade humidifiers.They can fulfil the job to lower the voltage on some strings of old Christmas lights to prolong the bulb life.
