Review: all good thanks - all good thanks
Review: Taig Micro lathe DC motor setup - I am using this Drok 115VAC to 24V 20A variable power supply, along with a YaeTek 24V DC 350W Permanent Magnet Electric Motor, to drive my Taig Micro II lathe. Considering this whole kit cost about $80 I'm very happy with the result. While not perfect, the value is so high I have to give it 5 stars. If you've been thinking about one of these motors for your micro lathe I say, go ahead! If you are running the 115VAC Marathon motor that Taig sells, then you know about that motor. It's OK, but the speed range with the 4 step pullies is 430 RPM to 1725 RPM, pretty high for larger parts. And it's big, heavy, and kind of brutish - there is no way you need that much power, nor can it even be transmitted with the stock belt. This DC motor setup runs well down to about 5 volts/570 RPM, which is a lathe speed of 140 RPM. It will go a lot slower, but it sounds a bit notchy. It's happier above 5 volts, and I usually have it set about 16 Volts, which makes a lathe speed of 450 RPM to 1800 RPM. The power supply goes to 28 volts and the motor is spinning at 3200 RPM. This PS has been flawless in this application. It is the voltage regulated only model. Using a "Kilowatt" meter I'm seeing up to about 120 watts in my application. So, about 5A at 24V. The PS seems perfectly happy, and the fan has never turned on. Judging from the motor whine while running the lathe there is a very minor variation in RPM with no load, just a few RPM or small fraction of a percent speed. Under cutting load I've not noticed any significant speed change - it does sound like the system is working harder but that's normal. The motor has plenty of torque for this application. At 7V I have no trouble machining 2" diameter aluminum at a no drama SFM. Once again, the belt is the limitation. The only negative for me is the motor is kind of loud. It makes an ever rising pitch and volume whine as RPM increases. I only use this lathe for occasional small parts, so the noise doesn't matter. If you are doing production, it might get tiresome. Who knows how long it will last. Considering it's intended use as a scooter motor I'm hoping with this very light lathe duty it will last forever.

## Features

- 【Volt Adjustment】 Input Voltage can be 110V or 220V. Wide adjustable output Voltage range: DC 0-24V. This supply is suitable for 5V 9V 12V 24V devices. The voltage precision is 0.1V. Note——The maximum current is 20A. But the actual current is depended on the load. No matter how many voltage is adjusted, the current is 20A and can not be regulated. It can be used to device of 2A 3A 5A 10A 12A 15A 20A. Make sure to use the devices which is below 20A.
- 【Hareware】 This Buck Converter is equipped with LED screen, heat sink and cooling fan. The LED screen can clearly display the output voltage. Heat sink and cooling fan can control the temperature in a safe range. During the running power is high, the cooling fan will automatically activate with little noise.
- 【Easy Operation】 This supply is no need to install, after connecting wire, it can be used to adjust output, which is convenient. The potentiometer is inset into the supply. Only to rotate the potentiometer can adjust output parameter.
- 【Protection】 Over Load Protection, Over Voltage Protection, Short Circuit Protection, which can protect your device from damage. Note: the default input voltage is 220V, before using, please switching the input voltage to 110V/220V according to your city voltage.
- 【Wide Application】 This power supply has variable application. It can be used as a 5V 12V 24V power supply for RV, Car, Labtop, Computer, Lab, CCTV, etc. All of our item has 1 year long time warranty guarantee.

### ⭐⭐⭐⭐⭐ Cheap alternative to a benchtop supply.
*by A***G on 1 November 2025*

I got this to kind of use as a benchtop supply. I had a variety of DC motors I needed to test, at a variety of voltages and power ratings. They were intended for battery powered applications, but I didn't have the variety of batteries I would have needed to test them. I looked at actual benchtop power supplies, and they all seemed to top out at about 10 or 11 amps, and were much more expensive. Before ordering this, I hadn't seen anything like this before, although they look to be pretty common. I also bought some leads that I connected to it to make it easy to connect and disconnect what I am powering. It worked perfectly. Provided the voltage range and current I needed and one of the motors, was 24V DC and drew 17.5 Amps, which this provided with no complaints. While I do appreciate the Voltage indicator as a rough guestimate of the voltage, probably "good enough", I did hook up a more accurate meter to set the voltage during my testing. It was easy to get it to within a few 10ths of a volt, but getting it much finer than that took a very delicate touch, but with patience, I could even get it to the hundredths and once there, it would hold it. I see they have another model where it has both voltage and current limit adjustments, and I am thinking I might pick one of those up too.
