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.

I purchased the 8Amp 60Vdc (480W) variable voltage/current version.Originally bought this as a bench supply with variable high voltage DC and current limit control.As an experiment, I tried using this to power an upscale treadmill with bad electronics.Its motor was okay, so I needed about 30Vdc at a little more than 8Amps, so it was a gamble.It did not have quite enough current to drive a 2.5 Hp brush DC motor at >crawl speed, but that is not its bad. It was a calculated failure for this application.I have a few other DROK products and they are all nicely functional and high quality construction.I have no complaints and would buy again.One thing I suspect with this particular supply, is its slow response to load current transients, such as would be the case with a treadmill -where footfalls produce velocity changes in the belt and motor drive that in turn induce surges in load and thus changing current draw as the load varies.The supply's display (tested to be accurate) indicated a current hitting >9Amp peaks and could not deliver sufficiently to maintain belt speed.Again, not its bad, just not enough headroom for the intended application.Note that testing at these extremes caused NO damage to the supply. The duty cycle was low enough that the fan did come on but only slow and the case became only warm to the touch.Instead, I purchased the variable 24Vdc, fixed 20Amp (480W) version, which works perfectly at crawl (16Vdc) to brisk walk (27Vdc) speed. Funny thing about some of these supplies is the DROK brand looks the same as the other odd-named (non-DROK?) supplies offered on Amazon. I suspect these may be made in the same factory despite differing brand names.
