I think your motor was probably vibrating because of the way brushless motors work. That's why they need three connectors. I was switching the wires in a brushless motor to reverse direction with a battery plugged in and it had a similar shaking while only 2/3 wires were connected. The other thing is that you mentioned gallium nitride (GaN) electronic parts. I know that those are generally higher quality and are used in computer chargers like those made by RavPower.

I like that it has the USB c with quick charge and power delivery. That would be a perfect place to plug in a USB c powered soldering iron.

[@PushenShpek]

If the size is an issue you may want to check the MDP-P905 power supply. It's DC powered only and more expensive but it's tiny and also has dedicated on/off button. It works great as a smoke stopper and to calibrate voltage/current sensors in Betaflight.

[@wakscientist7410]

During your motor test I see that the voltage output actually dropped to almost nothing and that was most likely from a protection circuit like a crowbar. The low resistance of the tiny motor coil will seem like a dead short to the power supply, sometimes even if it is within operating ranges. This is perhaps due to the Impedance of the PS becoming larger that the load impedance. or something smart sounding..

[@dextergreenman2162]

I used this cutie, and it is sooo good. No longer use my lipo for soldering. It's so good. The size is great. I hope it lasts longer than my M4Q, that one smelled a bit and now just 3 slots are working.

[@chezfpv9139]

just as a headsup, my hota d6 plus has a power supply capability too. Not sure about the about the other hotas but it helps with stuff like testing components on the bench without having to spend 100 bucks on something like this

[@gus8378]

The ISDT 608AC is less powerful, but it does it too. It's great to not have to use LiPos on the bench.

[@cantifpv669]

Pulse width modulation (PWM) is used in a lot of high amp output power supply. If you had an oscilloscope you would see that when reaching the set limit of the power supply. It's still direct current (DC) but it has noise in the DC output. Being a prior electronic technician that did circuit card repairs, I do have the tools and knowledge to test these speculations you have.

[@dirtfpv]

A DC power supply was one of the first things I bought when I got into the hobby. When starting a new quad I'd set it to 1A and never needed a smoke stopper. I have no idea why everyone doesn't have one. They'll spend money on smoke stoppers but then use a battery to test everything, or batteries of different voltages. I only use my power supply for every quad. I only use batteries to test fly. The power supply was $60. Worth every penny and I use it for WAY more that just quadcopters.

[@TheKiter]

I bought one of these just two days ago. Mainly for powering my gear, quads, goggles, vtx and so forth. But unfortunately I did fry mine in a second 😩. I was doing some current calibration for a little 120 mm toothpick, small motors without props. Under betaflight motor testing everything was quite fine. Pushed the motors to different rpm to read out current for calibration. Input was 12.4 V an 5A limitation. But as I moved my sticks on my transmitter to push the motors, I immediately fried it while cutting throttle all the way down to zero. Within betaflight I slightly adjusted power to the motors and that worked fine. But cutting throttle from high rpm did cause over-voltage I guess and killed my power supply in milliseconds. I am very sure that demage was not because of over current, as it exploded on throttle cut an not throttle raise. Any suggestions? Did you try anything similar? Or anyone else?

[@kluverfpv8243]

Had it for 2 weeks then it exploded 🔥ToolkitRC does not answer.

[@gus8378]

I use an ISDT 608AC as a bench power supply. I love it.

[@MrOrangeman18]

The reason behind this being so small is mainly the size of the capacitors they are using. Bigger more expensive power supplies use big bulk capacitors, and a lot of them to reduce any DC ripple. This thing at high loads like you where testing with the motor will for sure have huge ripple. Some electronic devices arnt designed to accept this ripple. Also this psu can also be used to charge up lithium batteries. No need to plug an additional charger onto it. 👍🏻

[@sml2238]

when you were testing the motor, that is DC, it's the magnets that are likely causing the vibration or perhaps as you said the limiter, but I don't know if the limiter would cause an oscillation or if it just brick walls it at the desired amp limit.

[@gertjanx5205]

Joshua, that's a nice one ! 200W dc. Zo it can do 20V at 10Amp. Very nice! Thanx for the tip! 👍👍

[@TonyLing]

My P200 arrived today, I upgraded the firmware, set the current limit to 0.5A, and tested current limiting. There was a loud bang, and now it does not work on AC. It still works on DC. The AC board shows significant damage including a damaged chopper device and a blown track. I bought it from an Ali-Express seller

[@JoshuaBardwell]

Bad luck :-( Defnitely contact ToolkitRC support and I expect they will replace it.

[@oliverhihn8505]

Very well made video, helped me decide to buy one for myself.

[@licensetodrive9930]

Given how critical the voltage level can be to some devices, especially if you're going to use it to drive 3.3v or 5v things, putting the power-output on/off function on the same dial as the voltage level setting is a very big NO NO. The power-output on/off needs its own separate button that does nothing else.

[@benargee]

I agree but the main power button could have been used for this purpose too. Maybe click, hold or double tap.

[@petrokey]

As Ohm tells - better have higher voltage with less current. Because any wire also has a resistance, and the higher currency we have, the more lose we have on wire. Actually it is the reason why we have cross-town power supply higher voltage then inhouse

[@conniedebeer8058]

the ECS's takes the DC-voltage input and basically chops it and is then electronically controlled and then spits out a varying 3-phase voltage; your motor can use.

[@TonyLing]

5:00 With the current firmware (V1.03) the lower current limit setting is now 0.5A.

[@MCsCreations]

Joshua, I made (built, however you want to call it) a lab bench power supply about 2 years ago... I used a power supply board (which I just forgot the name 😬), one of those big AC to DC power supply that delivers 24v 10a and so on... It can output up to 30v and 5a (150w). And I honestly love it. But, for just this description, you can imagine the size of this thing... Right? 😬 So... I can't buy this one right now, but it's REALLY tempting! This one is only 100w on AC (if I'm not mistaken), but the space on my workbench it would save is fantastic. And I could keep my other one in the shelf for whenever I need it. So... Tempting. Really tempting! 😬 Anyway, fantastic review as always! 😊 Stay safe there with your family! 🖖😊

[@ddegn]

I've had half a dozen bench top supplies through the years. My current favorite cheap supply is: *Tekpower TP3005T Variable Linear DC Power Supply, 0 - 30V @ 0 - 5A* Based on the reviews, it seems like they might have quality control issues but I have two of these power supplies and they always work fine. One complaint about the ToolkitRC P200 is the 1 amp lower limit on the current. I often need to limit current far below an amp. I have several ToolkitRC products and I think they're a good company but I'll pass on the P200.

[@tdanel]

If I'm not mistaken AC to DC uses switches so yea it will oscillate. 120V to 10V it has to open and close so many times a sec that's why it's not a lab-grade bench power supply.

[@sleepyheadfpv1507]

I use my old power supply (computer power supply) from when I used a toolkit and it is just attached to my bench now. Runs my soldering iron and then if I need to power up a build I use the smoke stopper with a little extension on it. Seems to work but this would be awesome to have. Haha

For general home quadcopter usage, I'd suggest people look at the 12V / 10A / 120W laptop-charger-style power supplies on Amazon and then cut the plug off and solder on an XT60. It's really useful if you need to need to power your goggles, a quad or even a small charger at your desk. Much cheaper as well.

[@mab4195]

maybe the ripple is due to the pwm limiting circuit, as you said ;)

[@licensetodrive9930]

Diagnosing USB devices - check out the Mustool UD18, a cheap and very useful voltage & current monitoring puck-shaped device with a nice size colour screen and Bluetooth so you can even monitor it with an app on your Android phone. It has USB-C plug & socket, barrel plug & socket, USB3 plug & socket, plus a micro-USB socket so you can power it with a separate power supply to get a more accurate reading because it then won't be drawing power from what it's measuring.

[@tacticoolnukes849]

I'm not sure if I got a defective unit or just an early batch but I found out that this charger either doesn't have overcurrent protection for the AC input or it's insufficient. I was using it to test my quad and an error somewhere caused the motors to spin up which over currented the AC supply and blew a fet in the unit. The DC supply still worked but the AC supply was toast.

The reason most „proper“ bench supplies are huge and heavy is that they use a transformer and linear regulators instead of switching regulators. The advantage is much less ripple in the output. Whether that’s relevant for the fpv hobby use case... probably not.

[@gbraadnl]

It is relevant for test and measure situations, not so much for RC hobby.

[@johnfaustus1]

You got it backwards - switched mode power supplies (SMPS) is the one you want versus linear power supplies. SMPS (like proper bench power supplies) are bigger, costlier. ToolkitRC was able to keep size and cost down by going with linear regulators.

[@harryjohnson615]

@@johnfaustus1 No, you're confused. Linear power supplies are far superior, very heavy and more expensive with cleaner outputs. SMPS on the other hand are cheaper and lighter but the outputs are dirty. They cause a shit ton of RF harmonics derived from the switching frequency, audio engineers wouldn't be seen dead with a switched mode. Don't get me wrong, there's a place for switch modes but they are inferior to linear supplied.

Check for yourself, set your scope to a low level and start looking at the O/P for switching transients and you will see them better still, if you have a spectrum analyser you can view the harmonics in the frequency domain as well as the time domain.

[@tastenheber]

GaN is certainly nice and all, but the actual advantage in terms of efficiency and size reduction is way smaller than manufactures want to make us believe. It would certainly be possible to build a same sized device with "conventional" transistors. Also there is nothing wrong about it being a switching PSU, but it depends heavily on the build quality (the Ruideng modules many people use, are also switching PSUs). Good switching supplies are even used in better HiFi applications by now. Still, when it comes to lower prices, the cheap chunky ones (using a big and heavy transformer) are more likely to produce a good quality DC voltage.
