- Testing the Hi-Link HLK-PM01 5V 600mA 3W power supply module - load (max current), ripple and safety test.
Dummy load & battery analyzer circuit diagram: tefatronix.g6.c...
/ tefatronix
I will use them for relay driver board, which is anyway live and inside a plastic enclosure. For IOT final product, these are great. But for development and testing, I will use isolated lab power supply.
The maximum output current was 0,60A?
Yes, because it is a 3 Watt power supply. >>>>>> 3 W / 5 V = 0.6 A
800mA at 5V with some ripple, officially 600mA.
What would you consider better? Does it dissipate heat easily when used within specs?
Hey nice instrument there, Can you please make video on how you made your adjustable load
Thanks. I do not plan to do so anytime soon, however here is the documentation on my website: tefatronix.g6.cz/display.php?page=batmeter&lang=en
Congratulations on the video. The electronic load is very interesting, by chance can you share the project of that electronic load? thank you very much
Thank you! It's here: tefatronix.g6.cz/display.php?page=batmeter&lang=en
@@tefatronix The electronic load seems wonderfull. thank you for sharing. Is there any update on load project??
@@abdulkadirgozuoglu8946 Thanks, and sorry for taking so long to reply. I do not plan to update this exact load project due to some non ideal design choices, which would require too many hardware modifications. I might (and would like to) create a new version in the future and post it on this channel, but sadly there are other unfinished projects and other priorities.
is it normal to hot?
Hey bro! I purchased two pieces of that module (same ratings 5V 3W) for my iot based project. To verify the stable voltage I made a resistive circuit to flow my required current let it be 200mA . I placed a resistor of 5/0.2 ohms and when noticed the current it was in the range of 0.14 to 0.16 and the strange thing was that the voltage was 4.4V and little bit fluctuating.. why was that? When I saw your video it was like wth is going on in this world?? 😕
Hi, sorry, I can't tell you exactly what's wrong with the module. Theoretically it should be fine with any resistive load having 8.33 ohms or more. The module may be defective or counterfeit - try contacting the seller, they might send you another one or refund you.
Dear friend, for this module still get needs? This is Bonnie from Hi-Link, now we upgrade the new modules. More to discuss if any chance.
Can we use this to power an Arduino board by connecting the output pin to the Arduino's VIN?
Definitely can be used to power an Arduino. If you have a standard 5-volt Arduino, you can connect it directly to the +5V rail (if it's going to be the only power supply, alternatively if you are going to use several power supplies - e.g. connect the Arduino to a PC while it's connected to the module, etc - insert a schottky diode like SS34, SS14, 1N5819... between the module (+5V out, Schottky anode) and the Arduino's 5V rail to prevent any power from getting back to the module - may not be necessary and will drop voltage by around 0.2V, but might provide a small extra safety margin. Some Arduinos already implement similar circuitry.)
Thank you TefaTronix for the info.
Can you use 2 of these wired to give a plus and minus voltage?
Yes, there should not be any problem with using two modules to get a symmetric output.
However, if there is a risk of shorting the -/+ outputs together, or just to be sure, I'd add schottky diodes like 1N5819 antiparallel (cathode to +) to the outputs of the individual modules.
can i use for long team product with esp8266 nodemcu ????? can this run up to 1year continues?????
Hi, you probably can, I haven't done any long term tests with this module though. But people are generally happy with those modules and I don't recall them having stability issues, burning out, etc.
Mine it's on for a month h24 on esp32, without problems
Yes, you can. I'm using it - always on from 2.5 to 3 years now. Stable product as long as the load is less than 400mA.
@@vinaysathyanarayana7598 So probably just for the mains AC detection with 5V out for MCU that should be good and safe?
Hi, i wanted to ask that can I use this to power my NodeMCU and 5ch Relay board directly with the mains line??
Is their any risk or suggestion while using this??
Hello, this module is designed for such purposes. If you don't exceed the maximum current (600 mA, or to be safe, let's say 75%) it should be fine. I found out that the module I got was of decent quality, but of course I can't guarantee that all of them are going to be original/good quality.
can I use this for AC voltage sensor
Presence/ absence of AC or measure AC voltage? You can never measure AC voltage with this.
Can i ask you if the -vo and +vo have connections. Because when i check my hi link with multimeter there connection between it . And my project will be short circuit
Hi, I am not sure, as I don't have it on hand now. You can test it out of circuit (carefully). But if you are just measuring it with no power, you will likely measure a diode drop (0.15-1V likely) on diode mode on the output in reverse and/or some parallel resistance (more than hundreds of Ohms).
@@tefatronix OKay thanks
Komponen in eagle?
Can I use this output to power a 5VDC coil relay? Should I use any additional circuits for long life. ?
If you are switching a relay directly, there should not be any issue (unless you have a relay so huge that it exceeds the maximum current).
If you are switching it using some transistor, IC... then use a protection antiparallel diode, looking for "relay protection diode" online should give enough results.
@@tefatronix Thank you 👍
Can you indicate the noise level, on the scope we do not see the range used?
Hello, sorry for the late reply. I made this video a long time ago, and probably don't have any more measurements/documentation related to this module other than what's in the video.
can i use that for like charging my lead acid battery that rater at 70AH so its 0.7A and from this its going to throttle at 1A and my question is how do i use it?
Hi, this module is not really suitable for that use.
@@tefatronix well okay thanks dude back to laptop charger or some other adapter with a buck converter
Hi, is it stable as to directly feed a MCU without adding any additional voltage regulator?
Hi. I guess it should be as long as it's a 5V MCU - the output is fairly clean, as long as the decoupling capacitors (typically 100 nF or so near the MCU) are placed properly, etc...
is there any safest option you can recommend?
Not sure. The PM01 seems like a decent choice. But if you are willing to pay several times the price, look at MeanWell modules.
Do you have other similar small modules to suggest?
Hi, sorry for the late reply. Here are some options, but I don't have personal experience with those modules:
- Hi-Link's more powerful 5W modules, like 5M05
- Some offerings from Tenstar Robot, but they seem worse than the Hi-Links
- Or, if you want more quality, look at Meanwell's offering, they have more expensive modules - with much better quality.
Hi, great job, do you know if the power supply it´s a buck or flyback converter?
Hi! Thanks! It is almost certainly an (isolated) flyback converter, a regular buck converter wouldn't have any isolation between mains and output.
I have the same osciloscope 😊
Very Good !! Thanks
Have you used those modules for a long time?, are they reliable?
Hi, not yet, just did some tests - but they seem to be built decently.
Yes, you can. I'm using it - always on from 2.5 to 3 years now. Stable product as long as the load is less than 400mA.
Thanks!
You're welcome :)
Can it take DC input?
Haven't tested that, but it should be able to. (I don't see why it wouldn't work at around 140-340 V DC, as the AC voltage gets rectified and filtered to provide these DC voltages to the primary-side circuitry, but no guarantee - try at your own risk).
im try 60V DC with HLK 5V.... its still able to work
