I just went through the same decision and I opted to wait until Oct.2 shipping at DigiKey. My logic was simple. The Mean Well worked for my first build so I'll stick with it. Superstitious? Yes. Scientific and rational? No.

I'll let Mark talk for himself but it's been my observation that Mark doesn't recommend so much as he gives us options and wants us to learn how to make our own choices. He's taught me quite a bit. I'm not sure if he answered the "tell me what to do questions" he would really be helping us.

Pinnochio, have a look at post #136 in this thread and study the photographs. Maybe you will decide to send a message to that diyAudio member and compare notes.

Also, I recommend you train yourself to always ALWAYS check THIS website. After seeing those results, I checked with the Canadian Mouser website and it agrees; mouser.ca says there are 149 in stock.

Hi Audiobear,

The real difference I saw was line regulation and capacitive load that are different. I mean voltage input is different but way ok for my region. I’ll wait to see what Mark says about it. If those settings won’t impact the circuit them I’m really not worried. I just see that Meanwell offers very good specs for so little money.

All the best!

Oops! Looks like I wrote while you were also posting! LOL

Weird, I checked last night and there was none... They must have received an order today!

Default IRM-02-5 AC/DC module

Just for future reference and as alternative. for AC/DC module I used mouser part number 919-RAC02-05SE/277 (RECOM same specifications, dimensions and pin placement as Mean Well) it is more expensive but for me it was still cheaper then to order from somewhere else and pay additional shiping costs.

+1 for JLCPCB! Prices and service are hard to beat. I typically get boards within 10 days of submitting an order to the northeast US.

Hi,
I tested my PS today. First time the power is ON by flipping the switch, there was a delay with seems to be relay clicking, then I heard the relay click again and measured 120 Vac at P1D and P1N. Measured voltage at LED On-Off at 5.1 Vdc.
When I flip the switch back to OFF position, the voltage across P1D and P1N stays at 85 Vac. LED voltage 0.0 Vdc.
Any hint on how to troubleshoot? Thank you!

Abe

Oops, forgot to add: When switch is open, "LED voltage 0.0Vdc for LED ON, and 5.1Vdc for LED Off".

Don't the philippines use 220V? If that is the case and you put jumper across 230V you should measure between P1D and P2N and get 220V reading.
If you live in US then the reading between P1D and P1N is correct. But there should be almost no current when off, maybee 1V if nothing connected.
