About this item

  • Widely Uses: 12 V 3 A 36 W ac-dc power supply housed in a compact metal case. This rugged unit is ideal for industrial automation, 3d Print, diy project works, led display, led strip light, etc
  • Safety Performance: Built in fuse providing a voltage regulated single output which can be adjusted with an on board potentiometer. With short circuit, overload, over voltage, protection function to protect your device
  • High Efficient: A highly efficient and reliable dual output enclosed power supply, with a high operating temperature of -20~+60°C and cooling by free air convection
  • Energy Saving: Uses a switching regulator to convert ac mains power to low voltage dc and it does this much more efficient than a linear power supply. Switching power supplies also tend to be smaller in size than linear power supplies
  • Power Supply: This switching power supply operates from ac 110 V - 220 V and converts to dc 12 V. Linear power supplies have efficiencies in the 40%-60% range, while switching power supplies fall in the 70%-90% range
  • Notes: Indoor use only. For long service life, please do not let the unit work long hours over rated current

I installed this to supplement my solar panels for running a 12 volt refrigerator freezer combo - took just minutes to install some AC power cables and the DC leads - and now have a backup frig in the garage that I can switch between solar and AC.Construction looks solid and sturdy.Great purchase.

It is powering a linear actuator that opens my window. I have had this for a few months and no problem

Great little power supply. Only problem is it comes from China and takes 6-weeks or more. USA distributors stock all the other sizes, why not this one? For sure, you can't beat the price but I would have paid more to get it quicker.

Poor components used, PSU died on only 1.5-2amp continuous when it's rated for 21amp max. The failure may have been due to the cheap main capacitors. One cap was a dead short while the other was only coming in at half the rating on the label. This failure took out both transistors. Luckily the fuse blew saving other components making the repair fairly easy. I would recommend others to go with a Mean Well brand if looking for reliability. I replaced the failed PSU with a Mean Well with a max rating of 12.5amp that I had on hand while I waited for replacement parts and has been running for 2 months so far. Guess I use the repaired PSU to use in something that doesn't require reliability.

Lack of documentation for the single channel led me to guess which pins were which. Sadly, I was unlucky this time and made a nice big lightning bolt and now have a stinky paperweight. I’m sure it’s a good product, just no documentation that was accessible to me.Edit from the last review: A representative from the company contacted me and offered a replacement. Luckily this replacement and the second one I bought had the sticker on it that had the pinouts unlike the first one. Other than that, groud product and great voltage control.

Smaller than I expected. Its slightly larger than a deck of cards. I am using this for bench testing 12 volt items. Currently I am powering the 12v side of a control board on an RV refrigerator in my garage and its working perfectly. The ability to slightly adjust the output voltage is nice. I'm able to instantly read it with a meter. I have had it plugged in for about 3 days now, No issues at all. I would recommend it.
