Rated 5 out of 5 by from Good Unregulated SupplyI have been so accustomed to buying switching supplies that I didn't even think twice before I bought this supply.Turns out it is a good old unregulated supply (Yep AC in --> Transformer --> Full Wave Bridge [4 Diodes in this case] --> 2200uF 25V Filter Capacitor and thats it). {See Schematic and Photos}If you have a sensitive circuit load, a design with little or varied current draw, are worried about noise, or doing anything other than lighting a bulb; I suggest getting a 12V or variable linear regulator (7812, LM317) and appropriate passives and heatsink to add on from the DC supply.Please be aware of what you are getting and design appropriately.NOTE about unregulated supplies: The Output rating on this device is 12v 1.2A, but if you were to hook up a multimeter to it unloaded, the meter would read much more than 12 volts. The multimeter is designed with a very high impedance and draws very little current to make the voltage reading (Thats a good thing). An unregulated supply is current dependant. So as you pull more current (closer to the rating of 1.2A) you would see a drop to about 12volts. This is where the rating comes from.

Rated 4 out of 5 by from Output not 12VI didn't need the connector that came on the adapter, so I cut it off. I then used a meter to determine which wire was positive. Much to my surprise, the output of this was almost 18V, not 12V! Luckily, the device I'm powering with it has an V-in range of 9-28VDC, so it's not a problem for me, but might destroy more sensitive circuits.Still, for the price, it's a great buy.

Rated 4 out of 5 by from Tip is 2.1 mmJust want P.E. and customers to be aware that the tip is actually 2.1 mm and not 2.5 as listed. The 2.5 mm DC jacks I bought do not fit.

I have a westell modem that I need a new ac power adapter for...this is what it says on the plug input 120v AC 60HZ 21W output 12V DC 1000ma - can I use this adapter? if not this one, can you point me to another. Thanks

Asked by: first
This adapter will work in terms of power output, although there is no standard for plug size. The plug on this adapter is pretty common but I cannot guarantee it will work for your application.

Will this work to charge a 12V rechargeable tire inflator like a Hausfeld Campbell CC2300?

Asked by: A_Lock
This is really a straight power supply and does not limit current like a battery charger would, An actual charger would be a safer option.

OK for small audio amplifier?

Will the unregulated supply be OK for an audio amplifier that requires 12V, 1A or does it need to be regulated?
Asked by: JJJJ
Yes this will work fine for a small amp, anything less than 8 watts per channel should be ok.

Can this be used to charge a 2.5 Ah 12v battery?

Asked by: jstroud
Unfortunately no, you will need a dedicated charging adapter for this purpose.

Will this work?

I have a Seiko INstruments Smart Label Priter, Model 220. Seiko no longer has parts. Printer says 12V DC. Seiko says 3 amps would be good.
Asked by: Georgia Peach
This product is not up to the task, no. The stated 3 amp rating well exceeds the rating of this adapter which is 1200 mA, or 1.2 amps. SKU# 120-056 would be a better choice as it is rated up to 5A. The connector it has is 2.5mm x 5.5mm
