PRODUCT DESCRIPTION

Offered here is a TWENTY (20) new good quality   Access Control Power Supply Circuit Board Rated 3Amp for those who likes to build their own power supply.  A typical access control power supply looks like this:   or these: and when closed look like this .  They all look complicated but is actually very simple and you can build it yourself!

Here is how.  A typical access control power supply like the one above cost over $160. 

Here is a blow up photo of how the inside parts look like:

With reference to the photo above, it consist only four parts. 

1. The metal casing (you can get it locally from your hardware store).

2. (Upper left hand corner of photo above) An AC110V to AC12V step down transformer (if you are in the US) ; or AC220V to AC12V step down transformer (if you are in Europe).  This is available also from your local electrical store or radio shack or even Wal-mart.  Please note, it is AC12V, not DC12V.  Because this circuit board is rated 3Amp, the current rating for your step down transformer should exceed 3Amp.  Preferably, it should be rated 3.0Amp or more.  The item that you are buying does not have a built in AC110V-260V step down DC12V transformer, so you need to buy the transformer that we do not sell.  If you cannot find the transformer, then we suggest you buy this alternative model (click this icon ) which comes with a built in transformer.

 

3. (bottom of photo above, resembles a black block) The rechargeable battery (this is optional, and is very useful in the event of a blackout).  This is available also from your local electrical store or radio shack or even Wal-mart.  This battery should be rated at least 5.0AmpH to give you at least 10 hours of power supply in the event of a blackout (this depends on how much power your electric strike consumes, most of them is rated under 0.4AmpH).  For those of you who are not worried about blackout, you don't have to buy the battery which will further lower your cost. 

The rechargeable battery should be rated at least 5.0AmpH or preferably 7.0AmpH like the one shown in the photo above.  The battery should also be rated DC 12V.

4. (Upper right hand corner of photo above) The access control circuit board which you can buy from us now with this listing!

All the above can be bought and cost less than $60 or less, depending on how and where you buy the parts!  The rechargeable battery is optional.

 

KEY FEATURES:

The circuit board supports NO (Normally Opened) or  NC (Normally Closed) rated electric strike / deadbolt. 

It has safety fuse to prevent short circuit.

It also has battery charging feature.  Simply connect the two cable shown above to a rechargeable battery rated at least 5.0AmpH or preferably 7.0AmpH like the one shown in the photo above.  The battery should be rated DC 12V.

Because this board is rated 3Amp, the minimum current rating for your step down transformer should exceed 3Amp.  We strongly suggest you get one that is rated 3.0Amp or more. 

The circuit board comes with an adjustable 0-15 seconds door open time delay.  In other words, if you set the delay at 10seconds, the door will stay unlocked for 10 seconds.


If you prefer a board that is rated 5Amp and comes with remote controller and built in step down transformer, then click on this icon:
