852B VariPulse Throttle

Got a little 852B VariPulse PWM Throttle from Ken Stapleton. Needs 12 VAC, 1.5 amps. Just want to make sure I can use a common AC adapter like this.



See them all the time at the electronics store, but I'm not familiar with the connector (plug). How do I find the female side?

 

Be aware of your polarity.
The label shows

1. that the unit is "negative center", or the hole on the connector is negative and the outside of the plug is +.
2. that the output amps is 1.2 a bit less then the required 1.5
3. that the plug size is 2.1 X 5.5. this is good info for finding the proper jack (socket). You need a size M Coaxial DC Power Jack Radio Shack has a size M Panel-Mount Coaxial DC Power Jack on their web site

Hope this helps,

Gary

 

Radio Shack used to sell one with a variety of jacks so it could be used with just about anything. Don't know if they still sell that particular power supply. You also noted in the post that the VariPulse needs AC. Polarity won't matter.
BTW, that's a female jack in your photo. The male is the one with the pin in the center. I used to make the same mistake until the guy at my local electronics store corrected me. The Radio Shack person probably won't know anyway.

I missed the need for 12 VAC. in the OP.
I should have been in bed at the time I posted.


@ TD

That power supply will not work its output is DC

Instructions if you do not have them.

Thanks. Did some research and there are a lot of different connectors out there, but the 2.1x5.5 mm is pretty common. Found some at a local electronics store.

Now my next quest is to find a 12-18 VAC adapter. (Any suggestions?)

 

You can also use a DC wall wart. Polarity is not important. Just figure 1.4 volts more than you really need. I have some electronics that have the bridge rectifier at the input and can be powered with AC or DC.

The adapter in my original post is for another handheld throttle that needs 12 Volts DC. Ken Stapleton's VariPulse throttle needs 12 Volts AC. Went to DigiKey and found 2239 pages of wall adapters. Guess I will be busy for a while. (I tried a couple of filters but they didn't work; I'll try fewer filters later this evening. If I stay awake.)

 

Well, a trip back to my local electronics store had great results. (Apparently I was looking at the wrong shelf.)



These should work, right?
