Read the datasheet, but still not clear. At 12vdc, how much is the smallest current to turn it on/off? Thanks.

The pickup voltage and drop off voltages on relays are different. A 12v relay can pickup at 10v and drop of at as low as 7v. Hence, the current draw will be function of voltage. I hope this helps.

It puts out 12vdc at up to 2 amps. If you only need 500ma, this has more capacity.

I don't know the minimal current necessary, but mine triggers with 12v when hooked-up to my truck battery.

not sure, i use to turn on/off a 9volt battery. Im not technically an electronic master. Sorry man.

It's just a relay so will switch anything you want. It's rated up to 120 V AC but will switch DC of lower voltage. Being a relay the switch is completely independent of the mains which is used to operate it. Hope this helps.

I cant say except that 12 VDC doesn't mater about polarity. 12 VAC is only 8.5 volts effective or / root mean square

Yes - the output voltage is 12 VAC (not 12 VDC as a previous answer stated). But one of the other commenters was correct about the min load. When you just hook up the transformer and test the output without a load, it will read zero, or close to it. I thought the product was broken at first, but one I connected the load, all was well. It's been functioning great since (about 5 months ago).

to start with u cant "see" a "3 volt ac current". its either 3 volts or some measure of current across a load, ie milliamps.voltage is volts, not current.the fact that its "ac" more than likely means its just electrical noise.Assuming its a relay contact for the output u should be able to use it as a switch no problems.if it still didn't work you would tie it to probably ground using a 4.7k or higher resistor, then use a 1k or less to pull the signal up.

It says 19vdc (Volts DC) at 2.1 amps. Thanks for asking, because mine was very warm so I moved the power supply to a place where I could get more air to cool off. ;)

As MSGroves pointed out, each switch is meant to control power flow to each block of 9 connections. It would seem that in the unit you received the switches are not working and power is stuck in the "on" position. As S. Howe pointed out, the low voltage, 12V, is too low to be a safety concern.If you purchased it recently and you are still within the allowed replacement period, you may want to have it replaced for one that functions as it is supposed to but, not for any safety concerns.

It's a good standard power supply that will power pretty much anything that runs on 12 vdc. It's always a good rule to use a power supply that's rated at least double the current load connected to it. In your case you would have plenty of reserve power to run some other things at the same time.

could you please check and tell me what's the rating for the external DC supply ? Vdc ? and current rating (mA)?appreciate your help.thx

Try higher than 12vdc. I use it on a 24vdc system, and have not tested until your message and it works OK.

I don't know but it should be on 5V. I don't think it can run too long at 12 V.

You can just plug it in, the converter will only use what it can, I use this with 9V 3A to convert to 5V, the max current draw I measured is ~ 1.9A.

I also bought this . It only works on a 24 volt dc system. Mine was not advertised to convert from a 12 volt dc source.

so far it doesnt seem to matter/ i ran it on 12 and 24 volts dc>but i have NOT tried IT ON AC?
