(i meant to post this in general chat sorry)
hello, a new and inexperienced electrician here : )
i have a 17 volt ac>dc power supply and it can offer 1.1 amp
i hope to power a little relay which needs only approx 5v and 40 milli amps to trigger it. So when I use a variable resistor on the psu to drop the volts down to 5v, the amps drop too and so much so I cant power my relay with it. : /
i know the relay works at 5 v as i have another psu to test it with
maybe i need change the regulator inside this 17v psu?
thanks for any help. : )
