    12v Light Wires
AI Thread Summary
Hardwiring 12V LED lights to 110V house wiring requires a transformer to convert the voltage. If the lights need a DC supply, a 110VAC to 12VDC transformer is necessary. It's important to ensure the transformer can handle the current required by the LED lights. Hardwiring can void home fire insurance if not done by a licensed electrician, so using a plug-in transformer is recommended for safety. Proper equipment and caution are essential when modifying electrical systems.

I have a strand of 12v led lights that I'd like to use as under mount lights for my kitchen cabinets. Is there a way to hook the lights up to my existing 110v wiring assuming there is a converter necessary?
 
Engineering news on Phys.org
do the LED light units require an AC or DC supply ?
they are available in both versions

if AC, then you would need a 110V to 12V transformer plug pack ( wallwart)
if DC then a 110VAC to 12VDC transformer plug pack ( wallwart)

have you got a link to the type of LED light units you have so we can make a more informed response ?

cheers

It requires a DC12V input. Before, I used a 9V wall plug, but now I'm wanting to hard wire them. So I guess I need the 110VAC to DC12V transformer?

Yep. Just look for the DC 12V output wall transformer that has a high enough output current rating to supply the needed current to your LED string.
 
Perfect. Thank you.
 
I assume you are not a licensed electrician so anything you hard wire into your mains supply will void your home fire insurance. Best to stick with a plug in tranny
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
