does anyone have an electronic circuit to switch 24 volt DC to 12 volt DC and handle 2 amps.?

Question

Its for a trailer hitch and I Need to build three at a reasonable price

Answer 1

I would buy something premade with your specs, unless you want to turn it into a design-it-yourself project.

By the way, voltage division wastes a *lot* of energy, as you are constantly drawing current to create a voltage. The voltage is also increasingly inaccurate the more current you draw away from the divider.

A better way to do it would be to use a high-frequency 50% duty-cycle square wave oscillator, and some high-power transistors. Effectively the average DC voltage would be 12V. To help hold the voltage steady, use a cap of a reasonably large value (depends on the freq of your osciallator). To control the overshoot, use a smaller cap (about 100 times smaller than your others). The efficiency of this circuit is amazing...

Answer 2

the respond is around 540 watts at one hundred fifteen Volts. 50 amps at 12 volts converts to 5.2 amps at one hundred fifteen volts. (think of 12 x 50 = one hundred fifteen x 5.2, capability in = capability out) yet there is the inefficiency of the inverter (ninety-ninety 5%). Assuming ninety% as variety of a worst case, then your 12 volt dc amps pass to something like 11.a million amps (extra appropriate performance is accessible with new instruments). As stated, inverters are actually not ideal while convertering 12V into 115V. If the converter consumes 600W from the 12V battery (50ampsx12volts=600watts), then a ninety% effecient converter might generate 540W of 115V AC capability maximum suitable case particularly of 600watts. the different 60W is misplaced generally as warmth. yet continuously you're able to deduct with the aid of a 20% margin of errors for the inductive transformers interior the digital equipments. with the objective to be secure, you will basically have 600watt-30% = 420 watts with no difficulty used. cheers.

Answer 3

You mean store bought, or are you designing your own?

If you want to know the basic principle of voltage division:

----------edit-----

When you design your own circuit, don't make the mistake of only looking at the resistance required; also look at how may watts (power) are being consumed by each resistor. The resistor has to be able to withstand the heat generated by the amount of current flowing through it. At the electronics store, you will notice that there will be resistors of the same size in ohms but rated for different maximum wattages. Ask the guy at the store for advice.

Just buy a voltage regulator off digikey.com for 2 bucks.
