Want this question answered?
we need vacuum to remove moisture from tank
transformer is a static device hence it needs form factor.
A step-down transformer U really don't need a step up or stepdown transformer You need a source capable to run your LED it can be a swithcing power supply for istance a battery
This is DC, you need to talk to someone who knows what they are doing,unless you get a kit that has everything already to go. Because everything must be matched from the lights, wire, distance, how many, transformer. Lowes has a few ok kits. If you where looking at say seagull or hinkley, lighting, which are not kits and are expensive, the system must be designed, and your looking at 300.00-600.00 just for a transformer. I install custom outdoor landscape lighting. DC is a very safe way to go,, over hard wired lighting for landscaping.
You need a step up transformer unfortunately. Buy an Ugly's book electrical reference book. They're great and there is a transformer chart in there that will list the proper size or Kva that you will need according to your amperage need.
In home electronics, it changes 120volt AC electricity into (usually) 12volt or less DC electricity for use in small electronic items that do not need high voltage to operate.
why need dielectric test for transformer

With a Step Down transformer. But you will probably have a hard time finding a 240 volt unit. 120 volts units are readily available. <<>> It depends on how big of a transformer that you are looking for. There are many control Transformers in the 50 to 500 VA range that have dual primary and dual secondary. The primary side can be connected to 240 volt or 120 volt and the secondary can be connected for either 12 or 24 volts.

it need a continuous 12volt power supply for the memory
A turbo charger does not need electrics to work it is driven by exhaust gasses.
Bilge pumps and bailing sponges, Paddle leashes and floats, Throw rope are the main gears that you need for kayaking.
You need a 12volt dc power supply. Be aware that these get very expensive if you need more than 10 amps.

You can not change AC into DC using a transformer. A transformer changes the voltage levels. To change AC into DC, you would need a rectifier. To change that into smooth DC you need a capaciter and a voltage regulater
You will need a standard AC transformer. You can purchase the transformer at most Home Depot's.
