Transformer (Voltage transformer)

Double wind transformer can either step up or step down the voltage that supplied in it..

Let's say from 240v step to 415v.. Or may be 240v step down to 12v..

And the coil in it are made by copper wire..

We do have :

240v to 12v

240v to 24v

240v to 48v

240v to 110v

240v to 415v

415v to 110v

And their size are calculated by the VA..

As a example, 240v to 12v, you need 1 ampere for 12v, so it will be 12v x 1A = 12VA..

The other way round, 1A for 240v output will be 240v x 1A = 240VA..

But normally, we stock those common size such as 25VA, 50VA, 100VA, 150VA, 200VA, 300VA, 400VA..

Larger one will be need to order from factory..
