Step down transformer or converter

Check out the Voltage Converter Guide to figure out how to select correct size voltage converter or transformer. Voltage Transformers vs Converters. Stepping Down: takes higher voltage V from the wall outlet and makes it lower V so that it is safe to power your V only device. Stepping Up: the smaller voltage V is converted to a larger one V to power devices from many foreign countries in North America. More windings of wire on the input side of the electromagnet will reduce output voltage correspondingly.

A volt AC converter with 20 windings of wire on input would by default output volts AC if there were 10 windings of wire on the output end of the converter. Induction coils were the earliest form of voltage transformer to make use of this principle, discovered in by Michael Faraday, with what later came to be known as Faraday's law of induction.

Some modern DC powered devices work around this heat and energy loss, such as personal computers, by using a switched power supply instead of a standard linear DC converter.

I opened up the power strip and found that it contained three varistors, one of which was charred. Measuring the charred varistor with a multimeter showed that it was shorted out. This is what must have happened: When I returned from my trip, I plugged in the surge protector the opposite way from before the trip.

Before the trip, there was no more than volts over any of the hidden varistors in the power strips, but with the plug oriented differently, the voltage rose to volts, causing the varistor to short out. Schematic of connections at time of incident What could have happened It could have been much worse. For one thing, if the varistors in the power strip had been sturdier, the one getting the excess voltage might not have shorted out instantly and blown the fuse, but instead slowly overheated and started a fire.

But what concerns me most is the following scenario: After the initial incident, the blown varistor was completely shorted out. This left the power strip with a short between hot and ground , a very dangerous condition.

If at that point I had plugged the step-down transformer into an ungrounded outlet, the chassis of any grounded volt equipment connected to the power strip would have been live with volts , and I would have stood a good chance of being electrocuted.

Never use a surge protector on the volt side of a to volt step-down transformer if the power plug can be plugged in two different ways. It could kill you.
