How to Know the Best Step-down Transformer ‘Rating’ for your Equipment

How would you use your imported oven toaster rated at 110V if our voltage supply here in the Philippines is 220V?

The answer is just simple, use a step-down transformer as it converts alternating current (AC) from one voltage to another voltage, like from 220V to 110V.

But some of you may be confuse, because aside from the voltage rating, wattage rating must also be considered. So the real question is how you will know what rating of transformer you will need.

Determining the rating of your equipment is easy. Technical parameters are usually written at the back of your equipment. You should know the voltage requirement. Usually, imported equipment is rated at 110V or 100V. Keep in mind that MERALCO gives out only plus and minus 10% accuracy of the normal 220V. That is why you need a step-down transformer.

For instance, your imported oven toaster is rated at 1500 watts and runs on 110V power supply. If it’s rated in amperes, you’ll just have to do the math of conversion. Usually, the safest allowance of the transformer you can give is 3 times the wattage rating of your equipment. So the safest transformer that can support your oven toaster is a 5000 watts step-down transformer, step-down because MERALCO supplies us 220V and you have to transform it into 110V.

 

Many equipment such as those motor-operated like washing machine and compressors require a large burst of current when during start-up and transition to normal operating circumstances. Some may not be motor-operated but most of them has cooling or heating element such as microwave oven, sterilizers, coffee makers and the likes.

In both cases, you should use much higher wattage of transformer. This allowance is for safety purposes like in-rush currents.

Meiji Electric offers you Step-down transformers with a thorough voltage conversion of 220V down to 110V or 100V. Wattage rating is from 50W up to 10,000W. Anything in between, we’ve got it for you! Meiji Step-down transformers have 110V and 100V outputs in international outlets and come with built-in fuse protection.
