if using voltage converter to change 220V to 110 ( use US apps in India), do I need to worry about 60 to 50Hz?

Question

Can I use multiple outlets to a connect mutiple appliances after converting 220 to 110V?

Does converters for continuous use heat up fast or can they be "really" used continuously?

Answer 1

no. common household appliances will work with 50 or 60 hz, and most consumer electronics change the AC to DC anyway. it doesnt matter

Answer 2

The converter itself and most appliances will work equally well on 50 or 60Hz; there's just not that much difference, and most appliances are designed to work on both. The exception is clocks, which use the line frequency for timing. Continuous rating should mean continuous use for an indefinite period. Anything else is mislabeling. In using multiple outlets, make sure you do not exceed the maximum current rating of the converter when all connections are active. Do not add the power of each appliance, add the current drawn and make sure the total does not exceed the converter's rating.

Answer 3

Yes, you do have to worry about the frequency. Some appliances, mostly motor driven ones and ones that include inductors in one form or another are affected by this. Purely resistive loads such as lamps are not affected by it. Computer power supplies are often rated for 47Hz to much higher than 60Hz, so it is usually safe. Fluorescent light fixtures are NOT safe as the ballasts are designed for specific frequency in mind.

Yes, you can use multiple outlets assuming the total does not exceed the capacity.

If the equipment is rated for continuous duty, then at the rated power, it should not heat up to the point that is unsafe.

That said, the meaning of "continuous" is not often what you think of continuous. It can easily mean, 100% rate for 5 minutes or something similar. Read carefully what it means....

Personally, for continuous duty use, I use the safety factor of 2 method. That means I use at 50% of rated capacity.

Answer 4

tkquestion is right.for some reasons you must consider some precautions for continued safety.try to look and add all the wattages you are using for a certain outlet. the sum must not exceed half of the total wattage of the converter for continued safety even for continuous use.(",)
