The television room in the car? The fridge? The hair dryer? My coffee? How can I have it in my car?
Some time ago I thought about installing a UPS in the car, using the 12v present, however had to make a number of adjustments. How not like enjambres, I spent my idea for a friend and he shared me that there is a device made for this, or anything enjambres, with total security and great practicality.
I went searching and found the inverter 12 volts DC to 220 volts AC, 12VDC to 220Vac.
But was the question, does what it promises?
I tested the cigarette lighter with a mobile phone charger, then with a notebook charger, perfect, but when I tested a drill 500 watts it triggered off the protection.
Then I realized that when you have a power failure, in this case the fall is by wire gauge hipodimencionada be small, it "understands" that the battery is lowering excess and off to prevent the motor stay committed.
Then I put the battery clamps that come with the product, interesting that the gauge is higher for the claws, and direct plugged in the battery, wonder, worked perfect without fire protection once. As my inverter is 1000 watts, sought a greater burden for the test and of course, wanted it to be an electric motor to see the action of reactive power, was brill as you can see in the video, played a pneumatic electro drill, 680 watts efficiently and without activating any protection.
About reactive power, it is difficult to explain, but basically the whole load only Resistive is do not use the reactive power, causes no return, but the burden of a common electric motor need and give back, so to help put the Encyclopedia link so you can create a better image. pt.wikipedia.or...
I hope you enjoyed.
