Plasma TV and Inverter
Hi everybody. I'm living for the moment in a country were black out
are very common and happen daily. The solution here is an Inverter DC- AC with big batteries (like a UPC). I would like to know if it is safe to try to power my 42 inches plasma TV with a modified sine wave inverter (1000W power). It is the only one I found here.. Thank you in advance for your help. |
You will need something like the ONEAC 3KVA unit that has close to a
very pure sine wave. At anything over 1/2 rated UPS power, the sine wave becomes almost a square wave on anything except the very best UPS units. Most of the higher current draw SMPS supplies use the sine wave to double the voltage through a capacitor, diode, and coil doubler circuit. If you apply something too far off from a sinewave and you could be asking for trouble. You will want to check the amount of distortion and variance from a true sine wave at the load you are going to pull and check with the plasma tv manufacture to make sure it is well within specification. |
