Instructions

The product is a modified wave inverter to modify the sine wave inverter, you can modify the wave inverter 1000W / 2000W / 3000W, etc. ..., change the pure sine wave inverter. After the first wave of power inverter repair wave inverter removed do not, and then look at the modified wave transformer transformer has several, look at the transformer secondary circuit is connected in parallel or in series, and then add the transformer parameters, the transformer secondary transformer is parallel , Plus 16 turns per transformer secondary. Correction wave transformer secondary is in series, add 8 laps in each transformer secondary. Then in a modified wave transformer one of the transformer plus an empty foot voltage parameters, the small voltage parameters 0.6 copper single, inside the transformer around: 5 laps, this small voltage is the link AC: 16V position. (Note: transformer plus parameters do not open the magnetic ring) After the transformer parameters are added, be sure to convert the high-voltage capacitors of the rectifier wave inverter back to 220UF / 450V, "Remember: positive feedback surge rectifier high voltage capacitors have a positive feedback Resistance, the resistance of a few hundred K, but also for larger resistance, not the voltage will not rise. The voltage of the high voltage capacitor (positive / negative) is DC380V. After the test voltage is normal, use the connecting wire to provide the sine wave to the rear panel. After the rear panel output voltage: AC220V / 50HZ, the output waveform is pure sine wave.

Note:

This product needs to know DIY purchase, if you do not know how to assemble, please do not buy
