Instructions:
The product is a modified wave inverter with a sine wave inverter.(The product also needs a predecessor to work ) It can modify the wave inverter 1000W/2000W/3000W and so on…
to a pure sine wave inverter. First remove the power inverter of the modified wave inverter, and then look at the number of modified
wave transformer transformers. Then look at whether the secondary circuit of the transformer is connected in parallel or in series.
Then, add the transformer parameters, and modify the secondary of the wave transformer in parallel. , Add 16 laps to each secondary
transformer. The secondary of the modified wave transformer is series-connected, and 8 turns are added at the secondary of each
transformer. Then add a small voltage parameter to one of the transformer transformer’s empty feet in the modified wave transformer.
This small voltage parameter uses a single 0.6-copper wire wound inside the transformer: 5 turns.
This small voltage is the link AC: 16V position. (Remarks: Do not open the magnetic ring with the transformer plus parameters.)
After adding the transformer parameters, be sure to replace the high-voltage capacitor of the modified wave inverter with 220 UF/450V.
&Remember: There is a feedback on the high voltage capacitor of the modified wave inverter. Resistance, this resistance is a few hundred K,
but also to change the resistance of large points, not the voltage will not rise. Re-energize test high-voltage capacitor (positive/negative)
voltage is DC380V, after the test voltage is normal, use the link line to provide to the sine wave rear board,
after the rear board output voltage: AC220V/50HZ, output waveform: pure sine wave
