3000W Pure Sine Wave Inverter Power Board Post Sine Wave Amplifier Board Assembled

Feature:Product Name: Modified sine wave inverter change pure sine wave stage plateThis product is a Modified Wave Inverter to Sine Wave Inverter. It can change the 3000W modified wave inverter to a pure sine wave inverter.Input voltage: DC380V.Input voltage: AC16V.Output voltage: AC220V.Output frequency: 50 / 60HZ (adjustable)Output waveform: pure sine wave.PCB Specifications: 200X85X50MM.3000W power tube use: 8x 47N60 or 8x 40N60Instructions:First remove the modified wave inverter rear stage power tube, then check how many transformer there are, and confirmation if the transformer secondary circuit is connected in parallel or in series. After confirming all of the above, then add the transformer parameters. If the modified wave transformer secondary is parallel, add 16 turns in the secondary of each transformer, if the modified wave transformer secondary is in series, adds 8 turns in each transformer secondary. Then add a small voltage parameter to one of the transformers empty feet in the modified wave transformer. This small voltage parameter uses a single 0.6 copper wire and wraps around the transformer for 5 turns. This small voltage is connected to the AC16V position. (Note: Do not open the magnetic ring when the transformer is adding parameters) After the transformer parameters are added, be sure to change the high-voltage capacitor of the modified wave inverter back to 220UF/450V. Power test high voltage capacitor (positive / negative) voltage is DC380V, after the te
