3000W Pure Sine Wave Inverter Power Board Post Sine Wav Amplifier +heat sink Description Function: Pure sine wave inverter completes the board Technical Parameters: Product Name: Modified wave inverter to pure sine wave post-grade board Input voltage: DC380V. Input voltage: AC16V. Output voltage: AC220V. Output frequency: 50/60HZ "adjustable". Output waveform: pure sine wave. Board specifications: 200X85X50MM. Operation instructions: The product is a modified wave inverter to correct the sine wave inverter, and the modified wave inverter 1000W/2000W/3000W and so on... can be modified into a sine wave inverter. First remove the modified wave inverter rear stage power tube, then look at the modified wave transformer transformer, and then see if the transformer secondary circuit is connected in parallel or in series, then add the transformer parameters, and the modified wave transformer secondary is parallel. , add 16 turns in the secondary of each transformer. The modified wave transformer secondary is in series with 8 turns in each transformer secondary. Then in the modified wave transformer, one of the transformers has a small voltage parameter added to it. This small voltage parameter uses a single 0.6 copper wire and is wound inside the transformer: 5 turns. This small voltage is the link AC: 16V position. (Remark: Transformer plus parameters do not open the magnetic ring.) After the transformer parameters are added, be sure to change the high-voltage capacitor of the modified wave inverter back to 220UF/450V. "Remember: There is a feedback on the positive side of the high-voltage capacitor of the modified wave inverter. Resistance, this resistance is a few hundred K, also need to change the resistance value of the large point, not the voltage will not rise. 》Re-power test high-voltage capacitor (positive / negative) voltage is DC380V, after the test voltage is normal, use the link line to provide the sine wave rear stage board, after the output voltage of the rear stage board: AC220V/50HZ, output waveform: pure sine wave.
