Assembled 3000W Pure Sine Wave Inverter Power Board Post Sinewave Amplifier Description: Features: Product Name: Correction pure sine wave inverter stage plate changeInput voltage: DC380V.Input voltage: AC16V.Output voltage: AC220V.Output frequency: 50 / 60HZ "adjustable."Output waveform: pure sine wave.3000W use the power tube: 8PCS 47N60PCB Specifications: 200X85X50MM.Instructions:The product is a modified sine wave inverter modified sine wave inverters, modified sine wave inverter can 1000W / 2000W / 3000W etc......, change pure sine wave inverter. After the first correction wave inverter stage power tube removed do not, then take a look ata few amendments wave transformer transformer, look at the transformer secondary circuit is a parallel or in series, again plustransformer parameters, modified sine wave transformer secondary is parallel In each of the transformer secondary plus 16 laps.Modified sine wave transformer secondary is a tandem type, in each transformer secondary plus eight laps. Then add the correction wavetransformer where a foot of a small voltage transformer empty parameter, this small voltage parameters using a single copper wire 0.6,in which the transformer winding: 5 laps, this small voltage is link AC: 16V position. (Note: Do not open the magnetic transformerplus parameters) transformer parameters After addition, must take modified sine wave inverter voltage capacitors exchange 220UF /450V, "Remember: modified sine wave inverter high voltage capacitor positive terminal has a feedback resistance, the resistance of afew hundred K, but also for large point of resistance, not voltage does not rise. "Re-energized test voltage capacitors (positive /negative) voltage is DC380V, after the test voltage is normal, use the link line to the plate after the sine wave level, after levelpanel output voltage: AC220V / 50HZ, output waveform: pure sine wave.
