Parameters:
Product Name: Modified sine wave inverter pure sine wave stage plate change
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: 8 / 47N60
Weight: 700g about
Instructions:
Products are modified wave inverter correction sine wave inverter, can be modified wave
inverter 3000W, etc ..., modified pure sine wave inverter.
First, after the correction of the inverter inverter power tube removed, and then look at the
correction of a few transformers transformer, look at the transformer secondary circuit is
connected in parallel or in series, and then add the transformer parameters, modified wave
transformer secondary is parallel , In each transformer secondary plus 16 laps.
The secondary of the modified transformer is a tandem type, plus 8 laps per transformer
secondary. Then in the correction transformer which transformer 1 empty foot plus a small
voltage parameter, the small voltage parameters using 0.6 copper wire, in the transformer
inside around: 5 laps, the small voltage is linked AC: 16V position. (Note: Do not open the
transformer with the parameters of magnetic ring) After the addition of transformer
parameters, we must correct the inverter inverter high voltage capacitors in exchange
for 220UF / 450V, "Remember: correction inverter inverter high-voltage capacitor has a
positive feedback Resistance, the resistance of a few hundred K, but also for large point
resistance, not the voltage will not rise. After testing the voltage of high-voltage capacitor (positive
/ negative) voltage DC380V, the test voltage is normal, the use of cable to the sine wave after
the board, after the board output voltage: AC220V / 50HZ, the output waveform: pure sine wave.
This product is a special commodity and needs to understand related technologies
