The pre-driver board is mainly composed by three parts: the power supply section, PWM driving portion and over-voltage protection section Ģ. This inverter is composed of three parts: pre-driver board, stage driver board and power board.ġ. Overall, this is a uni-polar 12V isolating pure sine wave inverter. Under-voltage protection 10V immediate shutdown over-voltage protection 15V immediate shutdown overheat protection: 65℃. Overload protection 500W immediate short circuit protection voltage alarm 10.3V delay 1.5S Overall efficiency: 87% 300 times the power short-circuit, short-circuit power 200 times Output voltage: Output single phase 220VAC (RMS), a frequency of 50☑Hz.
Nominal power: 300W continuous power: 250W Peak power: 600W 12v 300w uni-polar isolation of pure sine wave inverter Basic parameters
