Features: The SASK8654 Inverter Driver Board delivers stable 220V output with selectable square/ sine , featuring essential 220V electric response for safe operate and supporting up to 500W power conversion with built in reverse polarity and under electric defense . This step up electric converter operates at 10V 15V input with 50Hz adjustable frequency, offer electric stabilization for 8V 10V converter , and includes waveform correction capability through external capacitors for optimized efficiency in specific applications. Ideal for electronics engineers and enthusiasts working on communication equipment, solar power systems, or inverter projects requiring stable power conversion below 800W converter capacity. Perfect for off power setups, emergencies backup solution, and electronic testing environments where stable 220V output with configurable waveforms and soft starts functionality is critical. Engineered with accuracy tuned factory presets (50Hz frequency/220V output) and thermal safe PCB construction, this power supply module supports waveform customization while maintaining low 40mA idle current consumption without connection converter .
