400W converter 12v 220v pure sine, transformer 12v 220v

Provides 400W continuous power, with a peak of 800W when starting charging. Converts 12V DC to 220V/230V AC, providing pure sine wave with conversion efficiency above 92% to minimize power loss during conversion and low load loss The output waveform of the power inverter conforms to the AC waveform of the public network and is suitable for inductive and capacitive loads. It extends the life of the equipment and reduces the failure rate. Can be used with electrical equipment such as TVs, home theaters, car stereos and other sensitive loads for a long time. The operating noise is less than 20dB, ensuring a quiet environment Equipped with safety indicator light and digital display for undervoltage and overvoltage protection, overtemperature protection, overload protection and short circuit indication, as well as ground failure circuit switch for enhanced safety measures This 400W inverter withstands harsh environments and better impacts than plastic housings. Advanced intelligent cooling fans automatically activate when the load exceeds 150W or the internal temperature rises above 104°F, effectively preventing overheating during continuous use Rated power 400W, suitable for precision electronics, motors, new energy and emergency systems
