A pure sine wave inverter is an electrical device that converts direct current (DC) power to alternating current (AC) power. It is often used to convert the power of a battery or solar panel into a form that can be used to run household appliances. This type of inverter produces a clean, smooth waveform that is very similar to the power that comes from the utility grid. Pure sine wave inverters are more reliable, efficient, up to Maximum efficiency 90%, and provide better power quality than modified sine wave inverters.
Pure sine wave inverters are attached with Intelligent speed regulation of fan. The fan speed will be controlled according to the load and the temperature inside the fan. To ensure the security, Pure sine wave inverters are designed with many kinds of protection function, including input under voltage protection, input over voltage protection, overload protection, short circuit protection, over temperature protection.
