Since, it is a pure sine wave inverter, so it is perfect for audio devices, music instruments, radios, DVD players etc. Built-In Cooling Fan】It has a cooling fan to keep the unit from over heating. adopts infinitely variable speed and temperature control settings, according to the heat generated by the work of the machine depends on the fan speed, truly mute, allowing comfortable work in a quiet environment. The sound of the cooling fan is below 45 decibels. Delivers ultra-clean Pure Sine Wave output that is identical to AC power supplied by your utility ,improves AC equipment performance by our low interference technology (L.I.T), ideal for sensitive loads like Televisions,Audio Systems, Variable Speed Tools, Laser Printers, Laptops, CPAP ,and more.

It’s great to have a high voltage inverter, but the efficiency of the inverter is critical. The greater the efficiency of an inverter, the lower the amount of power that’s wasted throughout the inversion process leading to your caravan battery lasting longer. Comprehensive Protection]: At BESTEK, we attach great importance to the safety of our products. This 2000W pure sine wave inverter has seven main protection measures: over voltage, under voltage, short circuit, overload, over current, temperature and voltage isolation protection to ensure the safe operation of the product. If you plug in too many items that have a high wattage, then this can overload your DC to AC inverter which can then develop damage. This is the reason that the higher the wattage threshold, the higher the cost of the unit.
