Are you looking for a power inverter for large-wattage use? Welltron’s 3000W heavy-duty pure sine wave power inverter is your best choice.
Welltron’s 3000W pure sine wave inverter has high efficiency (maximum of more than 90%) and stability. It produces pure sine wave power, which is cleaner, more stable, and safer. It is hard wiring and provides constant and reliable power output for almost all types of electrical appliances, especially sensitive electronics. Our 3000W inverter is suitable for computers, radio equipment, home theaters, and heavy-duty applications. The system has a temperature-controlled cooling fan and generates minimal harmonic distortion.
Input and output are fully isolated. With low/over-voltage protection, over-temperature protection, overload and short-circuit shutdown, and alarm, as well as low battery alarm, you can trust that your appliances are protected from any possible damages.
Welltron’s 3000W pure sine wave inverter is a reliable and safe solution for your power needs. Established in the 1970s, Welltron has been providing the best quality products and services for more than four decades. We are committed to providing power solutions that meet market demand.
