1. Pure sine wave output 2. Low work noise, high efficiency inverter. 3. Small, light and artistic, benefited from adopting the SMD paster technology. 4. Featured with high reliability and low failure rate by using the advanced Double-CPU single chip intellectual control technology. 5. Cooling fan is intellectual controlled, and its working status is controlled by CPU, which mostly increased its service life and helps to save the power consumption, improve work efficiency and lower the working noise. 6. With complete protections
