According to the "IDC China Projector Market Tracking Report Q4 2020" , around 3 million home projectors were sold in China in 2020, representing an annual growth of 7.5% .

IDC predicts that the compound annual growth rate (CAGR) of the Chinese projector market will continue to exceed 15% until 2025.

The Chinese brands XGIMI, JMGO, Xiaomi Group, Dangbei, and Hisense occupied the top five positions in the market. This allowed them to break the more than ten-year dominance of foreign brands in the Chinese projector market and develop numerous new technologies in the field of intelligent projection.

Recently, Tonghui Electronics developed a custom-designed TH300 automatic power supply testing system for a leading Chinese projector manufacturer.

This power supply test system enables 4-channel simultaneous testing and can test 12 different parameter groups (including numerous individual tests), including:

• Starting behavior without load at low voltage
• Ripple measurement at low voltage and full load
• Protective functions
• Efficiency
• Dynamic load tests

The system automatically generates customized data analysis reports .

The components used in the system, such as power supplies, electronic loads, and other measuring instruments, were entirely developed and manufactured by Tonghui. Based on more than 20 years of technical experience and manufacturing expertise, Tonghui offers reliable testing solutions with high quality and an efficient user experience.
