1. Voltage range is the maximum: nominal voltage of input is between 15%~30%.
2. Voltage range is the precisest: after use AVR, the error of voltage output is less than 1%~2%.
3. Overload capacity is the strogest: can resist 150% above sudden overload without causing voltage to go down extremely.
4. Reaction time is the fastest: the speed of voltage regulation is lower than 0.1 second.
5. Output efficiency is the best: from zero to full loading, the output efficiency is all above 95%.
6. Modeling-design, easy to maintain.
7. Main AVR use H-grade material: can prolong the life of machine.
8. LED display restoration mode.
9. Safety hiding-style switch shield: can prevent damage from carry, and avoid mistake in operation.
