This power inverter is designed for 12v DC 800 watt, strive to 1000 watt output with the following features
1.) Reverse power protection applied switching tube to do anti-reverse protection;
2.) Applied LM324 for pre-amp over-current (short circuit) protection and low battery short down;
3.) Power-amp over-current and short circuit protection applied lock protection using current transformer isolated. After protection motion, we need to press the switch again to restart the device;
4.) Including 5 seconds shut down function (to protect personal safety, duration adjustable); Single silicon/mixer, dual adjustment;
5.) Mature circuit, reasonable circuit designing, good consistency, component neatly symmetrical,elegant
appearance.
