Features:
1. Anti-reverse plug protection, without worrying about burning the power amplifier. Overheat protection and horn protection, adopt electronic + physical dual detection protection.
2. Input overvoltage, input undervoltage, internal overheating, internal power supply short circuit and overload, output overload, output short circuit, DC output, etc., all adopt ultra-fast electronic shutdown protection technology.
3. Three dangerous situations, such as input over 260V, short circuit of internal power supply, damaged power amplifier or output with DC voltage, the amplifier will shut down the internal power supply and maintain the lock. It must be manually shut down for 10 seconds and then restarted before resetting. After other protection is triggered, the power amplifier can automatically resume working after the work environment is normal.
