2.Rectifier with original HY 25A 1000V rectifier bridge.
3.The input voltage of the power amplifier is less than AC35-0-AC35V.
4.Two fully shielded sealed relays 10A are used.
5.With boot delay, output DC protection cut off, power amplifier power supply overcurrent protection, status indicator LED.
6.The delay state when the power is turned on, the LED flashes. After detecting that the power amplifier has no DC normal, the relay is turned on. The LED stops flashing.Keep the light up.
7.When the power amplifier outputs DC, after the relay is protected, the LED flashes to remind you.
