30A High-power Stereo Audio Amplifier Speaker Protection Board
With Power Integrated AC 100V-220V GND Independent
Description:
The protection board uses a 1.6mm thick 2OZ copper surface, double-sided tinning process, and the input voltage is AC 100V-220V .
Turn on the power supply and the red light flickers to detect the current. The indicator light is always on and the relay works normally. The red light flickers until it is closed for about 5 seconds. If there is an impact, the closing time will be automatically adjusted (the relay will not be closed until the current passes)!
Each positive and negative line of the two channels is independent, suitable for the use of power amplifiers with different ground wires and BTL circuits!
The output and input terminals are 7.62mm spacing, 1/2W metal film resistance, ultra-low internal resistance designed for large current!
The high-power 30A relay, as the core component, is not afraid of contact spark and oxidation, and has no damage to the sound transmission!
