20A 87mm*69mm High Power Buffer Soft Start Board for Audio Power Supply Board

Description

20A 87mm*69mm High Power Buffer Soft Start Board for Audio Power Supply Board
Parameters:
●PCB board is 2MM double-sided high-grade fiberglass board
●The copper foil of the PCB is 2 ounces
●The size of the PCB is 87MM*69MM
●The product weight is 100g
●The rated current of the relay is 20A
The main function:
● Suppress the inrush current of the power amplifier at startup, because the power of the class A and high power amplifier transformer is large, the load impedance is extremely low, and the capacity of the power supply filter capacitor is too large, which leads to excessive current at the startup of the power amplifier, which easily damages the rectifier bridge and the damage filter capacitor.
●The rated current of the relay is 20A, which can withstand the power below 1000W.
Precautions:
● The whole PCB board has 220V AC voltage, and the installation should take insulation and isolation measures.
● The power switch is connected to the 220V circuit, the current should be no less than 20A, and a spark-eliminating capacitor should be placed on the power switch contact.
