Product Details:
Double sided gold-plated PCB with low internal resistance and high sensitivity Adopting Omron relays, with good performance and long service life.
UPC1237 serves as the core component, with functions such as startup delay, DC protection, power-off shock prevention, etc.
Using a fully sealed high current relay as the core component, it is not afraid of contact ignition and oxidation in parallel. The channels are independent, the current is doubled, and the internal resistance is reduced by half, which is beneficial for lossless transmission of timbre.
Using 7812 for voltage stabilization, with a wide power supply range（AC12-24V）.
Simple circuit, easy installation, no debugging required.
Parameters:
Size: 85x46mm
Package list:
1 × UPC1237 speaker protection board
