12v / 24v Speaker Protection board for Audio amplifiers PCB Only

12 V / 24 V Speaker Protection PCB Board (30 A, Bare PCB)This PCB is designed for building a speaker protection circuit that controls speaker connection using a relay based on delay timing and DC fault detection.Working Voltage:Input supply: 0 to 12 V AC or 0 to 24 V AC (select relay voltage to match supply)Example: use 12 V relay with 12 V supply, or 24 V relay with 24 V supplyCurrent Capacity:Maximum switching current: up to 30 A (depends on relay used and load conditions)Supports L90 / H90 type relay (voltage as per configuration)Protection Features:Turn-on delay: approximately 1 to 2 seconds to prevent speaker damage from power-on/off transientsDC detection: relay disconnects speakers when DC voltage of approximately 2 V or higher is detectedLED indicators: red and green LEDs for status and fault indicationBoard Specifications:PCB dimensions: 75 mm × 55 mmCompact layout for amplifier integrationConstruction:Bare PCB (components not included)Designed for through-hole componentsConfiguration:Requires appropriate relay selection (12 V or 24 V) based on supplyDesigned to be connected between amplifier output and speaker loadFinal performance depends on components used and assembly qualityIntended Use:Speaker protection in audio amplifier systemsPrevention of speaker damage due to DC offset and switching transientsSuitable for home audio systems, subwoofer amplifiers, and DIY audio projects
