12v 10A Stereo Speaker Protection Board PCB only

12 V 10 A Stereo Speaker Protection PCB Board (Bare PCB)This PCB is designed for building a stereo speaker protection circuit with delay and DC fault detection. Performance depends on components used and assembly quality.Working Voltage:Input supply: 0 to 12 V ACOnboard rectifier and regulator support operation with input up to 30 V ACCurrent Capacity:Relay switching current: up to 10 A (using standard “sugar cube” relay, depends on relay used)Protection Features:Turn-on delay: approximately 1 to 2 seconds to prevent speaker damage from power-on/off transientsDC detection: relay remains OFF if DC voltage above approximately 2 V is present at speaker outputFault condition detection prevents relay activation to protect speakersChannel Support:Dual-channel protection for stereo amplifier outputsIndicators:LED indicators for:Power/OK statusFault conditionConstruction:Bare PCB (components not included)Designed for through-hole componentsComponents are commonly availableConfiguration:Requires appropriate relay, components, and assemblyDesigned to be connected between amplifier output and speaker loadFinal performance depends on component selection and build qualityIntended Use:Speaker protection in stereo audio amplifier systemsPrevention of speaker damage due to DC offset and switching transientsSuitable for home audio systems and DIY audio projects
