12v 10A Stereo Speaker Protection Board

12 V 10 A Stereo Speaker Protection Board (Assembled)This assembled board is designed to protect speakers by controlling the output connection based on delay timing and DC fault detection.Working Voltage:Input supply: 0 to 12 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 2 to 5 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 prevents relay activation to protect speakersChannel Support:Dual-channel protection for stereo amplifier outputsCan be used with mono amplifier configurationsIndicators:LED indicators for:Power/OK statusFault conditionConstruction:Fully assembled boardUses through-hole componentsConfiguration:Designed to be connected between amplifier output and speaker loadRequires proper wiring and AC supply for operationIntended Use:Speaker protection in stereo or mono audio amplifier systemsPrevention of speaker damage due to DC offset and switching transientsSuitable for home audio systems and DIY audio projects
