SPEAKER PROTECTION BOARDS

12v / 24v High Current Speaker Protection board using L90 / H90 T Relay for Audio Power amplifiers - PCB Only

High Current - 30 ampere Max output current using L90 / H90 T- Relay

Compact Size - PCB Dimensions - 75 mm x 55 mm only

Working Voltage - 0 - 12 Volt  or 24 Volt AC Supply Required ( use the Same Voltage Relay as the Supply Voltage)

For Example if using 12v supply use 12v relay or using 24v supply use 24v relay

LED Indicators - Red and Green LED indicators for easy fault detection.

Turn on Delay - Delay of 1 - 2 Seconds so the speakers can be protected from harmful on / off Transients.

DC Detection - as low as 2 volt DC can trigger the relay and protect the speakers.
