For those who need good audio protection this is the right choice.
Kit is built with high quality components such as Omron Relay and Uni ohm resistors, wima capacitors etc.
This kit do NOT include transformer. For transformer can be used any standard pcb transformer from 3VA to 4.5VA 2x12V
– When the Red LED is turned on, time measurement or continuous current protection is activated
– When the green LED is on … the speakers are out of danger
Installation must be supplied with voltage +/- 12V … install 2 in parallel relays if required (very high power), the pcb is is designed for 2 relays ..
