ANTI SPEAKER PLOP FOR K3503 CAR BOOSTER

Prevent any annoying plop occurring in speakers when switching the K3503 car booster on and off. In addition, it provides protection for the MOSFET transistors and the car battery (monitoring the voltage drop). The entire circuit can be built into the car booster housing. Specifications Soft start of the switched mode power supply Switch-on delay of the speakers: ± 2 seconds Immediate switch-off of the speakers when switching off the booster Voltage monitor: switch off at +/- 10V Only suitable for VELLEMAN K3503 PCB dimensions: 57 x 51mm / 2.2 x 2″
