Byggesæt: Højtaler-beskyttelse for K3503

Højtaler-beskyttelse for K3503Prevent 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 supplyswitch-on delay of the speakers: ± 2 secondsimmediate switch-off of the speakers when switching off the boostervoltage monitor: switch off at +/- 10Vonly suitable for VELLEMAN K3503 2 X 100W car boosterPCB dimensions: 57 x 51mm (2.2" x 2.0") Extra Info - HintsWhen protection works to early due to voltage drop of the battery, please change ZD1 and ZD2 by 9.1 or 8.2V type.When the power supply is not stable, change C5 and C6 by 47µF.
