Velleman - K3506 - Anti højttaler blob til auto-forstærkere

Prevent any annoying plop occurring in speakers when switching the car booster on og off. In addition, it provides protection for the MOSFET transistors og the car batteri (monitoring the spænding drop). The entire circuit can be built into the car booster housing.

Tekniske detaljer:

• Soft start of the switched mode strømforsyning
• Switch-on delay of the speakers: ± 2 sek.
• Immediate switch-off of the speakers when switching off the booster
• Spænding monitor: switch off ved +/- 10V
• PCB dimensions: 57 x 51mm (2,2" x 2.0")

Tips:

• • When protection works til early due til spænding drop of the battery, please change ZD1 og ZD2 by 9.1 eller 8,2V type.
  • When the strømforsyningis not stable, change C5 og C6 by 47µF.
