The Velleman electric piezo buzzers are specifically designed for applications requiring a highly reliable alarm eller signal with a completely solid state og no electromechanical contact (oscillating circuit is built in). They are replacing the conventional electromagnetic buzzers because of their low effekt consumption, the extremely clear og penetrating sound, the absence of electrical noise, their compact design og their limited weight. A variety of models is available for various tone funktions. Egenskaber: Clear penetrating tone High sound pressure level Lavt strømforbrug Compatible with all traditional burglar alarms Operating effekt: 1-13Vdc / 30mA Tekniske detaljer: Tone type: single / pulse Driftsspænding: 3-18Vdc Specificeret spænding: 12Vdc Strømforbrug: 30mA Osc. frekvens: 2.9kHz Sound level: 100dB Stik type: Ledninger: Sort ledning: stel, Rød ledning: konstant tone, Gul ledning: puls tone Husfarve: Hvid Vægt: 22g Også kendt som: Subminiature buzzer, piezo transducer, sound transducer, piezo alarm.
