Anwendbare Last: Geeignet für induktive Wechselstrom- oder Gleichstromlast von 5 bis 400 V (Last unter 1000 W) zum Schutz von Relaiskontakten oder Thyristoren
Prävention: Es gibt einen Varistor, der verhindert, dass die Spannung zu stark schwankt und der Strom zu groß ist, wodurch das Relais die Punkthaftung berührt
Funktion: RC-Absorptionsschaltungsmodul zum Schutz des Relais oder des Thyristors, da es Schäden vermeiden kann, die durch die induktive elektromotorische Kraft entstehen, die durch die induktive Last beim Ein- oder Ausschalten erzeugt wird. Verhinderung elektromagnetischer Störungen und Erhöhung der Entstörungsfähigkeit des Mikrocontrollers.
RC-Absorptionskreis: Absorbiert die induzierte elektromotorische Kraft der induktiven Last
Formdesign: Verwenden Sie Crimpanschlüsse, um die Verkabelung bequemer und fester zu gestalten
