NETZBETRIEB & WÄRMEENTWICKLUNG

NETZBETRIEB & WÄRMEENTWICKLUNG IN DER ENDSTUFE

Mit Hilfe der folgenden Tabellen können die Anforderungen für Stromversorgung und Zuleitungen bestimmt werden.

Die vom Stromnetz aufgenommene Leistung wird in Ausgangsleistung für die Lautsprecher und in Wärme umgewandelt. Die Differenz aus aufgenommener Leistung und abgegebener Leistung nennt man Verlustleistung (Pd). Die durch Verluste entstehende Wärme verbleibt u.U. im Rack und muss durch geeignete Massnahmen abgeleitet werden. Zur Berechnung der Wärmeverhältnisse im Rack/Schrank bzw. zur Dimensionierung eventuell benötigter Abluftmassnahmen kann die nachfolgende Tabelle be- nutzt werden.

Die Spalte Pd zeigt die Verlustleistung bei verschiedenen Betriebszuständen. Die Spalte BTU/hr zeigt die abgegebene Wärmemenge je Stunde.
