Der 5 -kW -FM -Sender EM 5000 He Dig Plus wurde vom OMB -Entwicklungszentrum für hocheffiziente Sender erstellt. Es besteht aus dem hohen Effizienz von 5 kW -Verstärker, FMA 5000 HE mit 72% Effizienz und dem EM 25 Dig Plus, einem 25 -W -FM -Sender. Der hohe Effizienz von 5 kW -Verstärker hat einen ungefähren Verbrauch von 6600 VA bei 230 VAC. Daher zahlt es sich in kurzer Zeit aufgrund seines niedrigen Verbrauchs aus. Dieser 5 -kW -FM -Sender ist auch in der Dual -Laufwerk -Version
erhältlich
