ADC501H: 500 W AC or DC powered

GENERAL DESCRIPTION

Thanks to our transformerless direct output solution, the ADC501H digital power amplifier module provides a unique sound, with large frequency response and a better intelligibility for public address systems. The two high efficiency power supplies enable a fast dynamic. All protections, over current and over temperature are included, insuring a high reliability.

The AC/DC powered amplifiers series by NEOsystemes is based on this module and consists of:

ADC501H-00: no option

ADC501H-27: discontinued, see CHG40 Battery Charger

ADC501H-30: providing 30V, 50W isolated auxiliary voltage
