ADC501H

500W 100-240Vac or 24/48Vdc powered 70-100V transformerless direct output amplifier

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 and redundancy. All protections, over current and over temperature are included, insuring a high reliability.

Battery charging possible with the CHG40 add-on board  available separately.

An optional test evaluation board is available to order separately.
