NCAS500MP Insulation sheet

The NCAS500MP integrates two NCORE® Class D amplifier channels intended for two way active loudspeaker designs. The module combines one full bridge high power channel and one half bridge medium power channel on a single PCB assembly. The full bridge channel delivers up to 400 W and is intended for low frequency drivers. The half bridge channel delivers up to 100 W and is suitable for midrange or high frequency drivers. This channel allocation supports efficient distribution of output power within compact active speaker systems. The module includes an integrated switch mode power supply based on a regulated half bridge topology with synchronous rectification on the main output rails. An automatic input voltage doubler supports operation across a wide range of mains input voltages. A dedicated low power standby switch mode power supply is included and complies with 2013 ERP Lot 6 requirements for a maximum standby consumption of 0.5 W. The NCAS500MP is intended for use in active loudspeakers such as studio monitors and compact PA systems where integrated amplification and defined channel allocation are required.
