The PVA-2P500 class-D amplifier is a 2 ? 500 W professional audio amplifier for evacuation purposes. It can be operated from both the mains and a DC supply. The output voltage is galvanically insulated and is constantly monitored for ground fault. An energy- saving mode and temperature- controlled fans reduce energy consumption and noise levels. The control and monitoring functions are performed via CAN bus. This amplifier is designed for operation in an emergency evacuation system. The amplifiers are usually controlled via a controller and configured using IRIS- Net.
The power amplifier has the following features:
Floating 100 V or 70 V power outputs
High efficient amplifier blocks in class-D technology
Outputs idling and short circuit-protected
Mains operation 120-240 V (50/60 Hz) and/or 24 V DC emergency backup
Electronically balanced inputs
Temperature monitoring function
Pilot tone and ground fault monitoring function via PVA-4CR12 controller or PVA-4R24 router
Processor control of all functions
Monitoring of the processor system via watchdog circuit
Non-volatile FLASH memory for configuration data
Internal monitoring function
Integrated audio relays
Line monitoring function
The power amplifier is processor- controlled and equipped with extensive monitoring functions. Line monitoring for the CAN bus and for audio transmission allows line interruptions and short-circuits to be detected and indicated to the user.
