Bosch PVA-2P500 PAVIRO Series 2 x 500W Class D Power Amplifier

Bosch PVA-2P500 PAVIRO Series 2 x 500W Class D Power Amplifier

The PVA-2P500 class-D amplifier is a 2 x 500 W 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 energysaving 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 IRISNet.

Key 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
• Processor control of all functions
• Monitoring of the processor system via watchdog circuit
• Non-volatile FLASH memory for configuration data
