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 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.
• 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.
• Pilot tone and ground fault
monitoring function via PVA‑4CR12 controller or PVA‑4R24 router.
