BOSCH PVA 2P500 PAVIRO Power Amplifier Sprecs:
The PVA 2P500 benefits from the lowest power consumption of any system in its class, minimizing running costs and requiring fewer backup batteries too. The system is extremely flexible and allows architecture changes at any time during installation and has a wide range of announcement/music combinations.
Ideal for small to medium-sized offices, regional airports, mid-sized hotels, factories, schools, and department stores. It can be operated from both the mains and a DC supply. The output voltage is galvanically insulated and is constantly monitored for a 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 IRISNet.
