Description
The VPA power amplifier is specially designed for marine use. The amplifier has to be installed in 19” rack and occupies 3 HU with addition of a 1 HU ventilation grid.
The amplifier is protected against overload and short circuits. A temperature controlled fan ensure high reliability at high output level and low ventilation noise at lower output levels.
The amplifier operates on 115/230 VAC mains with option for automatic switching to 24 VDC battery backup in case of power failure. The amplifier is supervised by a pilot tone to continuously check the signal path, and a fault will be reported by an indicator in front combined with a closing contact for external fault warning.
The amplifier has a built in selectable chime generator activated by a priority switch to give an alert signal in front of a message.
