| − | ==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.
