3.6.1. Inrush current limiter
A mains inrush current limiter provides a "soft start" and enables
several D12s to be powered up at the same time without overloading
the mains power supply. The maximum current drawn during the power
up phase is dependent on the mains voltage, however nominal values
are 5 A at 230 V and 10 A at 115 V and 100 V.
3.7. Fan
A level and temperature controlled fan is incorporated for cooling the
internal components, which allows greater cooling during louder
program material. The fan speed is consequently reduced during quieter
passages preventing background noise interference.
If the D12 heats up a "Temp. Warning" is given out and the fan will
give full cooling power permanently.
For further information please refer to section 6.1. Installation on page
20.
3.8. Remote control
The REMOTE sockets can be used with the dbCAN (CAN-Bus) interface
or d&b Remote Interface Bridge (RIB) to integrate the D12 into a control
and monitoring system.
Note:
A detailed description of remote control via CAN-Bus is given in the
technical information TI 312 (d&b code D5312.E.).
