5 AC Power Supply
The standard components of the transmitter are fully cabled together. The rack therefore
simply needs to be connected to an external AC power supply.
General requirements
The AC power load of the transmitter is determined primarily by the number of amplifiers
and their output power. Furthermore, there is also a relationship between AC power con-
sumption and transmission frequency.
AC supply voltage – three-phase current 230 V/400 V ± 15 %
Power frequency 47 Hz to 63 Hz
DANGER!
Before you connect the transmitter, disconnect the external power supply cable from the
power supply.
WARNING!
Make sure that the AC supply voltage is within the specified range and check all power
cables for possible damage.
