Product Principle 4-15
Figure 4-12 Schematic diagram of power unit
Configuration 1 is only set for power supply box (AC) before the 02.00.00(Rev 19070) (EGD019F)
version.
Configuration 1 and configuration 2 are set for power supply box (AC), in which the configuration 2
is the main part in and after 02.00.00(Rev 19070) (EGD019F) version.
Configuration 1: AC-DC module (with fan, 600W @ 12V), AC connection board, isolation
transformer.
Configuration 2: AC-DC board (300W @ 12V), without the AC connection board, no isolation
transformer, fan adapter board, independent fan.
4.5.1 AC-DC Module
AC-DC turns electric supply to direct current power supply.
AC input: the voltage is 200 to 240 Vac; 100 to 127 Vac, 50/60 Hz.
5VSTB output: standby power supply. It outputs to main control system when AC is in the
place.
12 V output: is controlled by main control system, non-standby power supply.
The signal when AC is in the place: reminds the validity of AC input. Main control system
goes into active standby via AC-DC module.
