Function Description
●
The switched mode power packs (multiple AC/DC converters) converts the line voltage to the
individual voltages needed.
●
No conventional power supply transformers are required.
●
Four power packs PS1, PS2, PS3 and PS4 are connected directly to the mains voltage 3 x
400VAC (exception low voltages countries).
The following voltages are generated:
PS1: 300VDC/160VDC
PS2: 42VDC
PS3: 28VDC
PS4: 24VDC
●
The high intermediate circuit voltages of the main axes (300VDC) and head axes (160VDC)
are backed up via the backup battery CAP and backup capacitors to the Fuse and Distribution
board FD assembly and on to the axis control assemblies. (MGCU and MHCU).
●
Voltage of 300VDC from PS1 used to charge capacitor battery in CAP assembly; this backup
battery emits energy to the main axes and also can absorb energy from the main axes.
●
The capacity of power pack PS1 is not enough for main axis acceleration (gantry jump) so
energy is taken from the CAP, during gantry breaking the CAP is recharged, this function of
the backup battery removes the need for a ballast circuit.

8.2 Wiring colour description
There is wire colour code to show voltage level of specific single wires. So you can identify voltage
levels at tested parts using wire colors:

8.3.1 Circuit Diagram of Power Supply TX
The diagram above shows a simple overview of the voltage generation with the SMPS.
●
The power pack PS1 converts the mains input AC voltage into 300VDC (for intermediate
circuit voltage man axes) and 160VDC (for intermediate circuit voltage head axis).
●
The 300VDC is run via the backup battery CAP1 to the CSB (Contactor-based Safety
Breaker) the voltage is charged/discharged in a controlled manner via the pre/discharge board
A2 and the energy is backed up by the backup battery CAP1.
●
The power pack PS2 converts the mains input AC voltage into 42VDC.
●
One link of the 42VDC voltage is run via the CSB from where it is then run back to the FDB
and distributed as 42VDC_S (switched).The other link is directly to the discharge head buffer.
●
The power pack PS3 converts the mains input AC voltage into 28VDC.
●
The power pack PS4 converts the mains input AC voltage into 24VDC.
●
This 24VDC voltage is run via the CSB, from where it is then run back to the FDB and
distributed as 24VDC_S (switched).
●
All voltages are protected by the Fuse & Distribution Board (FDB).
