4.2.4.3 Transformer 2
The main reason for the transformer T2 is to power the Z- and Dp servos, protected by F6
4
The power supply unit provides the following supply voltages: 4
Secundary Transformer T2
– 40 VDC for the servo amplifiers the z and dp axes.
– 34 VDC for PCB handling system.
– 40 VDC for the component tables (30 V for feeder operation).
– 10 VDC for the component tables (5 V for logic).
– 28 VDC for the monitor.
– 24 VDC for the Y-axis motor cooling device.

4.2.4.4 Voltages in the Power Supply Unit after switching on
When the main switch is switched on, the following voltages are generated and may or may not
be switched (enabled, not enabled) through to the modules:
4
Voltages for the service socket 4
NOTE: The service socket can only be used if the placement system is connected to the main
power supply with a 5-conductor cable (L1, L2, L3, N, PE). 4

4.2.4.5 DC/DC Converter in Main Power Supply
Two DC/DC converter U20 and U30 generate the 24 VDC and 5 VDC, which are used overall in
the electrical system, are located in the main power supply module.
DC/DC converter U20:
1.+24 VDC converted from 52 VDC is split into 4 path
– path 1: power for servo enable
– path 2: SSK relay K6
– path 3: for inrush current limiter servo
– path 4: mainly used: general use of 24V all over the machine
2.+24 VDC converted from 52 VDC is split into 2 path only on the HF3 machine:
– ventilator for the axis unit
– PCB transport control board
DC/DC converter U30:
5 VDC logic power, which his mainly used in the overall machine
