4.2.4.2 Transformer 1
The main reason for the transformer T1 is to power the X/Y and star axis, protected by F4. Con-
tactors K2, K3 and K4 illustrate fixed elements of the electrical safety concept. In a fault event, e.g.
open cover, the servos are disconnected from the energy.

The power supply unit provides the following supply voltages: 4
Primary Transformer T1 4
– 250 VDC for the servo amplifiers of the x and y axes.
– 150 VDC servo amplifiers of the star axis.
– 34 VDC for the inrush current limiter servo
– 52 VDC for the DC/DC converters in the main power unit
– 52 VDC for camera illumination and computer unit DC/DC converter
