Revision: 2.1 4-15
4.1.11 Toroidal transformer
The toroidal transformer supplies 24 V for the valves and the circuit board
for motor control on the radial fan. It is fused as follows in the E-Box:
− Primary fuse 800 mA
− Secondary fuse 5 A
4.1.12 Power supply
The power supply receives the supply voltage of 230 V from the ACT1
circuit board.
It supplies the following output voltages:
− 12 V for the E-Box cooler fan
− 12 V for the LM1085 fixed voltage controller
− 12 V via terminal strip 27 for:
− Pressure transducer on sterilisation chamber
− Pressure transducer on steam generator, when necessary
− 5 V to power the digital circuit board DS1002
− 5 V for the printer (optional)
The output voltage on V1 must not fall below 5 V!
This voltage is factory set to approx. 5.2 V.
