The Switch Mode Power Supply is located behind the Power Distribution PCB.
To gain access to the Switch Mode Power Supply the complete electronics module must be removed from the lower chassis.
Note: There are no user serviceable components in this unit so access will only be necessary in the event of total failure.
The instrument must be completed isolated from the mains supply before attempting to remove the Switch mode power supply.
It is powered from the mains supply via the Power Distribution Card and provides power supplies to the Power Distribution Card as follows: 5V power, three outputs of 24V power (for the turbomolecular pump, ASU and Opto 22), 28V power for the magnet and 14V power for the capillary heater.
