ENCLOSURE
The AE33 enclosure is very robust and made from sheet metal. The enclosure mechanically
protects the delicate inner measurement parts. The dimensions of the enclosure meet the rack
mount standard for the instrumentation.
POWER SUPPLY
The power supply module is composed of the mains inlet, the power supply electronics and
the cooling fan. Since the power supply electronics heats up, it is mechanically integrated in a
separated and thermally sealed area.
MAINS INLET
The mains inlet accepts standard EU, US or UK supply cords. It is composed of the inlet itself,
the EMC filter, the main fuse and the primary ON/OFF switch. The switch is a part of the power
supply module.
COOLING FAN
The cooling fan is also a part of the power supply module. The control electronics measures
the temperature of the power supply area and switches on and off the cooling fan.
MAIN COMPUTER
The main computer processor also generates quite a lot of heat. It is integrated in the power
supply area so it can be cooled down together with the power supply electronics. The highest
level control software and the user interface are implemented on the main, PC based
computer.
ELECTRONIC BOARDS
The system features modular design so the electronics is composed of various electronics
boards which mechanically fit together with other mechanical modules. The low level control
