Aethalometer
Model AE33
ENCLOSURE
The AE33 enclosure is constructed of sheet steel for strength and durability under all conditions
of field operations. The dimensions are for standard 19-inch rack mounting, with 6U chassis
height.
POWER SUPPLY
The power supply module consists of the A.C. mains inlet, the power supply electronics and the
cooling fan. Since this module dissipates some heat, it is constructed in a hermetically separated
and thermally sealed area.
A.C. MAINS POWER INLET
The A.C. mains power inlet accepts standard EU, US or UK supply cords with the IEC-320 female
connector end. It consists 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 part of the power supply module. It is controlled thermostatically by
electronics within the power supply area, and it switches on and off automatically during
normal operation.
MAIN COMPUTER
The main computer board also dissipates some heat. Consequently, it is installed in the power
supply area to take advantage of the ventilation. The high-level software, which controls the
instrument and provides the user interface, runs on this Windows-CE computer. This code is
termed the Software ("SW"). Upgrades to the Software are published on the Users' Group
website www.mageesci.com/group
