Sensidyne Document No. F-PRO-3100 (Rev D)

POWER SOURCES
1.2.1
AC Power
AC power is provided by means of a removable line
cord which plugs into a 3-prong power jack located on
the back of the unit. A 2-prong Euro plug is provided
for 230 VAC operation.
1.2.2
Voltage
The AirCon-2 operating voltage is preset at the factory
for either 115 or 230 volts. This is indicated on the label
located at the rear of the unit. If you need to change
the voltage, do the following:
WARNING
Make certain you unplug the unit before proceeding.
1.
Remove the screws holding the cover
2.
Facing the left side of the unit as viewed from the
front, locate the voltage select switch which is ap-
proximately 1/3 of the way up from the bottom of
the PC board.
3.
To change the voltage, insert a small flat blade
screwdriver into the slot and rotate to the appropri-
ate voltage.
4.
Remove the existing fuse and replace with the ap-
propriate fuse for that voltage.
5.
Replace the cover and provide the proper line cord
adapter for the voltage receptacle.
IMPORTANT
You should place a label or sticker on the unit to show that the
voltage has been changed.
NOTE
Changing factory-set 115 VAC units to 230 VAC
negates CE certification.
1.3.3
DC Power
DC Power is provided by two-hour and four-hour bat-
tery packs. The battery packs can be stacked and inter-
connected to achieve the ampere hour rating required
to meet the most stringent sampling conditions. Battery
packs are recharged with the optional Power Module.
1.2.4
Power Module
The DC version of the AirCon-2 can be run directly off
the power module. If the battery module is also at-
tached, it will slowly charge the battery while still pro-
viding sufficient power to run the sampler. It will rap-
idly charge the battery if the sampler is turned off un-
der the same circumstances. The power module may
also be used as a stand-alone battery charger and may
charge one or more batteries. The unit will automati-
cally reduce the charging currents as the battery be-
comes fully charged. An LED indicator illuminates
when charging and flashes when charging is complete.
If no battery is attached it will flash indicating sufficient
voltage to run the sampler. The power module can op-
erate on 115–230 VAC, 47–63 Hz.
