The
BEST
instruments can be now connected to the mains power. The
TetrAMM
and
PreDAC
units use the CAENels PS1112 power supply. The
PS1112 linear power supply can be used either with a 115V – 60Hz AC power line
(e.g. United States) or with a 230 V – 50 Hz AC Line (e.g. Europe); be sure to select
the correct input voltage rating by switching the AC Line Voltage Select switch
placed on one side of the box. Possible switch positions, one for each input voltage
rating, are shown in the following
Figure 14
(230V and 115V respectively):

The
BEST
Central Unit is powered using an internal power supply unit with
extended input voltage range (100 - 240V).
After connection to the main power, the
BEST
units are now ready to be used. To
switch on the units use the power buttons located on the rear side of the
TetrAMM
and
PreDAC
and on the front side of the
BEST
Central Unit.
