INTRODUCTION
Alinco's
DM-33OMV is
a
high ef6ciency...compacl lightweight high
perfomance
switching mode
power
supply-
It is
a.lso engineered
to minimize the switching noise
specifcally for communication use-
Even whea noise occurs. it may be eliminated
with
tle
Noise-Ofbet function. Also convenient functions like
pre-set
voltage, remote
control
and a highly
visible
back lit meter are stardard
in
this
power
supply.
PRESET
FUNCTION
When this function is activated, a
preset
voltage will be supplied
regardless
of
the cunent
voltage setting. To store the
preset
voltage, tum the
switch
to the
pres€t positbn
and
adjust the
preset
voltage
to
the desired
output
level. When this lunction is selected the vol-
tage
adiustment control
on the front
panel
will be deactivated to
proted
trom
over
vottage.
