Introduction
and
Features
Thank
you
for
selecting
the
Extech
DCP42
Switching
Mode
Power
Supply.
This
newly
re
‐
designed
laboratory
grade
power
supply
differs
from
a
conventional
power
supply
in
that
it
can
calculate
and
change
the
voltage
and
current
limit
points
according
to
the
available
maximum
power.
Therefore
the
maximum
limits
of
the
voltage
and
current
are
changeable
according
to
the
rated
power.
A
conventional
power
supply
has
only
a
set
maximum
voltage
and
current
such
that
all
of
the
operating
V
&
A
must
fall
within
these
limits.
The
DCP42
offers
cost
saving
and
space
saving
advantages
as
one
constant
‐
power
power
supply
can
do
the
work
of
several
conventional
power
supplies.
The
DCP42
is
highly
efficient,
incorporates
upgraded
SMPS
circuitry
with
small
form
factor,
benefits
from
an
automatic
cross
‐
over
for
CC
and
CV,
has
three
(3)
Voltage/Current
presets,
and
can
be
remote
controlled.
The
DCP42
is
perfect
for
solving
a
variety
of
loading
conditions
and
applications.
Features
include
the
following:
Dual
action
(Course/Fine)
tuning
provides
smooth,
accurate,
and
quick
setting
of
Voltage/Current
Setting,
changing,
and
verifying
the
current
limit
level
is
convenient
and
can
be
performed
without
output
pole
spiking
The
Remote
Control
feature
permits
output
ON/OFF
and
Voltage/Current
adjustments
without
the
need
to
touch
the
front
panel
of
the
power
supply
The
USB
port
offers
PC
connectivity
for
programming
and
running
ramp/soak
cycles
with
20
programmable
sets
of
Voltage/Current
and
varying
test
durations
(up
to
999
cycles)
The
DC
ramp
and
waveform
generator
can
either
be
panel
set
or
set
by
the
supplied
software
which
previews
the
final
waveform.
Applications
and
industries
where
the
DCP42
can
be
employed
include
laboratory,
telecommunications,
production
testing,
field
testing,
DC
network
powering,
and
more
Three
(3)
user
programmable
Voltage/Current
settings
offer
quick
recall
of
frequently
used
test
settings.
This
device
is
shipped
fully
tested
and
calibrated
and,
with
proper
use,
will
provide
years
of
reliable
service.
