Features
In addition to the
advanced
constant current, constant
resistance, and constant
volt-
age functions, the PLZ-U Series Electronic Load
Unit offers wide variety
of other
features.
Compact and
light
Compact
and light
weighing only approximately 1 1 kg and 17 kg
for 3 channels and
5 channels,
respectively.
High-speed response
In
constant current mode, a current rise and fall slew rate of 2.4 A/ps (PLZ150U) is
possible
(converts
to a
rise and
fall
time of
10 ias).
Simulations that closely resemble
a real load are
possible by using the PLZ-U as a load for DC power transient
response tests and as
a dummy load
High precision and high resolution
Three ranges are built into the PLZ-U
achieving
both
wide dynamic range and high
resolution. The PLZ-U provides displays with up to 5 digits for voltage,
current,
and
power measurement functions as well as minimum preset
resolutions
of
10
pA
(PLZ70UA) and 20
uA
(PLZ150U).
Variable
slew rate
The current slew rate can be
varied
continuously in constant
current mode and con-
stant resistance mode. This feature allows the suppression of transient
voltage drops
due to the wiring inductance that occurs when a load is
switched and transient volt-
ages of constant voltage
power
supplies, etc.
Multi
channels
Up
to five and three channels can be installed into the PLZ-50F
and PLZ-30F, respec-
tively. Each channel is isolated and can be used indej^ndently or linked
with each
other. Different units (PLZ150Us and PLZTOUAs) can be installed
in the frame.
Low noise
High reliability
and low
noise
have been achieved by the adoption of a heat
sensing
variable
speed fan and the
enhanced cooling structure.
Large capacity
Parallel operation is possible on up to
five adjacent load units of the same type.
Five PLZ70UAS installed in PLZ-50F operating in
parallel produce 375 W.
Five PLZlSOUs installed
in
PLZ-50F operating
in parallel produce
750
W.
0 V type
The PLZ70UA
is
a
0 V input operating voltage unit. This feature is a must
for single
cell tests of fuel
cells. Moreover, the operating voltage of semiconductor
devices
is
decreasing more
and more due to the reduction of the power consumption and min-
iaturization of the semiconductor process. The PLZ70UA can
be used to evaluate
the power supplies for these types of applications.
