Constant Current£¨CC£©
In CC mode, the electronic load will sink a constant
current regardless of the changes of input voltage.
Constant Voltage£¨CV£©
In CV mode, the electronic load will attempt to sink
enough current to control the source voltage to the
programmed value.
Constant Resistance£¨CR£©
In CR mode, the module will sink a current linearly
proportinal to the input voltage in accordance with
the progrmmed resistance.
Constant Resistance£¨CR£©
In CR mode, the module will sink a current linearly
proportinal to the input voltage in accordance with
the progrmmed resistance.
Constant Power£¨CP£©
In CP mode, the electronic load will dissipate
power in accordance with the progammed value.
If input voltage increase, input current will
decrease.
Transient Mode
Transient operation enables themodule to periodically
switch between two load levels, as might be required
for testing power supplies . Transient operation can be
turned on and off from the front panel ( shift + numeric
key”2”) . Before you turn on the operation , you should
set the parameters associated with the transient
operation. The parameters include: A level, B level,
frequency, duty cycle and transient testing modes.
There are three different transient testing modes :
continuous, pulse, and toggle.
Continuous Mode
In continuous mode, the electronic load generates a
repetitive pulse stream that toggles between two load
levels. Load could switch the state between two value
settings, A/B.
In pulse mode, the electronic load generates a
transient pulse of programmable width when pulse
transient operation is in e ffect. Th e load will
automatically switch to A level after maintaining A
width time. Then it will switch to B level. The load will
not switch to A level again until the instrument
receives the pulse signal.
Pulse Mode
In pulse mode, the electronic load generates a
transient pulse of programmable width when pulse
transient operation is in e ffect. Th e load will
automatically switch to A level after maintaining A
width time. Then it will switch to B level. The load will
not switch to A level again until the instrument
receives the pulse signal.
Toggle Mode
In toggle mode, the electronic load will switch
between A level and B level when receiving a
trigger signal after the transient operation is
enabled. The following picture shows the current
waveform in toggle transient operation.
Automatic Test Function
The automatic test function of the IT8500+ series
electronic load is useful for simulating various
tests and allows the user to edit up to 10 groups
of testing files. Each file has 10 steps and up to
100 files can be edited and saved into the
EEPROM.
User can also set the default power-up mode to
be automatic test. It improves the productivity and
automatically judge the product quality.
List Mode
List mode allows you to generate a complex
current sequence. Moreover, the mode change
can be synchronized with an internal or external
singal, to accomplish dynamic and precise test
which can save cost for users.
Users can edit step value, pulse width and slope
sequence and meet a complex test request. A
list file includes following parameters: file name
step counts (range 2-84), time width of single
step (0.00002s-3600s), step value and slope. The
edited list file can be recalled easily. The DC
load provides 7 nonvolatile regisers to save list
files setting for recall later. In the list mode, the
DC start to run the list file once receiving a
trigger signal, continue to run until end of the
operation or receiving another trigger.
Remote Sense
When working in CC, CV, CP and CR mode, if the
electronic load consumes a very large current, it
will cause a voltage drop in the leads between the
connected device and terminals of the electronic
load. In order to ensure testing accuracy, the
electronic load provides a pair of remote sensing
terminals in the rear panel where users can sense
the output terminal voltage of the connected
device. Users should set the electronic load in
REMOTE SENSE mode before using this
function. By eliminating the effect of the voltage
drop in the load leads, remote sensing provides
greater accuracy by allowing the electronic load to
regulate directly at the source\'s output terminals.
Battery Mode
A battery test mode is provided that will measure
the ampere*hour (A *hr) characteristic of a
battery. It measures the time it takes for a battery
voltage to drop to a specified value while drawing
a constant current from the battery.
There are three stop conditions for IT8500+
series loads: Time, capacity and voltage. In
addition, user can make any combination of stop
conditions to achieve “ An d ”, “ Or ”
relationship. When one or more stop conditions
are satisfied, the test is ended and the
discharging time, capacity in ampere*hours
(A*hrs) of the battery is calculated and displayed
on the front panel.
Description: (It supports AC 110V and 220V)
