High stability and
accuracy with linear circuitry. Linear circuitry
provides low noise and a fast slew rate, which are
essential for super-capacitor testing. |
|
|
Multiple current
ranges provide wide test ranges and make possible
the testing of leakage current alternately with
high-current cycling tests on the same channel. |
|
|
High power bipolar
linear circuitry provides high accuracy and
stability even across zero current and can apply
reverse charge and bipolar current pulse. |
|
|
Test sequences may be
based upon constant current, voltage, load and
power. Other modes include linear ramp, staircase
and other control profiles generated by simulation
of time-domain regimes or mathematical formula. |
|
|
Multiple channels may
be tested with independent control of each channel. |
|
|
Devices may be tested
continuously under steady-state or pulse conditions
with fast current rise time-from 20ms
to 2ms-depending upon current/voltage range. |
|
|
Pulse feature (option)
covers most pulse applications on supercapacitor.
Besides GSM and CDMA, customer may define pulses
with number of stages between 2 and 10. Each stage
width is from 10 x current rising time to 0.5s (all channels under one micro-controller
must use same pulse profile). |
|
|
ESR, capacitance, power and
energy determinations may be made online during
testing.
|
|
|
EPR measuring and self-discharge
monitoring can be incorporated in a testing
schedule. |
|
|
Fast data acquisition— 60-150ms/point
—depending upon the total number of channels.
|
|
|
Plug-in modules provide easy
maintenance.
|
|
|
Multiple safety protections such
as voltage clamp, voltage/current/time/temperature
limit are integrated into the hardware and
software.
|
|
|
Paralleling allows user to group
channels together to achieves greater testing
current when needed. |
