NGI N6900 120V 300A 3000W Programmable Eload DC Electronic
LoadN6900 Series Distributed High Power DC Electronic
Load Product IntroductionN6900 series is developed based on
NGI's years of experience in testing for power supply,
battery, generator and supercapacitor. It is with high accuracy,
high reliability and high cost performance.According to the
features of high voltage & power DC electronic loads with complex
structures, harsh operating environments, high reliability
requirements, and inconvenient maintenance, NGI has made a number
of optimization based on the international advanced
technology.Application Fields1.Generator2.Charging

LAN/CAN/RS232/GPIB(optional)High reliability designN6900 series has
a comprehensive MOS protection circuit. No matter how much MOS is
damaged, it will not cause short-circuit between the positive and
negative polarity or the positive polarity and the control circuit.
The damage of some MOSs does not accelerate the damage of others,
which can be used continuously.By distributed design, it is easy to
replace or add power modules and is convenient for maintenance and
power expansion.N6900 is designed with power limit circuit and has
fast response, which can prevent the load from being damaged due to
over power.N6900 adopts shielding technology, which has wide
adaptability to harsh test environment, and improves the
anti-interference ability.Short-circuit simulationN6900 series
supports two modes for short circuit: manual and lock.Manual: N6900
will be short-circuited when Short button is pressed. It will stop
short-circuiting when button is released. Manual mode is suitable
for debugging or R&D, avoiding measurement accidents due to
misoperation.Lock: N6900 will keep short-circuiting when Short
button is pressed. It will stop short-circuiting when the button is
pressed again. Lock mode is suitable for long-time short-circuit
test.Auto test functionThe auto test can be used to simulate
waveform. This function can improve the test efficiency and can be
achieved by SEQ function on the menu. Up to 100 sequence files
editing is supported. Each file can support 50 steps.OCP( over
current protection) testDuring OCP test, N6900 will load under CC
mode and check whether the DUT voltage is lower than cut-off
voltage. If lower, N6900 will record the present loading current as
the test result and shut the input to stop the test. If the DUT
voltage is higher than cut-off voltage, N6900 will increase the
loading current until the DUT voltage is lower than cut-off voltage
or it reaches the Max. loading current.Remote sense to improve
measurement accuracyRemote sense is also know as four-wire sense.
When N6900 is working, it will cause a voltage drop in the leads
between the DUT and terminals of N6900, which will affect the
voltage measurement accuracy of the load.When working under CV, CR
and CP modes, to ensure accurate measurement, it is recommended to
use remote sense. During remote sensing, terminals S+ and S- are
directly connected to the output of the DUT, eliminating the
voltage drop in the leads.Charge& discharge testUsers can set
different conditions on the front panel to meet their
test demands. For example, when battery voltage is lower than
initial voltage, N6900 internal counter will start counting.
The counter will stop working until the battery voltage drops
to cut-off voltage.Exhibitions For more
