|Summary

     Ultra-low voltage and high current DC electronic load is a highly reliable and high performance electronic load developed on the basis of FT conventional electronic load for fuel cell testing, CPU power supply testing and other low-voltage and high-current testing scenarios. For different current levels, this product contains two series: NZ, N. Its voltage is 0-20V or 40V, of which the NZ series can be -2.4V full-current load, and the N series is ultra-low voltage full-current load. The maximum load capacity is up to -2.4V@1200A and 0.2V@5000A, which is an excellent choice for your test with high precision and high cost performance.

|Ultra low voltage full current load

Ultra-low voltage and high current DC electronic load with ultra-low internal resistance, the smallest internal resistance <0.2mΩ. FT68203N-20-1000 can carry 1000A of current at 0.2V input with a power of only 3kW, which is only one-eighteenth of the power of an ordinary electronic load under the same low-voltage loading conditions. The smaller test power can provide larger test current, which can greatly reduce the test cost in fuel cell membrane electrode, monolithic cell and short stack test.

|Battery capacity testing

In order to facilitate battery testing, the electronic load provides a battery capacity test function. Battery test includes: battery internal resistance test and battery capacity test. Battery capacity test adopts constant current mode to discharge. During the discharge process, the load automatically records the voltage, current, time, AH and other parameters.

|Sequence functions

The electronic load provides sequence test function. Users can edit the test sequence of a load by themselves to simulate various changes of the load input, suitable for all kinds of complex load testing.

|Constant state function

The electronic load has four test modes: constant current, constant voltage, constant resistance and constant power, which can meet a wide range of test requirements. Constant current and constant resistance modes can be used to test whether the output voltage maintains a stable output under different load conditions. For battery chargers and adapters, the Constant Voltage mode varies the output voltage of the charger and adapter to verify that the output current is correct.

|-2.4V input full current carry

NZ series can be loaded with full current at 0V input. The low-voltage and high-current load characteristics provide a strong advantage in fuel cell, battery forced discharge, and CPU power supply system testing.
