Features and advantages

Ultra high speed response, μ s level response load

The N67000 series has a single machine current loading speed of up to 60A/μ s and a multi machine parallel slope of over 100A/μ s, meeting the testing needs of sensors, AI chips, high-speed switching power supplies, and other scenarios. In power testing, the N67000 series' fast response capability ensures the accuracy of test results when the power supply needs to quickly adjust its output to meet load changes. In the testing system, the N67000 series can more accurately simulate load changes under actual working conditions, thereby providing a more realistic testing environment.

Parallel connection of master/slave, multi power combination

The N67000 series supports master-slave parallel connection and can actively share current. When the load power demand increases, the required current and power can be achieved through parallel connection (master+slave).

Multiple working modes, suitable for various testing scenarios

N67000 not only supports the conventional four working modes of CC, CV, CP, and CR, but also has four combined working modes of CV+CC, CR+CC, CV+CR, and CP+CC to cope with changes in load characteristics during actual testing. CR+CC is suitable for power on testing to prevent overcurrent protection during power on; CV+CR can replace the application of Von point setting; CV+CC can simulate the working mode conversion process of battery charging, and users can choose different working modes for testing according to their actual situation.

High speed dynamic mode with dynamic frequency conversion scanning

The N67000 series has a high-speed dynamic mode, which simulates the dynamic load behavior of the power supply through the dynamic mode and can test the dynamic characteristics of the DC power supply. The N67000 series offers programmable dynamic loads (CCD dynamic current mode, CVD dynamic voltage mode, CRD dynamic resistance mode, CPD dynamic power mode), dynamic variable frequency sweep mode, and more. Programmable dynamic negative

charge-discharge test

The N67000 series electronic load panel is equipped with a battery testing mode, which allows for easy setting of cut-off conditions for battery charging and discharging on the panel. Local control can meet the automated charging and discharging testing of the battery. For example, when the battery voltage is lower than the user set starting voltage, the internal timer starts counting until the battery voltage drops to the user set ending voltage, and the timer stops counting.

Overcurrent protection testing function

The load provides a rising ramp current to test whether the voltage of the tested device can reach the termination potential, in order to determine whether the OCP protection is normal. This test checks the output response of the tested device under overload conditions.

During OCP testing, the load is pulled in constant current mode and the voltage of the tested object is checked to ensure it is below the cutoff voltage. If the voltage of the tested object is lower than the cut-off voltage, record the current under load as the test result, turn off the input, and stop the test; If the voltage of the tested object is higher than the cut-off voltage, the load increases the pulling current until the voltage is lower than the cut-off voltage or reaches
