The N69200 series adopts an ultra-high power density design, and NGI has developed a unique heat dissipation structure, which enables the standard 19 inch 3U chassis to have a power of up to 6kW, half the volume of traditional electronic loads, and a 100% improvement in heat dissipation performance. Its weight is only 50% of traditional electronic loads.

Parallel connection of master/slave, multi power combination

The N69200 series supports parallel connection of master/slave and can actively share current. When the load power demand increases, all models with the same voltage specification can achieve the required current and power through parallel connection (master+master, master+slave). When using the N69200 series products, users only need to program the load current on the host load, and the slave load can be automatically distributed, further simplifying the user operation steps.

Multiple working modes, suitable for various testing scenarios

The N69200 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 N69200 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 N69200 series offers programmable dynamic loads up to 30kHz (CCD dynamic current mode, CVD dynamic voltage mode, CRD dynamic resistance mode, CPD dynamic power mode), dynamic variable frequency sweep mode, and more. The programmable dynamic load mode can set high/low position, rising/falling slope, duration, execution times, etc. The voltage and current sampling rate of the dynamic frequency conversion scanning mode is 500kHz, supporting linear changes in the frequency of the load current, with a maximum frequency of 30kHz. This mode can measure the peak voltage Vpk+, valley voltage Vpk -, and frequency points of the measured object during the dynamic frequency conversion load change process.

Charge and discharge testing, built-in battery testing mode

The N69200 series electronic load panel is equipped with a battery testing mode, which allows for easy setting of cut-off conditions for battery discharge 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, power OCP testing is faster

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 will increase the pulling current until the voltage is lower than the cut-off voltage or reaches the maximum pulling current.

Equivalent DC internal resistance testing function (optional)

Equivalent Direct Current Resistance (ESR) is an important technical indicator for measuring the performance of batteries (supercapacitors). The N69200 series load provides professional DCIR measurement function, which has the advantages of accurate measurement results and stable repeated measurement results. The DCIR measurement function uses constant current mode to load the measured object. At the moment of current change, the N69200 professional internal resistance sampling circuit can accurately capture the voltage drop of the measured object. According to Ohm's law, the equivalent DC internal resistance can be calculated.
