NGI N6900 600V/30A/3000W DC Programmable Electronic Load Tester

Product Details

N6900 Series Distributed High Power DC Electronic Load

Product Introduction
N6900 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.

Dynamic mode
N6900 series provides three options for dynamic: continuous, toggle and pulse. The dynamic rate is up to 20kHz and can be adjustable. This function is often used to test power supply transient performance, battery protection board protection performance and battery pulse charging.

Auto test function
The 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.

Charge& discharge test
Users 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.
