N62400 Series Low Voltage High Current DC Electronic Load

N62400 series is developed based on NGI's years of experience in testing for fuel cell. It is with high accuracy, high reliability and high cost performance. N62400 can load high current under ultra-low voltage. The minimum operating voltage when loading 1200A can be low to 0.2V. It is designed in a 19 inch 3U chassis, which is available for benchtop use or installation in 19 inch rack.

Loading current at ultra-low voltage
The output voltage of a single fuel cell gradually decreases as the current increases, which requires the test equipment to be able to load high current at ultra-low voltage. N62400 3U standalone supports a maximum input of 600A, and the minimum operating voltage is 0.2V@600A, which can realize the characteristic test for almost all voltage points in the single fuel cell test process, and can fully display the current of fuel cell in the entire voltage range, so as to provide sufficient data for the performance study of fuel cells.
