Low voltage with load function

The IT8900G/L series has ultra-low on-resistance and two operating ranges, the 150V model has an internal resistance of about 0.7mΩ, and the lowest single-unit on-load voltage is <0.1V in the small-range gear, which can carry a load of 60A, and 0.75V can carry a load of 600A. It is especially suitable for testing fuel cells, supercapacitors, solar cells, DC-DC converters, and other low-voltage, high-current electronic devices. It is especially suitable for testing fuel cells, supercapacitors, solar cells, DC-DC converters and other low-voltage high-current electronic devices.

CC dynamic mode up to 30kHz

The IT8900G series electronic loads (150V models) feature dynamic modes up to 30kHz*, and the upgraded, integrated internal structure has dramatically improved loop response and stability. They can be used for testing the transient response of switching power supplies, as well as testing the instantaneous high-current tolerance of DC-DC converters and batteries.
