Low voltage loading

The IT8900G/L series has an ultra-low on-resistance and two operating ranges, the 150V model has an internal resistance of about 0.7m Ω, and the lowest single-unit on-load voltage is < 0.1 V for 60 A input at the low range, and 0.75 V for 600 A. It is particularly suitable for testing fuel cells, supercapacitors, solar cells, DC-DC converters, and other low-voltage, high-current electronic devices.

Dynamic mode up to 30kHz

The IT8900G series electronic load (150V models) features dynamic modes up to 30kHz*. The upgraded all-in-one internal structure allows the it to dramatically improve loop response and stability. It 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.

*Dynamic response of IT8900L is 10kHz.
