The Keysight N3305A is a 500 W (0-60A, 0-150V) electronic load module for use in either the N3300A or N3301A electronic load mainframe in system applications. The N3305A load module is fast and accurate, for programming in constant current, constant voltage, or constant resistance modes, or for making voltage, current or power measurements. The N3305A can also digitize waveforms.

The N3300 Series supports up to six channels, each with a unique maximum voltage and current. They allow the design of a flexible automated test equipment (ATE) system to verify many types of power supplies, DC-to-DC converters, and batteries. Add additional modules to test multiple power sources simultaneously. Each module includes a 16-bit voltage, current, and power measurement system.
