The Keysight N3300A electronic load mainframe accepts user-installable Keysight load modules for easy system configuration and future reconfiguration. The N3300A holds up to six N3302A, N3303A, and N3304A load modules, or three N3305A and N3306A load modules, allowing up to 1,800 watts of total maximum power. One GPIB address is all you need for complete control and readback of all load modules within a single mainframe. The N3300A Series of dc electronic loads provides the fast operation and accurate programming and readback needed for high-volume dc power supply test systems.

The Keysight N3300A mainframe has six slots. The 150 watt, 250 watt, and 300 watt modules require one slot each. The 500 watt and 600 watt modules require two slots each. Any combination of modules can be used, up to using the full six slots. The half-rack width mainframe, the Keysight N3301A, has two slots.
