Safety Considerations

This electronic load is a Safety Class 1 instrument, which means it has a protective earth terminal. That terminal must be connected to earth ground through power source equipped with a ground receptacle. Refer to the Safety Summary page at the beginning of this guide for general safety information. Before installation or operation, check the electronic load and review this guide for safety warnings and instructions. Safety warnings for specific procedures are located at appropriate places in the Guide.

Description

The N3300A is a DC Electronic Load Mainframe used for design, manufacturing, and evaluation of dc power supplies, batteries, and power components. Other applications include use as a power circuit breaker or crowbar, high current function or pulse generator, fuel-cell and photovoltaic cell test, and de-energizing superconducting magnets.

The mainframe contains six slots for load modules. Load modules occupy either 1 or 2 slots depending on the power rating of the module. The mainframe can dissipate up to 300 watts per slot, to a total of 1800 watts for a fully loaded mainframe. Each individual module has its own channel number and contains its own input connector. The mainframe contains a processor, GPIB connector, RS-232 connector and interface circuits, trigger circuits, front-panel keypad and display, and other circuits common to all the load modules.
