KEYSIGHT TECHNOLOGIES N6791A STATIC SMOOTH DRUM ROLLER

Technical Description

The Keysight N6791A is a DC electronic load module designed for integration with the N6700 series modular mainframes. It supports a voltage range from 0 to 60 V and a current range from 0 to 40 A, delivering a maximum power dissipation of 200 W (0.268 horsepower). The device features programmable accuracy for current at both high range (0.04% at 20 A/40 A) and low range (0.04% at 2 A/4 A), voltage accuracy of 0.03% at 60 V, and power accuracy of 0.06% in both high (100 W/200 W) and low (10 W/20 W) power ranges. It supports precise current settings including 40 A at 1.6 V, 25 A at 1.0 V, 12.5 A at 0.5 V, and 2.5 A at 0.1 V, enabling detailed load simulations for various testing scenarios. This module operates in multiple modes such as constant voltage, constant current, constant resistance, and constant power, with advanced control and digitization capabilities, allowing accurate and dynamic load emulation. The compact 1U single-wide form factor facilitates flexible system configurations with up to four modules per mainframe. Typical applications include component and power supply testing, validation, and characterization in research and development or manufacturing environments where precise electronic load control and accurate power measurement are critical. The high programming accuracy combined with a wide range of operating parameters offers engineers reliable performance and versatility in electronic load testing setups.
