Keysight N2779A 1<\/figcaption><\/figure>\n

Overview<\/h2>\n

The Keysight N2779A Power Supply is a precision-engineered accessory designed to provide clean, low-noise DC power for Keysight N2780\u201383A\/B AC\/DC current probes. Unlike standard laboratory power supplies, the N2779A is purpose-built to ensure optimal probe performance, measurement stability, and operator safety in high-precision testing environments.<\/p>\n

Equipped with three independent \u00b112 V outputs, the unit enables simultaneous operation of up to three current probes, making it particularly suitable for three-phase power measurements in power electronics, motor drives, and energy systems.<\/p>\n

Its universal AC input capability (100\u2013240 VAC, 50\/60 Hz) ensures global compatibility across laboratories and industrial facilities.<\/p>\n
