AC6903H Overview

The Keysight AC6903H is a three-phase AC power source from the AC6900 Series. It offers a total power range of 3 kVA, rms current 30 A / 15 A or 10 A / 5 A and supports RMS voltages up to 320 V. The frequency capability extends up to 5 kHz. The AC6903H can operate in AC, DC, or AC plus DC mode, making it versatile for various testing scenarios. It includes built-in tests for power line disturbance, output sequencing, and harmonic analysis. Additionally, it features waveform generation capabilities. The AC6903H is particularly useful for avionic equipment testing. It simplifies pre-compliance testing using the PathWave avionics test suite. The AC6900 Series combines the functionalities of a multimeter, harmonic analyzer, and power analyzer in a single instrument, providing accurate and precise testing capabilities.

The AC6900 Series of 3-Phase AC Power Sources

The escalating need for testing avionics equipment (avionic electronic systems), such as air traffic control systems, sensors, and unmanned aircraft systems, calls for an advanced AC and DC power solution. An ideal remedy for this objective is a compact, high-efficiency AC power source with DC functionality like the AC6900 Series. Toss in an avionics testing software suite such as BV0028B to expedite pre-compliance testing for both commercial and military standards and the result is an optimal instrument anyone would highly value.

Now given that your product will operate in real-world scenarios where AC power can be unpredictable, it's essential to design and validate its performance under a broad range of AC power inputs. This includes conditions like brownouts, dropouts, sags, and other irregularities that are not uncommon in many industries today. On top of that, it's necessary to conduct tests for line voltages and frequencies to ensure your product complies with the regulatory requirements of the country where you intend to market it.

Keysight's compact AC6900 Series 3-phase AC power sources are equipped with the features needed to easily achieve your testing objectives, whether in a research and development setting or on the manufacturing test floor. This series offers a comprehensive AC and DC power solution by integrating the functions of a multimeter, harmonic analyzer, and power analyzer into a single device. It allows for the easy generation of DC power, either standalone or as a DC offset to an AC waveform. Overall, it's the optimal instrument for testing avionics equipment operating at nominal frequencies of 400 Hz, 800 Hz, or up to 5,000 Hz, in compliance with RTCA DO-160 and MIL-STD-704 standards, which include both AC and DC immunity tests.
