The Keysight AC6800B Series is a family of basic AC power sources designed to deliver stable, dependable AC power for bench testing and production-line applications. The series comprises four single-phase models — the AC6801B at 500 VA, AC6802B at 1000 VA, AC6803B at 2000 VA, and AC6804B at 4000 VA — each providing AC output up to 310 Vrms with frequency selectable from 40 to 500 Hz, along with a DC output mode extending to 438 V.

Applications listed by the manufacturer include simulating global AC power conditions, testing varying frequency and voltage combinations to replicate real-world power environments, and power factor correction testing along with similar AC+DC applications such as evaluating input circuitry for ripple voltage. Typical use cases identified for the series include testing universal power supplies designed for global deployment, supplying single-phase 400 Hz power for avionic electronics development, manufacturing, and repair, and verifying commercial LED drivers and fluorescent ballasts at voltages up to 310 VAC — suitable for electronics rated to 277 VAC ±10%.

ValueTronics International, LLC operates a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where AC power source inventory is stored and tested before shipment. Unlike drop-ship resellers or pass-through brokers who never take physical possession of the instruments they list, ValueTronics handles every unit on-site — confirming functionality, verifying accessory completeness, and grading condition prior to listing. This in-house process is particularly relevant for programmable AC sources like the AC6800B Series, where the analog interface board option, GPIB interface board option, and rack-mount kit availability vary unit-to-unit and require physical verification rather than label inspection.

Brand Heritage

Keysight Technologies originated as the test and measurement division of Hewlett-Packard, which spun off as Agilent Technologies in 1999 before further dividing in 2014 when the electronic measurement business became Keysight Technologies. AC6800B Series instruments carry the Keysight brand and reflect this engineering lineage in the family of bench AC sources, signal sources, and power supplies traceable to HP's original instrumentation work.

Compare Other Models in This Series

The Keysight AC6800B Series consists of four single-phase basic AC power source models that share the same voltage range (1–310 Vrms AC, to 438 V DC), the same frequency range (40–500 Hz), the same measurement capabilities, and the same standard LAN/LXI Core and USB interfaces. The models differ primarily in maximum output power capacity and corresponding maximum rms current — allowing customers to select the appropriate VA rating for their device under test without changing the operating envelope, control interface, or measurement framework.

Across the series, the AC6801B at 500 VA serves single-device bench testing, the AC6802B at 1000 VA accommodates higher-current consumer electronics and ballast verification, the AC6803B at 2000 VA supports industrial loads, and the AC6804B at 4000 VA addresses the largest single-phase test applications within the family. All four models share the same accuracy specifications, the same optional analog interface board (AC68BALGU), the same optional GPIB interface (AC68GPBU), and the same compliance certifications.

Each new model in the AC6800B Series is listed on its own dedicated product page with model-specific pricing and availability. Use the comparison information below to identify which power capacity matches your device under test before navigating to the specific model page.

The primary differences across the four models are maximum output power, maximum rms current, and physical size. Voltage range, frequency range, AC and DC output modes, accuracy specifications, interface options, and protection features are identical across all four models. The AC6801B is the most compact at approximately 8 kg, while the AC6804B is approximately 31 kg and uses a different chassis form factor with four cooling fans to support its 4000 VA rating. Maximum repetitive peak current scales proportionally with model size, providing approximately three times the rms current rating in each case.

Input requirements also differ across models. The AC6801B uses an IEC 320 inlet and ships with a standard power cord (region-dependent), while the AC6802B, AC6803B, and AC6804B use M4 or M6 terminal blocks for input connections and do not include a power cord. Refer to the comparison table for the complete spec-by-spec breakdown including input current draw, output ratings, and physical dimensions for each model.
