The Keysight Series N5700 is a family of general-purpose System DC power supplies built in a 1U (single rack-unit) high switching design and offered with a wide variety of output voltage and current ratings. Every model is power-factor corrected and operates from a worldwide AC voltage range. Output voltage and current are displayed continuously on the front panel, while LED indicators report the complete operating status of the supply. The front-panel controls let an operator set the output parameters along with over-voltage, under-voltage, and over-current protection levels, and preview those settings before applying them.

As a general-purpose programmable supply, the Series N5700 delivers controlled DC power to a device under test on the bench, in a rack, or within an automated test system. The rear panel carries the connectors needed to control and monitor operation through analog signals or through the built-in remote communication interfaces, which suits the supply to automated measurement setups. Where a single unit cannot meet a requirement, supplies of the same rating can be operated in parallel for higher current or in series for higher voltage, and connection schemes for multiple loads, inductive loads, and external voltage sources such as batteries are all addressed in the connection guidance.

ValueTronics keeps the Series N5700 in stock at our own 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we hold and manage our inventory directly. Either way, the instrument you order is backed by people who know test-and-measurement equipment and stand behind what leaves the building.

Brand Heritage

The instruments in this line carry the Keysight Technologies name, the product of a well-documented corporate history. Hewlett-Packard's test and measurement business was spun off as Agilent Technologies in 1999, and Agilent's electronic measurement business became Keysight Technologies in 2014.

Compare Other Models in This Series

The Series N5700 is a family of general-purpose, 1U-high switching DC power supplies offered in two power classes — 750 W and 1500 W — and across a broad selection of output voltage and current combinations. All models share the same architecture: a power-factor-corrected universal AC input, continuous front-panel display of output voltage and current, LED status indication, and built-in GPIB, LAN, and USB remote interfaces.

Because the models differ chiefly in their rated output voltage, current, and power, the family lets a buyer choose the specific voltage-and-current envelope an application needs while keeping a consistent control interface, form factor, and protection feature set across every unit.

Each new model in the Series N5700 is listed below on its own dedicated product page with condition-matched pricing. Compare the voltage, current, and power ratings to identify the model that fits your application, then open that model's page for its specifications and availability.

The models in the Series N5700 are distinguished primarily by output voltage rating, which spans from 6 V at the low end to 600 V at the high end, and by power class. Within a given power class the available current scales inversely with voltage — the 750 W tier delivers its highest current on the lowest-voltage model and its lowest current on the highest-voltage model — while the 1500 W tier provides correspondingly higher current at the same voltages.

The comparison table below lists each model's rated output voltage, output current, and power so the differences can be read at a glance. Apart from these output ratings, the models share the same control interfaces, protection functions, and mechanical format, so model selection comes down to matching the required voltage and current to the appropriate row.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Accessories Supplied

• Power cord appropriate for your location (terminated)
• DB25 subminiature analog connector plug for analog control connections
• Shield assembly for the output terminal connections
• Certificate of Calibration referenced to the serial number

Product Core & Specifications

Important: Only power supplies with identical voltage and current ratings can be connected in parallel or in series.

Important: Output terminal isolation: For models up to 60 VDC rated output, no point on the output may be more than ±60 VDC above or below chassis ground. For models greater than 60 VDC rated output, no point on the positive output may be more than ±600 VDC, and no point on the negative output more than ±400 VDC, above or below chassis ground.

Important: Shock hazard: Hazardous voltages may exist at the outputs and the load connections when using a power supply with a rated output greater than 60 V. Ensure that the load and its connections have no accessible live parts and that load wiring insulation is rated for the maximum output voltage.

Important: Fire hazard: Use only the power cord that was supplied with your instrument. Using other types of power cords may cause overheating of the power cord, resulting in fire.

Important: 1500 W units: Connection of this power supply to an AC power source should be made by a qualified electrician or other qualified personnel (the AC input is a 3-terminal wire clamp).

Important: The instrument contains an internal fuse, which is not customer accessible.

Important: Inductive loads can produce voltage spikes that may be harmful to the power supply; connect a diode across the output rated greater than the power supply's maximum output voltage and current.

Important: Do not operate the power supply where the ambient temperature exceeds 40 °C. Above 2000 m, derate the output current by 2%/100 m and the maximum ambient temperature by 1 °C/100 m.

Important: N5772A maximum output current is listed as 0–2.5 A on the front-panel Model Ratings table but 2.6 A in the Appendix A performance specifications; the conservative 2.5 A value should be assumed unless the specific unit is verified.

Recommended pairing: the N5740A rack-mount slide kit installs the supply on slides in a standard 19-inch equipment rack.
