Keysight Technologies (Agilent HP) Power Supplies

Keysight’s offerings split into distinct use cases rather than a single linear product line. At the bench level you will find compact, standalone supplies and multi‑output bench models with built‑in meters and local controls. For system and ATE integration there are low‑profile modular mainframes that accept a variety of N67xx modules. For higher continuous power and rack integration there are single‑output system supplies rated from hundreds of watts up into multi‑kilowatt classes. Companion products include electronic load modules in N3300 mainframes and AC sources/power analyzers for AC or DC+AC test scenarios.

Examples to illustrate the structure

• Bench and small system instruments: E3600 and related benchtop models (for compact single‑ and multi‑output needs). The E3631A is an example of a compact triple‑output design used for lab work. The E3633A shows the dual‑range, higher‑power benchtop approach.
• Modular mainframe approach: the N6700 Series accommodates multiple N67xx class modules for flexible channel count and channel mix.
• High‑power single‑output systems: the 66xx and 68xx series units provide single outputs at much higher power and current for burn‑in and production test.

Use these attributes to decide which family fits your requirements:

• Form factor and density: modular mainframes are chosen when you need multiple isolated channels in a compact chassis; rack/system single‑output units are for high continuous power per channel; benchtop units are for standalone lab use.
• Interfaces and automation: many Keysight system and benchtop models offer digital remote interfaces (GPIB, LAN, USB, RS‑232) and SCPI command support; modules rely on the mainframe for communications. Where instrument control must be integrated into test sequences, prefer units or mainframes that list GPIB/LAN/USB.
• Power and autoranging: autoranging supplies maintain a power envelope across a broad V/I combination; some system supplies and autoranging models are more appropriate when a wide V–I operating envelope is required, while fixed‑range supplies give simpler, often higher‑current outputs at a single voltage range.
• Measurement and precision: module‑based solutions such as the N6750, N6740 and N6760 classes are specified for low noise, fast programming and high readback accuracy when you need measurement‑grade outputs within an N6700 system.

Illustrative models and their roles

• N6700 Series mainframes host N6730/N6740/N6750/N6760/N6770 modules when a mix of precision, power and autoranging channels is needed in one chassis.
• N5700 Series (750W and 1500W variants) are compact system supplies intended where a single, higher‑power programmable DC output is required in a rack slot.
• 66xx and 67xx system series (for example 6640, 6650 or 6670) cover the middle to high power single‑output system market where built‑in measurements and digital interfaces are expected.

Match the supply to the task using these practical criteria:

• Channel count and isolation: choose a modular N6700 approach when you need multiple isolated outputs and centralized communication. Modules (N6730/N6740/N6750/N6760/N6770) give per‑slot flexibility.
• Total and per‑channel power: for multi‑kW single outputs consider the higher‑power 66xx/67xx/68xx series; for compact rack density choose the N5700 750W or 1500W variants depending on power per rack unit.
• Programmability and interfaces: if automated control is required, explicit GPIB/LAN/USB or RS‑232 support matters — many system and bench models list those interfaces; modules rely on mainframe link interfaces.
• Measurement needs: when low noise and tight readback accuracy are required, opt for the high‑performance N67xx class modules intended for the N6700 platform.

Also consider complementary equipment: Keysight N3300A mainframes and N330x electronic load modules support dynamic load testing, and AC source/analyzer models such as 6812B/6813B are available when AC or combined DC/AC testing is required.
