Benchtop DC Power Supplies
For general laboratory use, circuit development, and manual testing, Keysight provides several single- and multi-output benchtop families. The Keysight Technologies (Agilent HP) E3600 Series - 30-60W and the Keysight Technologies (Agilent HP) E3640 Series - 30-80W provide low-noise, linear regulation. For simple manual tasks, the non-programmable Keysight Technologies (Agilent HP) U8000 Series - 90-150W features front panel binding posts and does not include digital programming interfaces.
Multi-output options allow engineers to power complex circuits from a single chassis. The Keysight Technologies (Agilent HP) E3630A provides a 35 W triple-output manual configuration with auto-tracking ±20 V outputs, while the Keysight Technologies (Agilent HP) E3631A is a programmable triple-output alternative with GPIB and RS-232. For isolated dual-channel setups, the Keysight Technologies (Agilent HP) E3620A supplies up to 50 W across two independent channels.
High-Density Modular Power Systems (N6700 Series)
For applications requiring high channel density or varying performance characteristics, the Keysight Technologies (Agilent HP) N6700 Series - Mainframes and Systems houses up to four modules in a compact 1U form factor. The system supports a mix-and-match approach using several module families:
- Basic Modules: The Keysight Technologies (Agilent HP) N6730 Series - 50W Modules, Keysight Technologies (Agilent HP) N6740 Series - 100W Modules, and Keysight Technologies (Agilent HP) N6770 Series - 300W Modules provide economical programmable power for standard applications.
- High-Performance Modules: The Keysight Technologies (Agilent HP) N6750 Series - 50W, 100W, 300W Modules add fast programming speeds and autoranging capability.
- Precision Modules: The Keysight Technologies (Agilent HP) N6760 Series - 50W, 100W Modules provide high-accuracy voltage and current sourcing along with microampere-level readback measurements.
System DC Power Supplies
When high power or rack-mount system integration is required, Keysight offers robust single-output platforms. The Keysight Technologies (Agilent HP) N5700 Series - 750W and Keysight Technologies (Agilent HP) N5700 Series - 1500W units deliver high power density in 1U and 2U formats, with standard GPIB, LAN, and USB connectivity.
For legacy architectures and specialized automated test environments, the 6600 and 6500 series provide isolated outputs. System units like the Keysight Technologies (Agilent HP) 6640 Series - 200W, Keysight Technologies (Agilent HP) 6650 Series - 500W, and high-power Keysight Technologies (Agilent HP) 6670 Series - 2000W feature standard digital interfaces (GPIB/RS-232). For installations using external analog controllers or PLC systems, corresponding families like the Keysight Technologies (Agilent HP) 6540 Series - 200W, Keysight Technologies (Agilent HP) 6550 Series - 500W, and Keysight Technologies (Agilent HP) 6570 Series - 2000W omit standard digital interfaces in favor of dedicated analog programming. To maximize flexibility under varying load profiles, the Keysight Technologies (Agilent HP) 6032A and Keysight Technologies (Agilent HP) 6010 Series - 1200W utilize autoranging architectures to maintain maximum power output over a broad voltage and current envelope.
AC Power Sources and DC Electronic Loads
In addition to standard DC supplies, the catalog includes AC sources, electronic loads, and highly specialized transient test equipment. For mobile communications test, the Keysight Technologies (Agilent HP) 66300 Series - 40 - 100 W offers built-in battery simulation and dynamic current measurement capabilities designed for cellular and wireless hardware.
For power-supply validation, the Keysight Technologies (Agilent HP) N3300A mainframe accepts up to six DC load modules, such as the 150 W Keysight Technologies (Agilent HP) N3302A, the 300 W Keysight Technologies (Agilent HP) N3304A, and the 600 W Keysight Technologies (Agilent HP) N3306A modules, operating in constant current, voltage, or resistance modes. On-bench testing can also utilize the standalone Keysight Technologies (Agilent HP) 6060B 300 W electronic load. AC stimulation and measurement requirements are served by the Keysight Technologies (Agilent HP) 6812B (750 VA) and Keysight Technologies (Agilent HP) 6813B (1750 VA) AC power source and analyzers.
