The Agilent N6700 Low-Profile Modular Power System (MPS) is a 1U-high, multiple-output programmable DC power supply system that gives test system integrators the flexibility to mix and match from over 30 different DC power and electronic load modules. The result is a 1- to 4-channel DC power system that can be optimized to match a specific set of test requirements, letting engineers invest in high-performance outputs where speed and accuracy matter and basic outputs where simple DC power is all that is needed. Built on an advanced switching power supply design that fits within 1U of rack space, a single mainframe holds one to four modules.
The N6700 MPS is built for automatic test equipment (ATE) systems in R&D, design validation, and manufacturing. Power supplies are a fundamental component of test systems across aerospace and defense, consumer electronics, computers and peripherals, communications, semiconductor, and automotive electronics — industries where complex ATE systems often require multiple power sources and where reducing occupied rack space and increasing test throughput are constant pressures. Within the family, precision modules are suited to semiconductor and passive device testing where a precisely controlled output and highly accurate measurements are needed, while the source/measure unit modules support applications such as battery drain analysis and functional test.
ValueTronics stocks and holds its own test-and-measurement inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Keeping inventory on hand and verifying used units in our own facility means an order can be filled quickly and with confidence in the unit's condition.
These instruments are branded Agilent Technologies. Agilent Technologies was formed in 1999 as a spin-off of Hewlett-Packard's test and measurement business; that electronic measurement business was subsequently established as Keysight Technologies in 2014, the brand that carries this product line forward today. Equipment bearing the Agilent name reflects this period of the brand's corporate history.
The N6700 Modular Power System is a single 1U platform built around three low-profile mainframes — the 400 W N6700B, the 600 W N6701A, and the 1200 W N6702A — each able to hold one to four DC power modules. Rather than a fixed-configuration supply, it is a user-reconfigurable system: integrators select from over 30 modules to assemble exactly the channel count, voltage, current, and performance grade a test station calls for. The system can be purchased as a mainframe plus separate modules for self-assembly, or as a build-to-order N6710B, N6711A, or N6712A system shipped fully assembled.
The same module catalog also runs in the N6705 DC Power Analyzer mainframe, a modular instrument that sources and measures DC voltage and current into a device under test. The N6705 combines one to four DC power supply or electronic load modules with the functions of a digital multimeter, oscilloscope, arbitrary waveform generator, and data logger in a single integrated unit, giving R&D engineers insight into a device's power consumption without writing a single line of code — all sourcing, loading, and measurement functions are available directly from the front panel. Because the same modules run in both the low-profile ATE mainframes and the bench analyzer, test correlation and program sharing between R&D and manufacturing are possible. The N6705B is the four-slot analyzer ordered together with separately boxed modules you assemble yourself; the N6715B is the build-to-order configuration shipped as one mainframe with one to four installed modules.
The modules themselves fall into distinct series — basic DC power (the N6730, N6740, and N6770 ranges), high-performance autoranging (N6750), precision (N6760), source/measure units (N6780), application-specific (N6783A), and electronic loads (N6790) — so a single mainframe can combine a high-power autoranging output with several economical basic outputs. A power module's available capabilities depend not only on its own hardware but also on the hardware and firmware of the mainframe in which it is installed.
Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the mainframe or module that matches your channel count, output rating, and interface needs, and review that page for its specific specifications and availability.
The mainframes differ chiefly in total available output power — 400 W, 600 W, and 1200 W for the N6700B, N6701A, and N6702A respectively — and only the 1200 W frame offers automatic AC-line power scaling: it senses the available AC line at turn-on and limits output to 600 W so a high-power mainframe can be plugged into any standard outlet, drawing full power only when operated at the higher (200–240 VAC) AC input. Output sequencing can be synchronized between multiple units by wiring the rear-panel I/O ports together, a capability supported on the N6700B, N6701A, and N6702A mainframes.
Among the modules, the differences are output rating (from 18 W up to 500 W), voltage and current range, ripple and noise, programming and measurement accuracy, and performance class. Basic modules cover programmable DC power at 50 W, 100 W, and 300 W with outputs up to 150 V and up to 20 A; high-performance autoranging and precision modules add autoranging outputs, lower noise, and faster voltage changes, reaching up to 500 W, 60 V, and 50 A, with the precision series adding low ranges, dual programming and measurement ranges, and 16-bit programming / 18-bit measurement precision with simultaneous voltage and current digitizing. Application-specific source/measure units provide up to 80 W with two- or four-quadrant operation and measurements down to nanoamperes, and the N6790 electronic loads offer 100 W and 200 W modules (up to 60 V and 40 A) with constant voltage, current, resistance, and power modes. The 300 W and 500 W autoranging and precision modules each occupy two of the four module slots. The comparison table below lays out the mainframe ratings side by side so the right configuration can be matched to each requirement.

Important: DC power and electronic load modules are not standalone instruments; they require an N6700-series (N6700B/N6701A/N6702A) or N6705 DC Power Analyzer (N6705A/N6705B) mainframe and are ordered separately. At least one module is required for the system to function, and a module's basic capabilities depend on the hardware and firmware of the mainframe in which it is installed.
Important: Each module occupies one module slot, except the double-wide modules N6753A–N6756A, N6763A–N6766A, N6785A–N6786A, and N6792A, which each occupy two of the four mainframe slots.
Important: Installing a 500 W module in the 400 W N6700B mainframe may prevent that module from running at its full rated output power. The mainframe's power management feature allocates available power to the outputs where it is needed when the sum of installed module power exceeds the mainframe's total available output power.
Important: When configuring a mainframe with fewer than four filled module slots, you must order a filler panel kit (N6708A); each kit contains three filler panels, and every empty module slot must be filled with a filler panel for proper operation.
Important: Rack mounting requires the Rack Mount Kit (option 908 / N6709A); standard rack mount hardware, rails, or slides will not work and are not compatible with the N6700 because of its 1U size and airflow requirements.
Important: For model N6702A (and the N6712A system), the maximum output power is limited to 600 W at 100–120 VAC; to achieve full output power of 1200 W you must use option 929 and operate at 200–240 VAC. AC mains circuits rated 100–180 VAC cannot supply enough current to power the N6702A at its full rated power; on such a mains, internal circuits limit the power available to modules to 600 W maximum.
Important: Output sequencing synchronization across multiple mainframes is supported on the N6700B, N6701A, and N6702A mainframes; it is not supported on the discontinued N6700A mainframe. Option LGA (large-size FPGA) must be ordered on the N6751A and N6752A modules, as it is required to support output sequencing between multiple mainframes.
Important: Option 760 (Output Disconnect/Polarity Reversal Relays) is not available on Models N6741B, N6751A, N6752A, N6761A, N6762A, and N6781A–N6784A, and limits the output current to 10 A maximum on Models N6742B and N6773A. Option 2UA (200 µA measurement range) is available only on Models N6761A and N6762A.
Important: Output terminal isolation: no output terminal may be more than ±240 VDC from any other terminal or chassis ground. When using the auxiliary measurement input terminals on the N6781A, no output or input terminal may be more than ±60 VDC from any other terminal and chassis ground. Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705.
Important: Front-panel binding posts are rated for 20 A per post; modules with outputs rated greater than 20 A, such as the N6753A or N6792A, route their high-current wiring through the N6705 rear panel (the N6705B provides rear-panel access ports; for an N6705A mainframe, order N6705U-057 to replace the rear panel).
Important: N6783A modules cannot be used in series with other N6783A modules or any other N67xx module. When sinking power, Model N6784A can operate at the maximum rated output power for only a limited time; the unit monitors internal power-device temperature and latches the output off if the safe limit is exceeded (annunciated by the OT status bit), after which a protect clear is required to resume operation.
Important: New modules N6753A and N6754A require mainframe firmware version C.02.00 or greater. If you add modules with model numbers N673xA, N673xB, N674xA, N674xB, N6753A, N6754A, or N677xA to an N672xA, you will not be able to access the Agilent 662x command set for any installed modules; only SCPI commands will be accepted.
Important: Published current/power ratings for Models N6751A and N6752A differ between the datasheet's specification table (N6751A 50 V/5 A/50 W, N6752A 50 V/10 A/100 W) and the ordering tables (both listed as 50 V/1.5 A/50 W); confirm the installed module's rating from the instrument before relying on maximum output. Performance specifications for the N6780 Series 2-quadrant SMU modules (N6781A, N6782A) are not included in this data sheet — see the N6780 Series Source/Measure Units (SMUs) Data Sheet, literature number 5990-5829EN.
Recommended pairing: the Agilent 14585A Control and Analysis Software controls the family's DC power and electronic load modules installed in up to four N6705 mainframes — up to 16 modules simultaneously — from a single PC, adding enhanced data visualization and management.
