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 modules. Built on an advanced switching power supply design that fits within 1U of rack space, a single mainframe holds one to four DC power modules, and 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, economical DC power is all that is needed.

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.

Brand Heritage

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. Equipment bearing the Agilent name reflects this period of the brand's continuous corporate lineage.

Compare Other Models in This Series

The N6700 Modular Power System is a single 1U platform built around three 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 same modules also run in the N6705 DC Power Analyzer, a bench mainframe that adds front-panel scope view, arbitrary waveform generation, and data logging, allowing test correlation and program sharing between R&D and manufacturing.

The modules themselves fall into distinct series — basic DC power (N6730, N6740, and N6770 ranges), high-performance autoranging (N6750 series), precision (N6760 series), source/measure units (N6780 series), and application-specific (N6783A) — so a single mainframe can combine a high-power autoranging output with several economical basic outputs. 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.

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 to see its pre-owned availability and details.

The mainframes differ chiefly in total available output power — 400 W, 600 W, and 1200 W for the N6700B, N6701A, and N6702A respectively. Output sequencing can be synchronized across multiple units by wiring the rear-panel I/O ports together, a capability supported on the N6700B, N6701A, and N6702A. The N6702A 1200 W mainframe additionally senses the available AC line power at turn-on and automatically scales back output power to avoid overloading a standard AC outlet, limiting output to 600 W so a high-power mainframe can be plugged into any standard outlet.

Among the modules, the differences are output rating (from 18 W up to 500 W), voltage and current range, ripple and noise, and programming and measurement accuracy, along with which series each belongs to. The 300 W and 500 W autoranging and precision modules each occupy two of the four module slots. The comparison table below lays out these per-model ratings side by side so the right module can be matched to each output requirement.

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

Replaces: per the manufacturer, this model replaces 6621A, 6622A, 6623A, 6624A, 6625A, 6626A, 6627A, 6628A, 6629A.

Product Core & Specifications

N6776A DC Power Module — Detailed Specifications

Mainframe Key Characteristics (N6705 DC Power Analyzer)

DC Power Module Family — Key Performance Specifications

For the N6761A–N6766A precision modules and the N6781A/N6782A/N6784A SMU and N6783A application-specific modules, the values shown are for the highest output/measurement range; these modules have multiple ranges.

Important: DC power modules require an Agilent N6700-series mainframe (N6700B/N6701A/N6702A) or N6705 DC Power Analyzer (N6705A/N6705B) to operate; a module is not a standalone instrument, and it is ordered separately from the mainframe. At least one DC power module is required for the system to function. 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.

Important: Each module occupies one module slot, except the double-wide N6753A–N6756A high-performance autoranging and N6763A–N6766A precision modules, which each occupy two of the four mainframe slots.

Important: Installing a 500 W module in the N6700B 400 W mainframe may prevent that module from running at its full rated output power.

Important: The mainframe's total available output power is 600 W on the N6705. If the sum of the installed module power exceeds the mainframe's available output power, the power management feature allocates available power to the outputs where it is needed.

Important: Output current is derated 1% per °C above 40 °C ambient temperature.

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.

Important: Maximum series operation is 240 V; maximum rated parallel operation is 100 A per N6705. Front-panel binding posts are rated for 20 A per post; modules with outputs rated greater than 20 A (such as the N6753A) route their high-current wiring through the N6705 rear panel, for which the N6705B mainframe provides rear-panel access ports (for an N6705A mainframe, order N6705U-057 to replace the rear panel).

Important: Option 760 (Output Disconnect/Polarity Reversal Relays) limits the output current to 10 A maximum on Models N6742B and N6773A, and is not available on Models N6741B, N6751A, N6752A, N6761A, and N6762A. Option 761 provides output disconnect relays. Option 2UA (200 µA measurement range) is available only on Models N6761A and N6762A.

Important: Option LGA (large-size FPGA) must be ordered on the N6751A and N6752A modules; it is required to support output sequencing between multiple mainframes. Output sequencing synchronization across multiple mainframes is supported on the N6700B, N6701A, and N6702A mainframes; it is not supported on the discontinued N6700A mainframe.

Important: For model N6712A, 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. An AC mains rated at 100–180 VAC cannot supply enough current to power the N6702A mainframe at its full rated power; at that input, internal circuits limit the power available to modules to 600 W maximum.

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: If you will be rack mounting the N6700, you must order the rack mount kit (option 908 / N6709A); standard rack mount hardware, rails, or slides are not compatible with the N6700 because of its 1U size and airflow requirements.

Important: N6783A modules cannot be used in series with other N6783A modules or any other N67xx module.

Important: When sinking power, Model N6784A can operate at the maximum rated output power for only a limited amount of 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: 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. New modules N6753A and N6754A require mainframe firmware version C.02.00 or greater.

Important: Performance specifications for the N6780 Series 2-quadrant SMU modules (N6781A, N6782A) are not included here; see the N6780 Series Source/Measure Units (SMUs) for the N6700 Modular Power System Data Sheet, literature number 5990-5829EN. This page does not include a comprehensive list of all power module specifications; complete performance specifications and supplemental characteristics for all power modules are in the Agilent N6700 Modular Power System Family Specifications Guide, part number N6700-90001.

Recommended pairing: the Agilent 14585A Control and Analysis Software controls up to four N6705 mainframes — up to 16 power modules simultaneously — from a single PC, adding enhanced data visualization and management.
