# Agilent N6774A 35 V, 8.5 A, 300 W DC Power Module (Pre-Owned) # Agilent N6774A 35 V, 8.5 A, 300 W DC Power Module (Pre-Owned) ## Key Features At A Glance - 1U-high mainframe holds one to four DC power modules — up to four outputs per rack unit; mix and match from over 30 DC power modules to build a 1- to 4-channel system - GPIB, USB 2.0, and 10/100 Base-T LAN interfaces standard, with a built-in web server for monitor, control, and setup from any standard web browser; fully compliant to the LXI Class C specification - SCPI programming with VXIplug&play and IVI-COM drivers for ATE integration; command processing time of ≤1 ms - Built-in voltage and current measurement standard on every module; 4-wire remote sensing on each output improves voltage measurement accuracy - Each module protected against over-voltage, over-current, and over-temperature, with coupled-output faults detected within 10 µs; each output fully isolated and floating from ground and from the other outputs - Module output ratings span 18 W to 500 W across the family, with output voltages from 0–5 V up to 0–150 V - Optional Output Disconnect (option 761) and Output Disconnect/Polarity Reversal (option 760) relays built into modules - Optional High-Speed Test Extensions add arb-waveform and digitizer-style capture; installed in the N6705 DC Power Analyzer mainframe, modules add front-panel scope view, arbitrary waveform generation, and data logging 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. 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. 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. The precision modules in the family are suited to semiconductor and passive device testing, while high-speed measurement supports design validation of battery-powered digital devices where understanding current drain and DUT power management is important. The same module platform extends to the bench in the N6705 DC Power Analyzer, a modular instrument that sources and measures DC voltage and current into a device under test. It combines one to four DC power supplies 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, since all sourcing and measuring functions are available directly from the front panel. Engineers use it to view turn-on and turn-off sequences, measure and display voltage and current versus time to visualize power into the DUT, control DC bias ramp-up and ramp-down rates, generate transients and disturbances, and log data over seconds, minutes, hours, or days; a common task is inrush current measurement, triggering the oscilloscope on the DC output's on/off key in single-shot mode to capture the current flowing into the DUT as the output turns on. 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 originally branded Agilent is part of that 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 modules themselves fall into distinct series — basic DC power (N6730 50 W, N6740 100 W, N6770 300 W), high-performance autoranging (N6750), precision (N6760), source/measure units (N6780), and application-specific (N6783A) — so a single mainframe can combine a high-power autoranging output with several economical basic outputs. The same modules also run in the N6705 DC Power Analyzer used at the bench, allowing test correlation and program sharing between R&D and manufacturing; a 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. 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 configuration 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 — and only the N6702A offers the automatic AC-line power scaling that lets a 1200 W frame run from a standard outlet. Cross-mainframe output sequencing is supported on the N6700B, N6701A, and N6702A. The N6705 DC Power Analyzer mainframe is a four-slot bench frame providing 600 W of total available power; the N6715B is the same system ordered build-to-order with one to four modules pre-installed. 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 high-performance autoranging and precision modules add lower noise and faster voltage changes; the precision series further provides dual programming and measurement ranges with 16-bit programming and 18-bit measurement precision, while the N6780 source/measure units add multi-quadrant operation and highly accurate measurements down to nanoamperes. The comparison table below lays out these per-model ratings side by side so the right module can be matched to each output requirement.

The basic capabilities of a power module depend not only on its own hardware but also on the hardware and firmware of the mainframe in which it is installed, and at least one DC power module is required for the system to function. > **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:** Each module occupies one module slot, except the N6753A–N6756A and N6763A–N6766A double-wide modules, which each occupy two of the four mainframe slots. The N6753A and N6754A 300 W high-performance autoranging modules each occupy two module slots. > **Important:** The mainframe's total available output power is 600 W. 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:** For modules with outputs rated greater than 20 A (such as the N6753A), high-current wires must be routed through the N6705's rear panel; the N6705B mainframe provides rear-panel access ports for this (for an N6705A mainframe, order N6705U-057 to replace the rear panel). > **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. > **Important:** Output current is derated 1% per °C above 40 °C ambient temperature. > **Important:** For model N6702A (and N6712A system), the maximum output power is limited to 600 W at 100–120 VAC; an AC mains rated 100–180 VAC cannot supply enough current to power the mainframe at full rated power and internal circuits limit module power to 600 W maximum. To achieve full output power of 1200 W you must use option 929 and operate at 200–240 VAC. > **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 empty slots must be filled for proper operation. > **Important:** Rack mounting requires 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:** 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, N6762A, and N6781A–N6784A. > **Important:** 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. > **Important:** Output sequencing synchronization across multiple mainframes is supported on N6700B, N6701A, and N6702A mainframes; it is not supported on the discontinued N6700A mainframe. > **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), requiring a protect clear to resume operation. > **Important:** New modules N6753A and N6754A require mainframe firmware version C.02.00 or greater (available at www.agilent.com/find/N6700firmware). > **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. > **Important:** Performance specifications for the N6780 Series 2-quadrant SMU modules (N6781A, N6782A) are not included in this datasheet; see the N6780 Series Source/Measure Units (SMUs) for the N6700 Modular Power System Data Sheet, literature number 5990-5829EN. This data sheet also 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. > **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. > 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. These DC power modules install in the Agilent N6700B through N6705B mainframes covered in this series, including the N6705 DC Power Analyzer mainframe for front-panel scope view, arbitrary waveform generation, and data logging. ## About this Pre-Owned unit This pre-owned unit is inspected and functionally verified in-house before it ships and is backed by our pre-owned warranty.
