Keysight DP5799AH DC Power Supply New

The removable SD card option deserves a specific call-out. Test equipment that moves between confidential spaces — DoD facilities, AS9100 production lines, classified R&D labs — has historically required either purpose-built secure instruments or formal sanitization procedures for general-purpose hardware. The DP5700 Series solves this with a removable SD memory that supports equipment sanitization and detailed record-keeping of cleaning processes, including the methods and materials used, to maintain a clear audit trail and ensure accountability. For customers in regulated environments, this single feature changes which instrument is procurable.

DC Power Ratings — Verbatim by Power Class:

Selecting the right model starts with the DUT's power profile. Voltage range determines which model family fits the application — 0–30 V general electronics, 0–60 V telecom and automotive ECUs, 0–100 V+ industrial and motor controllers, and 0–600 V for high-voltage analog, battery-stack simulation, and traction inverter test. Current capability must cover both steady-state draw and inrush; at the 500 A end of the DP5700 range, the supplies are sized for high-current battery emulation, motor controller bus simulation, and production burn-in stations.

Scalability — Multiple Units in Parallel and Series:

• For applications requiring higher power, the DP5700 Series delivers up to 5 kW per unit.
• To increase output current, up to twelve identical units (3.4 kW and 5 kW models) can be connected in parallel.
• Two units can be connected in series to increase output voltage (see output terminal isolation information).

Twelve 5 kW units in parallel yields 60 kW of single-output programmable DC power — the operating point of large motor controller benches, EV traction-inverter test stations, and high-current battery-pack simulation. The series-connection capability adds another path: pairing two 600 V units in series produces a 1,200 V test source for high-voltage device characterization. The output terminal isolation specification governs both modes: for 10 ~ 100 VDC rated output, no point may be at a greater potential of ±200 VDC from ground; for 150 ~ 600 VDC rated output, no point may be at a greater potential of ±600 VDC from ground.

Protection Architecture:

• Overtemperature Protection (OTP) — shuts down the output when a fault occurs.
• Overcurrent Protection (OCP) — shuts down the output when a fault occurs.
• Overvoltage Protection (OVP) — shuts down the output when a fault occurs.
• Undervoltage Protection (UVP) — prevents voltage adjustment below a set limit. Combined, UVP and OVP create a protection window for sensitive load circuitry.

System Integration & Programmability:

• Computer Interface (standard): 10/100 Base-T Ethernet (sockets, VXI-11 protocol, web user interface), USB 2.0 (USB-TMC488 protocol), GPIB (IEEE 488).
• LXI version: 1.5 LXI Device Specification 2023.
• LXI extended functions: LXI IPv4, LXI HiSLIP, LXI VXI VXI-11 Discovery and Identification.
• Programming language: SCPI-1999, IEEE 488.2 compliant.
• Drivers: IVI.NET drivers to simplify system development.
• Command response time: < 10 ms.
• Savable states: 10.
• Analog programming input range: 0 to 5 V or 0 to 10 V (selectable).
• Analog programming accuracy: Specified instrument accuracy ±0.2% of rating.
• Analog programming input impedance: 150 kΩ (referenced to ground).

For automated test integration, the question to ask before recommending any supply is whether the test infrastructure uses GPIB, USB, or LAN. The DP5700 supports all three as standard. For new automated test builds where LXI hardware triggering matters — sequencing the supply with an oscilloscope acquisition, a relay enable, or an electronic load step — the series' LXI Class C compliance and HiSLIP support deliver the synchronization layer.

Advanced Sourcing Capabilities:

• Programmable Internal Resistance — simulates a voltage source with variable series resistance, enabling realistic source impedance emulation for testing devices under more representative operating conditions (e.g., battery behavior).
• Built-in Arbitrary Generator — creates complex voltage or current waveforms that replicate real-world operating environments. Can be synchronized with other test instruments to support coordinated testing setups.
• Adjustable Slew Control — manages the rate of voltage change during operation, minimizing voltage overshoot and spikes for sensitive devices requiring carefully managed power ramp-up or ramp-down behavior.

AC Input — Verbatim by Model Group:

Note: Due to the number of different line cords and terminations around the world, the DP5700 power supplies do not come with line cords or terminations. Users will need to supply their own depending on the local laws and codes of the country/region where the power supply will be used.

In summary, the Keysight DP5700 Series is a 68-model family of single-output programmable DC power supplies engineered for high-density rack-mount integration in automated test, R&D, EV-battery, and motor-controller applications. The series spans 1.5 kW, 3.4 kW, and 5 kW power classes — all in 1U chassis — with voltage coverage from 10 V to 600 V and current capability to 500 A, plus standard LAN, USB, GPIB, and LXI Class C connectivity. Programmable internal resistance, a built-in arbitrary generator, adjustable slew control, and removable-SD-card security make it the right system supply for production test, classified environments, and automated test integration where rack density and software control are non-negotiable.

What is the Keysight DP5700 Series used for?

The DP5700 Series is used in automated test systems, production-test lines, EV and battery-pack characterization, motor-controller test, and any laboratory or production environment that requires high-density programmable DC power with software control. It delivers up to 5 kW per 1U unit and scales to 60 kW via twelve-unit parallel operation, addressing applications from precision low-voltage device characterization through 600 V high-voltage stack simulation.

Production-test integrators choose this series because it consolidates voltage, current, measurement, and protection into a single 1U slot — freeing rack space for other instruments. R&D engineers choose it for the programmable internal resistance and arbitrary generator, which simulate real-world source impedance and dynamic load conditions during device characterization.

Does the DP5700 work with LabVIEW, Python, and MATLAB?

Yes. The DP5700 Series supports SCPI-1999 and IEEE 488.2 compliant commands and ships with IVI.NET drivers, making it directly compatible with LabVIEW, Python, MATLAB, TestStand, and any test executive that supports standard test-and-measurement instrument drivers. Standard LAN, USB 2.0 (USB-TMC488 protocol), and GPIB (IEEE 488) interfaces are included on every model — no interface option to specify at order.

Full LXI Class C compliance — including LXI HiSLIP and LXI VXI VXI-11 Discovery and Identification per the 1.5 LXI Device Specification 2023 — adds hardware-triggered synchronization across networked instruments, which is the standard requirement for new automated test builds in 2026.

How dense is the DP5700 compared to a conventional rack supply?

The DP5700 delivers up to 5 kW in a single 1U full-rack chassis — substantially denser than conventional 2U or 3U system supplies at the same power level. The 1.5 kW models occupy only a 1U half-rack slot, which means two units fit side-by-side in a single 1U rack space for 3 kW total, with front and rear air vents that allow direct vertical stacking without airflow obstruction.

Combined with up to twelve-unit parallel scaling on 3.4 kW and 5 kW models, a single rack can deliver 60 kW of programmable DC power — a footprint advantage that materially affects test-cell capacity planning.

Factual Grounding — Hard Numbers Buyers Quote

The DP5700 Series operates over 0 °C to 40 °C, 20–90% relative humidity (non-condensing), at altitudes up to 3,000 m with derating. Command response time is under 10 ms, recovery time is 1 ms on 1.5 kW and 3.4 kW models (load change 10%–90% / 90%–10%), and the analog programming input has 150 kΩ input impedance with ±0.2% of rating accuracy.

For high-power production-test environments, audible noise matters: 1.5 kW models measure LpA 59.2 dB at the operator position at max fan speed and LpA 47.7 dB at idle; 3.4 kW models measure LpA 58.3 dB and LpA 50.4 dB respectively. These are below the OSHA 85 dB action level — relevant for 8-hour test-floor operator exposure compliance.

Standards & Compliance Alignment

The DP5700 Series complies with the European EMC Directive, the European Low Voltage Directive (CE-marking), US and Canadian safety regulations, Australian standards (C-Tick mark), and Canadian ICES-001 for ISM devices. The programming layer aligns with the LXI Consortium's 1.5 LXI Device Specification 2023, the SCPI Consortium's SCPI-1999, and IEEE 488.2 — the three standards that define interoperable test-and-measurement automation.

Keysight's instrument heritage traces to Hewlett-Packard's HP 6000 series, HP 721x, and HP E36xx lines — the lineage that established the modern programmable DC power supply category. Customers integrating into existing Keysight-based test architectures retain interface, command-set, and software-stack compatibility throughout the DP5700 family.

How the DP5700 Compares to a Standard Industry Baseline

• Density: 5 kW in 1U full-rack vs. a typical 5 kW supply in 2U or 3U — recovers 1–2U per channel in a production rack.
• Programmability: Standard LAN + USB + GPIB on every model vs. industry-typical "USB standard, GPIB optional" — no interface upgrade SKU to manage at order.
• Scalability: Up to 12 units in parallel (3.4 kW and 5 kW models) for up to 60 kW vs. typical 2–4 unit parallel limits on competing system supplies.
• Security: Removable SD card option (DP5705A) standard across the line — most competing system supplies offer this only on dedicated secure-variant SKUs at premium pricing.
• Sourcing capability: Programmable internal resistance + built-in arbitrary generator + adjustable slew control — features typically requiring an external SMU or arbitrary source on competing supplies.

Buyer Decision Framework — The Three Questions

• Voltage: The DP5700 covers 0–10 V through 0–600 V across 68 models — confirm the maximum, not the nominal, voltage the DUT requires, including any headroom for transient overshoot.
• Current (and inrush): Up to 500 A on 5 kW models. Confirm steady-state draw and startup inrush; capacitor charging on a DUT can pull 3–5× steady-state for tens to hundreds of milliseconds. Voltage × Current = Watts; size to peak, not average.
• Programmability & interface: Standard LAN, USB, GPIB, LXI Class C on every DP5700 model. Confirm the test-system software stack (LabVIEW / Python / MATLAB / TestStand) and existing infrastructure interface — then specify the DP5700 model whose voltage and current match the DUT envelope.
