Keysight DP5728A DC Power Supply

The DP5728A DC power supply offers a range of built-in features tailored for system integration, including various standard I/O interfaces that streamline and speed up test system setup. Its compact and secure design maximizes space efficiency in both lab and manufacturing environments, making it an excellent choice for industries such as aerospace and defense, automotive, communications, and component manufacturing.

Features and Specifications

• 80 Volts, 19 Amps, 1.52 kW.

• Single-phase 100 – 240 VAC universal input for 1.5 kW models.

• Small high-density 1U package.

• Intuitive front-panel operation.

• Built-in voltage and current measurements.

• Comprehensive protection from overvoltage and overcurrent.

• Standard LAN, USB, and GPIB interfaces.

• Easy-to-use Standard Commands for Programmable Instruments (SCPI) with IVI-COM drivers.

• Full compliance with the LXI Class C specification.

• Lockable controls against accidental power-supply parameter changes.

• Optional removable SD card for added security.

Arbitrary Generator for Variable Output

• Simulate real-world conditions.

• Characterize device performance.

• Conduct dynamic load testing.

Adjustable Slew Control for Precise Output Control

• Minimize voltage spikes.

• Improve load transient response.

• Optimize power delivery.

Programmable Internal Resistance

• Mimic series resistance with the output terminal of the power supply.

• Simulate as a source with a variable resistance, such as a battery.

Analog Programming and Monitoring

Voltage and current can be programmed from zero to full scale using either an analog voltage of 0 – 5 V / 0 – 10 V or a resistance of 0 – 5 kΩ / 0 – 10 kΩ. This capability also enables monitoring of voltage and current signals.

Flexible Configuration

For applications requiring higher power, the DP5700 Series delivers up to 3.4 kW per unit. Up to four units of the same rating 3.4 kW units can be connected in parallel for greater current, or two in series for greater voltage (see output terminal isolation information).

High-Power Automated Test Equipment (ATE) System

• Compact instrument ideal for ATE racking.

• More units per rack enable higher channel density and throughput.

• Stack directly above or below without obstructing airflow.

• Optional rack mounts available: DP5701A (1.5 kW) or N5740A (3.4 kW).

Keysight’s I/O Libraries Suite

The DP5700 ships with the Keysight I/O Libraries Suite, enabling fast and reliable connections between your PC and test instruments—regardless of the manufacturer. It ensures strong instrument control and integrates seamlessly with your preferred software development tools.

• Automatically detects instruments connected to your PC and configures the interfaces.

• Enables instrument communication for a variety of development environments (Mathworks MATLAB, Python, NI LabVIEW, Microsoft Visual Studio, and more)

DP5700 Series

The DP5700 Series DC power supplies are compact and secure, designed to maximize space efficiency in lab and production environments. It includes 40 single-output programmable models and provides stable output with built-in voltage and current measurements, with operating ranges up to 600 V / 150 A (on the 1.5 kW models) and 600 V / 340 A (on the 3.4 kW models). Flexible system scaling is possible by connecting up to four units in parallel to increase current or two in series to increase voltage. Validate complex power devices faster, in less space, with no compromise on performance.

DP5700A Series Q & A

1. How many models are available in the DP5700 Series?
   The lineup includes 68 programmable models with single outputs, featuring 1.5 kW units in a half-rack width or 3.4 kW and 5.2 kW units in a full-rack width—both maintaining a slim 1U height. These units deliver consistent power output and come equipped with integrated voltage and current measurement capabilities. The 1.5 kW models support up to 600 V / 150 A, while the 3.4 kW models handle up to 600 V / 340 A and the 5.2 kW models operate up to 600 V / 500 A.

2. Why should I upgrade from the Keysight N5700 / N8700 Series to the DP5700 Series?
   The DP5700 series of power supplies feature higher density with 1/2 half size of N5700 / N8700 instruments. They also include an arbitrary generator, adjustable slew control and programmable internal resistance.

3. What is provided with the three years of KeysightCare support?
   KeysightCare offers dedicated access to technical specialists and a 24/7 online knowledge base. You’ll benefit from tailored, proactive, and prioritized support. Use the Knowledge Center to find solutions, track service requests, and connect with Keysight experts. However, upgrading to KeysightCare Enhanced adds long-term assurance—covering up to five years—and includes your preferred calibration service with expedited turnaround, helping you avoid unexpected costs.
