R&S® NGP804

The R&S® NGP800 DC power supply series, comprising five models with 400 W or 800 W, provides maximum power at a variety of operating points. The two or four 200 W outputs can each supply up to 64 V or up to 20 A. Electrically equivalent and galvanically isolated outputs can be wired in series or parallel for up to 250 V or 80 A.

Synchronizing your outputs, performing waveform tests and logging data for in-depth analysis – all this becomes easy with the R&S® NGP804 power supply.

An intuitive operating concept and a large touchscreen allow you to enter values much faster and to display statistics in realtime.

All R&S® NGP804 power supplies include remote sense terminals, USB and a LAN interface. A user-installable GPIB interface, a digital trigger I/O, an analog input and a wireless LAN interface are optional, making these instruments great on the bench or in an automated test system.

Special features

5" high-resolution touch display

The large high-resolution touch display makes operation easy. Quickly navigate through the menus to access all functions and settings. Enter values much faster using the virtual keyboard instead of turning the knob.

FlexPower

Get the maximum power at various operating points. Unlike with single range power supplies, you can generate variable voltage and current combinations within the overall power limit of 200 W per channel.

Four power supplies in a single instrument

Save costs and space on your bench or in your rack by powering up to four DUTs with a single instrument. Each output is completely independent and floating. All outputs can operate in constant voltage (CV) or constant current (CC) mode with automatic crossover and mode indication. A separate output button allows you to synchronously switch all channels on or off. This is crucial for circuitries that can be damaged if one voltage rail is present without the other. The individual channel buttons let you select the channels you want to operate.

Parallel and serial operation

In case your application requires more voltage or current, connect the outputs in series or parallel and get up to 250 V (NGP824) or 80 A (NGP804) – giving you the flexibility you always asked for. Using the tracking function, voltage and current are adjusted on all selected channels simultaneously.

Ramp function (EasyRamp)

To control inrush currents, some test setups require the continuous rise of the supply voltage instead of a rapid jump. Increase the output voltage continuously within a timeframe of 10 ms to 60 s with the EasyRamp function.

Arbitrary function (QuickArb)

Emulate the normal behaviors of your power subsystems early in the design process and simulate power problems for DUT design verification. The QuickArb function lets you generate voltages that vary over time and current sequences of output changes with dwell times down to 1 ms. Load up to eight subgroup files into one sequence to create complex patterns.

Data logging

Logging data is key to long-term monitoring, reviewing test setups and repeating test conditions when analyzing power behaviors or optimizing power consumption. The R&S® NGP800 power supplies simultaneously log voltage and current measurements over time on all outputs. You can easily export the timestamped data as a .CSV file for reports and documentation.
