Rohde & Schwarz has launched a four channel power supply for test and measurement applications requiring up to four independent DC outputs with a 5in high resolution touch screen for detailed statistics.
The five R&S NGP800 models meet the needs of users seeking minimum device footprint for two or four independent power supplies with voltages up to 250V, currents up to 80A and power up to 800W. Each channel supplies up to 200 W with a maximum of 20 A or 64 V, also covering 48 V automotive and industrial applications.
Channels can be operated fully independently or synchronized; the electrically equivalent and galvanically isolated outputs can be wired in series for outputs up to 250 V or in parallel for up to 80 A. The tracking function makes it possible for users to adjust voltage and current simultaneously on selected channels, with programmable output delays used to meet specific power-up sequences. The supplied voltage can be ramped up to the required level in any period from 10 ms to a minute. All outputs operate in either constant voltage mode or constant current mode.
To meet the requirement of both developers and quality assurance teams in particular, it is possible to set up changes in voltage and current level over time using the QuickArb function. This way, users can simulate instable power supplies with the R&S NGP800. Using Remote Sensing, users can regulate the voltage directly at the input terminals of the powered device itself, instead of the power supply’s output terminals, so that exactly the required voltage is supplied.
Moreover, the R&S NGP800 includes functions for logging voltage, current and power values over time for all outputs. Data logs can easily be exported as .CSV files for in-depth analysis or documentation needs. The settings for all channels and functions can also be stored and recalled at the touch of a button, and even exported as a file to other R&S NGP800 to duplicate the power setup.
