Alimentatore elettrico da tavolo R&S®NGA100

DCregolatoa corrente costante

Overview R&S®NGA100 DC power supplies are linear, compact and easy to use. All models offer excellent readback accuracy with a low-current range for demanding measurements. Data logging, arbitrary waveforms, built-in statistics and remote sensing features make the instruments suitable for bench applications such as R&D, IoT low-power design, manufacturing, education and general-purpose use. Equipped with USB and Ethernet remote interfaces, the instruments are suitable for automated tests. The channel fusion feature extends voltage and current range (up to 200 V in serial mode or up to 12 A in parallel mode). Advanced protection functions protect connected devices and the power supplies.

Features & benefits

• Linear design — Linear output stages for minimum residual ripple and noise, supplying extremely stable output voltage and current for sensitive circuits.
• High readback accuracy — Outstanding programming and readback accuracy; low-current measurement range with resolution 1 µA for currents ≤ 200 mA; integrated statistics (min/max values for power, voltage, current).
• FlexPower — Delivers maximum power at various operating points; shows all possible voltage/current combinations in FlexPower curves.
• Channel Fusion — Two output channels (on NGA102/NGA142) can be fused in series or parallel to double voltage or current capability (serial internal, parallel requires external wiring).
• Easy-to-use configurator — Online configurator provides full price transparency and fast order processing through distribution partners.
