The R&S®NGA100 DC power supplies are linear, compact and easy to use in diverse scenarios. All models have 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 ideal for various bench applications, such as:
- R&D;
- Creating IoT low power designs
- Manufacturing
- Education
- General purpose use cases
Equipped with a number of different remote interfaces, including USB and Ethernet, R&S®NGA100 DC power supplies are also great for automated tests. The channel fusion feature extends voltage and current range. Get up to 200 V with the R&S®NGA142 in serial mode and up to 12 A with the R&S®NGA102 in parallel mode. Advanced protection functions keep devices connected and power supplies safe.
Choose the DC power supply for your use case by selecting the base unit and necessary options in our online configurator. This makes the procedure easy and fully price transparent for fast processing of your order request by our authorized distribution partners. Click "configure and quote" to start your configuration.
Confidently power sensitive circuits
Advanced electronic circuitry is often complex and sensitive
to supply line interference. The linear design of the output stages allows the R&S®NGA100 power supplies to operate with minimum residual ripple and noise. Supplying extremely stable output voltage and current is crucial when developing sensitive components.

With integrated statistics
R&S®NGA100 power supplies have outstanding programming and readback accuracy to precisely measure and replicate actual device power consumption, even at low voltage and current levels. IoT devices can have multiple sleep modes where current consumption is very low. To accurately determine these operating states, R&S®NGA100 power supplies have a low-current measurement range. Currents below 200 mA are measured with a resolution of 1 μA and an accuracy of ±(0.15 % + 25 μA). In addition, integrated statistics show the min. and max. values for power, voltage and current. These built-in measurements reduce the need for external multimeters and simplify the setup.
Low-current measurement range
For output currents ≤ 200 mA the measurement resolution is 1 µA
Get the maximum power at various operating points
The R&S®NGA100 series operates with maximum power at various operating points and covers far more applications than single range power supplies. All possible voltage and current combinations are shown in the corresponding FlexPower curves.

Double the voltage or current capability of your power supply
The two output channels of the R&S®NGA102 and R&S®NGA142 operate in series or parallel for higher voltage or current. After activating serial or parallel channel fusion, the device will start to act like a one-channel power supply with double voltage or current capability.
In serial mode the outputs are connected internally, while the parallel mode requires external wiring.
The function enables even more applications to be covered by a single instrument.
