Description
Most bench supplies top out at a few tens of volts. The Rohde & Schwarz NGA141 supply reaches 100 V on its single output, at up to 2 A and 40 W. Lost in HCM lists it for rental and sale.
A wide voltage range at modest power
So this model trades current for voltage. The channel gives 40 W at most, so the available current falls as you raise the voltage. At 100 V, then, you can draw about 0.4 A, while the full 2 A is reachable at 20 V or below.
A quick example shows the limit. Take a 48 V module that draws 1 A: it needs 48 W, so it exceeds this supply. However, a 48 V sensor that draws 0.5 A needs 24 W, which fits.
Where a 100 V single channel helps
- Industrial sensors and small modules with a higher supply voltage.
- Component checks that need a wide voltage sweep at low current.
- Bias and stimulus duties on a development bench.
In these jobs the power demand is small, but the voltage range matters. In contrast, a low-voltage, high-current load belongs on a different model.
Set up with care
Also, higher voltage deserves a careful check. First, define the voltage range, the current limit and the pass criteria. Then verify polarity and connections while the output is disabled. Use leads and fixtures that suit the voltage, and set the protection levels before you enable the output.
Lost in HCM’s listing says the NGA100 series uses linear outputs and offers remote sensing and data logging. Even so, ask for the interfaces and options you need, because they vary by configuration.

NGA141 questions from the bench
How much current can I draw at 100 V?
About 0.4 A, because the channel stops at 40 W. The 2 A maximum applies only at 20 V or below.
Will a 48 V load that draws 1 A work?
No. That load needs 48 W, which is above the 40 W limit of the channel.
What is the manufacturer order number?
The manufacturer lists 5601.8002.03 for the NGA141.
