Power supply series sets new standards for battery applications

The Rohde & Schwarz R&S NGL200, and the new R&S NGM200 series, provide the same excellent performance and specifications to supply extremely stable outputs with minimum residual ripple and noise. Devices that switch from a few µA in sleep mode to several A in active mode benefit from the particularly fast load recovery time of less than 30µs. The two-quadrant architecture offers both source and sink functions, to simulate the charging and discharging of batteries plus operate as an electronic load. The large capacitive touch screen and easy operating concept set new standards for power supplies.


Also, with the series, the company has introduced four new features: the FastLog function that captures spikes even in the µs range. Further measurement ranges that improve the read-back accuracy in the lower ranges. The battery simulation option that promotes the modelling of batteries to simulate real-life conditions, as well as the built-in digital voltmeter that measures voltage values at any point in circuits of the device under test.






For maximum read-back resolution and accuracy, the power supplies offer four current and two voltage measurement ranges, resulting in a read-back resolution of 10nA/5µV in the smallest range.


For any battery-driven equipment, simulating changes in battery output performance offers realistic power conditions at various stages of battery life. With the integrated battery model editor, users can produce their own battery models by determining battery characteristics such as the state of charge, open-circuit voltage and equivalent series resistance. Pre-defined data sets for the common battery types Lead, Lithium-Ion, Nickel-Cadmium, or Nickel-Metal hydride are included.
