DC source/sink
Flex-Channel System Custom:
I-TS-3872 / I-TS-3872-SiC Standard: State-of-the-art, liquid-cooled DC source/sink. Depending on your requirements, the system can be used in various operating modes. Selected options provide additional support for your application.

Our high-performance test system I-TS (Infeed test system) is a highly dynamic, bidirectional DC power supply with continuous and uninterrupted transition from source to sink operation. Thanks to the 3-level technology, it offers an adjustable voltagerange of 10–1,500 V with a grounded neutral point. However, the DC channels can also be operated individually or in parallel. The outstanding performance is the basis for a wide range ofapplications in the automotive, hydrogen and laboratory sectors.
