Cabinet power supply I-TS-3872

DCvariable-outputthree-phase

Overview
I-TS-3872: State-of-the-art, liquid-cooled DC source / sink. Depending on requirements, the system can be used in single, serial or parallel mode. Voltages of up to 1500 V are possible in serial mode. The I-TS high-performance test system is a high-dynamic, bidirectional DC power supply with continuous and seamless transition from source to sink operation. Thanks to the 3-level technology, it offers an adjustable voltage range of 10 – 1500 V with a center point. The DC channels can be operated individually or in parallel. Outstanding performance for applications in automotive, hydrogen and laboratory sectors.
