Cabinet power supply I-TS-3870

DCsingle-outputIP54

Overview
The I-TS-3870 is a single-channel, high-dynamic bidirectional DC source/sink system for testing and simulation of batteries, fuel cells and e-powertrains. Single output up to 1500 V and up to 1200 A; maximum power in single operation up to 650 kW and up to 2.6 MW in parallel operation. Continuous seamless transition between source and sink modes makes it suitable for automotive, hydrogen, laboratory and industrial power-electronics testing.
