I-TS-3872 / I-TS-3872-SiC DC Source/Sink
The I-TS-3872 is Gustav Klein's liquid-cooled, dual-channel DC source/sink from the standard line: the two channels can run individually, in series or in parallel, and selected options extend it for specific applications. A SiC (silicon carbide) version is planned, offering the same footprint at higher power output.Who Is the I-TS-3872 For?
Test engineers who need higher DC power (300-880 kW) in a compact, liquid-cooled footprint for battery, fuel cell and powertrain testing — including EV/EVSE testing and applications where two channels in series or parallel simplify the test bench — and who value a standardized product over a fully custom build.Available Models & Accessories
The I-TS-3872 is available in three standard liquid-cooled configurations from 300 kW to 880 kW at up to 1500 V and 1000 A, plus two planned SiC variants at 1200 V and 2000 A. Options add special input voltages, a function generator for superimposed AC signals, additional fieldbus interfaces, and cabinet finishing options. PDSB and PDU distribution accessories, and the Safety Master for parallel operation, are available separately.Liquid cooling keeps footprint down at high power
880 kW from a single dual-channel cabinet, where an air-cooled equivalent would need more enclosure volume.
Channel topology adapts to the test
The same two channels can be run individually, in series for higher voltage, or in parallel for higher current, without reconfiguring hardware.
SiC technology raises the power ceiling in the same footprint
The planned SiC variants add power output and efficiency while reusing the standard I-TS-3872 cabinet size.
Two units combine safely
Plug-and-play parallel operation of two identical I-TS-3872 systems is a built-in mode, not a custom integration project.
