I-TS-3873 DC Source/Sink
The I-TS-3873 is Gustav Klein's project-specific solution for megawatt-range DC source/sink testing: a customizable high-power system, up to 5 MW in parallel operation, for battery container testing, MCS (megawatt charging), large commercial vehicles and electrolysers. It is not sold from a price list — each system is engineered and quoted per project, with GK's development department involved.Who Is the I-TS-3873 For?
Organizations testing at megawatt scale — battery container discharge testing, MCS (megawatt charging) validation, large commercial vehicle powertrain testing, or electrolyser load testing — where power or configuration requirements exceed what the standard or customized I-TS/MI-TS lines can deliver, and a project-specific engineered solution is the right starting point.Available Models & Accessories
I-TS-3873 configurations range from 600 kW to 2400 kW per unit, with 1, 2 or 4 channels and up to 5 MW in parallel operation; because it is a project-specific solution, dimensions and exact ratings are determined per project rather than listed as fixed models. Options include special input voltages, insulation monitoring, parallel control, and battery tester/simulator switching. PDSB and PDU distribution accessories, and the Safety Master for parallel operation, are available separately.Purpose-built for megawatt testing
Discharge testing of entire battery containers, MCS (megawatt charging) validation, and electrolyser load testing sit above what a catalog DC source/sink can cover.
Power scales through channels and parallel operation
1, 2 or 4 channels per unit, and up to 5 MW combined, so the system is sized to the test object rather than assembled from multiple smaller units.
GK's development department is part of the order, not an afterthought
Because this line isn't ordered from a price list, engineering and feasibility are built into the process from the start.
Covers heavy-duty use cases beyond standard EV testing
Large commercial vehicles and MCS charging are explicitly named applications, alongside battery, fuel cell and powertrain testing.
