Cabinet power supply I-TS-3870-ol

DCsingle-outputthree-phase

Product overview
I-TS-3870-ol is a single-channel, high-dynamics bidirectional DC source/sink for testing and simulating batteries, fuel cells and powertrains. One output up to 1500 V and 1200 A. Single-operation power up to 650 kW; parallel operation up to 2.6 MW. Actual voltage, current and power depend on configuration.

Overload capability
The overload-capable variant provides short-term DC output overload: up to +50% rated output for a maximum of 60 s. Regeneration time at ≤ nominal load equals 5 × overload time. DC converter voltage and current technical limits remain unchanged.
