I-TS-3840 DC Source/Sink
The I-TS-3840 is a single-channel, bidirectional DC source/sink from Gustav Klein's standard product line: a fixed design with a defined set of factory options, so orders require no engineering effort and lead time depends only on material availability and production capacity. It sources and sinks DC power for battery, fuel cell and powertrain testing, and can be paralleled for higher power.Who Is the I-TS-3840 For?
Test engineers who need a standardized, off-the-shelf bidirectional DC source/sink for repeatable battery, fuel cell and powertrain test benches — end-of-line testing, long-term cycling (e.g. WLTP-based), development-stage testing, and type testing — where a fixed configuration is acceptable and short lead time matters more than a fully custom design.Available Models & Accessories
The I-TS-3840 is available in two standard configurations, 260 kW and 400 kW, at 1500 V DC and up to 800 A. A fixed set of options — insulation monitoring, parallel control, stop/emergency-stop buttons in the cabinet door, and analogue I/O interfaces — can be added without additional engineering. PDSB and PDU distribution accessories, and the Safety Master for parallel operation, are available separately.Fixed configuration keeps lead times short
No engineering step between order and production; delivery depends only on material availability and factory capacity.
Parallel operation scales power beyond a single cabinet
2 systems in flexible or 4 in fixed parallel connection, extending a 400 kW unit well into the megawatt range.
Built for both roles in one cabinet
The same channel sources and sinks, with a display-switchable battery tester/emulator mode, so one system covers charge and discharge testing.
IP54 as a drop-in upgrade
The same electrical design is available in a water-cooled IP54 enclosure, without moving to a different product line.
