MI-TS-3871 Multi-Channel DC Source/Sink

Gustav Klein

Key Features

  • 2 or 4 independently usable DC channels in one system
  • Channels are linked via an internal DC bus, so energy delivered by one channel can be recycled directly to another through the DC converters, with the AC grid supplying or absorbing only the net difference
  • 6 configurable voltage classes from 300 V to 1500 V (5-1500 V adjustable output), nine power levels from 60 kW to 650 kW per channel
  • Modbus TCP, CAN-bus (100 Hz, dbc file) and VNC over Ethernet as standard
  • Optional Profibus DP, Profinet, EtherCAT or LabVIEW interfaces
  • Optional per-channel selective insulation monitoring (2 or 4 channel)

MI-TS-3871 Multi-Channel DC Source/Sink

The MI-TS-3871 is Gustav Klein's multi-channel DC source/sink from the customized line: two or four independently usable DC outputs in one system, individually configured from a wide range of options rather than ordered off a fixed catalog. Orders are processed by GK's electrical and mechanical engineering departments, so delivery time and cost depend on the specific configuration.

Who Is the MI-TS-3871 For?

Test engineers who need multiple independent DC outputs — for testing several devices or channels in parallel — in a single system, where the standard line's fixed single-channel or dual-channel designs don't cover the required channel count, voltage class, or power level.

Available Models & Accessories

Each MI-TS-3871 system combines a Basic DC-Source module (power rating) with a separate DC-Converter module (channel count and current rating). The Basic DC-Source is available in nine power levels from 60 kW to 650 kW; the DC voltage class matched to each power level is shown below (6 classes, 300-1500 V overall). The DC-Converter is chosen independently for 2 or 4 channels and 200-1200 A; two examples are shown below, the full range is configured to order. Options add insulation monitoring (including selective per-channel monitoring), increased insulation resistance, and additional fieldbus interfaces. PDSB and PDU distribution accessories, and the Safety Master for parallel operation, are available separately.

Multi-channel testing without separate cabinets

2 or 4 independently usable DC outputs in one system, useful for testing multiple devices or channels in parallel.

Voltage and power are chosen, not fixed

Six DC voltage classes from 300 V to 1500 V and power from 60 kW to 650 kW per channel let the configuration match the test object instead of the other way round.

Selective insulation monitoring isolates faults per channel

A channel with an insulation fault switches off on its own, without stopping the other channels; this option requires special software and a PDSB.

Energy recycled directly between channels via the internal DC bus

One channel can source while another sinks, with energy flowing straight between them through the DC converters instead of round-tripping through the AC grid, which then only supplies or absorbs the net difference — useful with a limited grid connection or when managing AC peak loads, and the basis for using a 2-channel MI-TS-3871 as a HiL test bench for DC/DC converters.
