Multi-Channel System – overload
MI-TS-3871-ol: Multi-channel system for energy-saving tests and simulations. Two or four outputs, up to 1500 V or 1200 A per output (without galvanic isolation between the DC outputs // maximum values for voltage, current and number of output channels depending on the specific configuration).
Our high-performance test system MI-TS (Multichannel Infeed test system – overload) is a multi-channel, highly dynamic, bidirectional DC power supply with continuous and seamless transition from source to sink mode. Thanks to its multi-channel capability and outstanding performance, the MI-TS is the ideal test system for a wide range of applications in the automotive, hydrogen and laboratory sectors.
The MI-TS-3871 overload-capable version of our multichannel infeed test system enables a short-term overload at the DC output and also offers the option of parallelizing the output channels. This allows certain operating points outside the nominal range to be approached and thus requirements in the test sequence to be fulfilled by the MI-TS. The technical data of the DC converter in terms of output voltage and output current remain unchanged. However, a nominal output load up to 50 % higher is available for a maximum of 60 s.
The subsequent regeneration time (≤ nominal load) is 5 times the overload time.
Standard features
- The MI-TS-3871-ol (overload) already impresses in the
standard system configuration with its extensive
equipment and is therefore ready for immediate use by customers from all over the world. The following is a small excerpt::

Options (extract)
- Security level
Increase to performance level e as a special option - Battery emulation version (increased output capacity)
Hardware and software adaptation for special applications
to improve voltage stability for battery emulation - Protective diode at the DC output Switchable diode to protect the device under test in sink-only mode
- Insulation monitoring Protective device for monitoring the galvanic isolation of the DC output
- Interfaces Large selection of various optional interfaces such as CAN high-speed (1 kHz), SCPI, EtherCAT, Profi bus, Profi net, analog, LabVIEW, Matlab/Simulink
- DC output contactors with higher performance
DC output contactors with increased current capability are optionally available to increase the service life - Door contact switch, door locking device, special locking cylinder
Operator safety is our top priority, therefore additional safety equipment is available for our customers
- Schaltschränke in Sonderausführungen Rittal Schaltschränke, Sondersockel, Schränke auf Rollen,
Sonderlackierungen, Aderendkennzeichnung. Das I-TS kann
an die verschiedensten Kundenwünsche und örtlichen
Gegebenheiten angepasst werden - NA protection with grid analysis measuring device for
generation systems (VDE-AR-N 4105, VDE-AR-N 4110)
Due to grid operator guidelines, NA protection may be required to monitor the grid quality for the MI-TS - Water cooling including increase of the degree of protection to IP54
Water cooling of the control cabinets is available to minimize waste heat to the room and noise reduction. This also increases the degree of protection of the MI-TS
Typical applications
- Battery tests (charge and discharge tests of batteries)
- Battery simulation / battery emulation
- Load for fuel cells
- Test power supply for contactors, fuses and circuit breakers
- Test of DC motors (drive train)
- Testing of charging columns (comemso)
- Power supply to trains for maintenance purposes at the ICE (German high speed train) plants
