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 and 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 version of our multichannel Infeed test system enables a short-term overload at the DC output and also offers the option of parallel output channels. This means that
certain operating points outside the nominal range can be approached and thus requirements in the test sequence can 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 M-TS-3871-ol (overload) impresses even 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:
General information - Input voltage 380 / 400 V, 50 / 60 Hz
- Sense connections for voltage measurement / regulation
- DC current and voltage measurement with 0.1 % full scale accuracy
- Battery tester version
- Protection class IP20
- Noise-reduced design (vibration metals, fan control)
- Air cooling
- Parallel operation of the output channels to increase the current
Safety features
- Lockable main switch as load-break switch
- Safety control for Performance Level d in accordance with EN 60204-1 / ISO 13849-1
- Stop switch in cabinet door
- Voltmeter and indicator light in cabinet door
- Redundant DC output contactors
- Connection terminals for external „emergency stop“
- Connection terminals for external „stop“
- DC output electrically isolated from the AC mains (galvanic isolation)
Interfaces
- 10 inch display with touch operation
- Modbus / TCP interface
- CAN interface
- VNC interface
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
- System cabinets in a special design
Rittal enclosures, special bases, enclosures on castors, special paint fi nishes, wire end marking. The I-TS can be adapted to a wide range of customer requirements and local conditions - Due to grid operarotor regulations, NA protection may be
required to monitor the grid quality for the MI-TSNA protection with grid analysis measuring device for power generation systems (VDE-AR-N 4105, VDE-AR-N 4110)
Aufgrund von Richtlinien des Netzbetreibers kann ein NA-Schutz zur Überwachung der Netzqualität für das MI-TS erforderlich sein - Water cooling including increased protection class IP54
Water cooling of the system cabinets is available to minimize waste heat to the room or to reduce noise. This also increases the protection class 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
