INVERTRONIC – single-phase and three-phase inverter systems
Maximum uptime for process-critical consumers in industry
Far-reaching budgeting and financial repercussions can arise as the result of faults on the area of power supply. Due to disturbances on the public power supply system caused by repercussions from large-scale consumers, and due to energisation events during peak consumption periods – or in the event of lightning strikes – it’s impossible to prevent these irregularities from occurring. These will result in voltage dips, overshoots and transients in the public grid voltage. These may exert a considerable influence on the availability of connected consumers, giving rise to process faults or production failures.
For the supply of power to consumers requiring AC power which is independent of faults arising on the public grid, BENNING offers very robust, single-phase and three-phase inverter systems – in the form of the INVERTRONIC power inverter – for the tough applications that come up in industry, typically for:
These are connected up to AC power grids that are supported (e.g. by batteries) and provide a reliable source of good quality electrical power to critical consumers.
- High quality of output voltage
- True sinewave output
- Low output ripple
- Good control dynamics even during rapid load cycles, thus no overshoot/undershoot with consumer voltage
- Marked improvement in quality of voltage and frequency – by comparison with standard grade – and this results in a reduction of stress on consumers
- Digitally regulated switching concept
- Can be configured rapidly
- Low parts count
- Straightforward optical and digital interfaces
- Extensive reporting and monitoring functions
- Internal controllers
- All currently used interfaces are available, e.g. remote monitoring/modem control, HTML or SNMP, MODBus or Profibus etc.
- Output expansion or redundancy configuration by parallel switching of up to 8 individual systems with smart bus connection
- Straightforward coupling of A and B rails via coupling switch with no interim changeover to bypass mode
- Using any battery and rectifier infrastructure that’s already in place

INVERTRONIC – technical details
Parallel Operation
For redundancy or increased output power, up to eight INVERTRONIC units can be connected in parallel, operating in an active load-sharing mode. Half load parallel operation is achieved using two separate bus bars, connected with a coupling switch. The state of the coupling switch is relayed to the microprocessor, via an auxiliary contact.
Straightforward coupling without using bypass mode
INVERTRONIC power inverters use section switches directly and without having to switch over to bypass mode. The switching process is controlled by corresponding logic, thus dispensing with the need for complex switching routines. All consumers remain isolated from the public grid and receive a continuous supply of the best quality of power.
Option
For power plant applications where higher than normal fault clearing current is required, it is possible to specify an option for 7 x I nominal system output. Depending on the output power, a bigger cabinet may be required.

Easy, reliable operation combined with comprehensive reporting and monitoring functions
Display and control unit
The Monitoring Control Unit 3000 (MCU 3000) is used to operate and remotely monitor the inverter. It is consistently tailored to the needs of the user and provides all the necessary measurement and setting values in a straightforward and user-friendly manner. Only the information required to perform the task at hand is displayed on the screen. The operation becomes safer and more efficient. The time required for service and maintenance processes is significantly reduced.
Actions or service processes are automatically triggered by events via individually adjustable limit values, filters and prioritisation. In addition, a hysteresis range can be defined for alarms and messages.
Among other things, the MCU 3000 has an integrated web server and thus enables connection to various network topologies in addition to remote maintenance.
