MODULES INFERS FOR INVESTIGATION
HARDWARE OPTION INTEGRATION
Modules of Imperix Energy Inverters are best put together in frames or enclosures that can be rack-mounted. This will ensure the maximum flexibility, in virtue of the modular nature of the power module.
Versatile 3U rack-mountable enclosure
If you prefer an appropriate ease of use, imperix can deliver pre-assembled enclosures with power supplies, as well as several other features. This means the development modules are easy to reach and can easily go in or out of the enclosure, enabling easy changes to topology.
Enclosure with full integration (4U)
If it is a priority to elegantly integrate the modules, it is also possible to have them enclosed within rack-mountable engineered boxes. This also ensures that no dangerous voltage may ever be present except with a 4mm laboratory safety plug. The 4U enclosures will also have an LCD stating the status of the modules and the temperatures of the internal components.
All-in-one inverter (1.5U)
In the case of two-level three-phase inverters, the topology is so ubiquitous that modularity and reusability of the module is not usually a factor. In fact, a compact all-in-one solution makes more sense because it reduces wiring, can facilitate better EMC performance. The TPI8032 includes a 22kW inverter power stage with passive filters, relays, voltage/current sensors, and B-Board PRO embedded controller.
