3 Phase Inverter Trainer (Model : XPO-INV)

Rated 0 out of 5

The XPO-INV is reconfigurable hardware modules and replaceable power modules, allowing users to construct 3-phase/1-phase inverter topologies. The FPGA controller board’s accessibility promotes quick verification and testing of innovative ideas. The PE7 panel features a square wave (quasi-sine) default and weighted sine PWM inverter selection switch. Optional use of hall sensors for voltage/current measurements adds versatility. The demo panel setup is lightweight yet sturdy, utilizing a table-top aluminium profile with plastic modular panels. These panels house various high-voltage components, incorporating colourful overlays for safety and easy servicing. The inclusion of 4mm shrouded banana patch cords facilitates easy and safe wiring for students. Each panel, with ABS moulded plastic enclosure and colourful screwless overlays displaying circuit diagrams and connection tag numbers, ensures easy understanding and connections.
