Power Electronics Trainer (Model : XPO-PE) / XPO-1 Ph. PE)

Introducing XPO-PE, the microcontroller-based Power Electronics Trainer. This system features an aesthetically designed electronic desk with a master unit providing essential experiment resources, including line-synchronized firing circuits, power supplies, lamp loads, RLC loads, and battery charging supply. The central slot accommodates replaceable experiment panels, secured in sturdy ABS moulded plastic enclosures with colourful, screwless overlays depicting circuits. Connectivity is simplified through robust 4mm banana sockets and patch cords. Each multi-experiment panel comes with a set of comprehensive User Guides. To enhance the learning experience, consider ordering 6 Master units with sets of 6 panels (PE 1 x 2, PE2, PE3, PE6 x 2 nose), along with the Power Scope. Emphasize PE1 and PE6, the major panels, for an optimal understanding of power electronics concepts.
