Under/Over Voltage Relay Trainer (Model: XPO-PRT/UOV)

The Under/Over Voltage Relay Trainer (Model: XPO-PRT/UOV) is a comprehensive educational tool designed to facilitate in-depth studies on the characteristics of under and overvoltage relays. Equipped with a built-in relay testing kit, this trainer includes essential components such as a voltage injector, current injector, elapsed time counter with 1-millisecond resolution, trip relay logic, and more, eliminating the need for a separate testing kit. Enhancing the learning experience, the trainer comes with a set of 7-8 associated relay testing panels, mounted in a lightweight and sturdy aluminum profile flat demo panel system. The use of 4mm sturdy shrouded banana patch cords and shrouded socket arrangements for high-voltage circuits ensures easy and safe wiring, making it suitable for student use.
