Meet CATS Ki

CATS Ki is the first comprehensive set of evaluation and compliance tools designed for performance testing and evaluation of wireless power devices within the emerging Cordless Kitchen specification from the Wireless Power Consortium (WPC).

The CATS Ki system includes two primary units: the Test Power Receiver (TPR), with separate load boxes to test a transmitter, and the Test Power Transmitter (TPT) to test a receiver. In addition to this core configuration, the system connects to a host computer via a USB connection, and it features a dynamic user interface that provides adjustable settings and parameters to fit individual product development and evaluation needs.
