Profile:

Built on a stable Linux OS and powered by an internal lithium battery, the KDJB-650S delivers lab-grade accuracy (0.05% typical) in a rugged handheld form. It features 6-phase current (up to 40A) and 6-phase voltage (130V) with ultra-low distortion (<0.1%) and microsecond-level synchronization. Equipped with 4 fiber Ethernet ports (including 1 GbE), ST serial optics, and multiple communication interfaces (Wi-Fi, Bluetooth, 4G optional), it supports real-time cloud template updates, remote diagnostics, and seamless data exchange. The integrated thermal management ensures stable performance during prolonged high-power output.
