Profile:

The KDJB-1200Y combines advanced digital signal processing, high-fidelity linear amplification, and an all-in-one embedded design to deliver unmatched reliability and precision. Built with a 10.1-inch color touchscreen and a rugged industrial computer, it operates independently—no external PC required. With built-in WiFi, dual Ethernet, GPS synchronization, and USB connectivity, the KDJB-1200Y offers seamless control whether used in the lab or at remote substations. It’s the ideal solution for engineers who demand speed, accuracy, and flexibility in protection system testing.

Features:

Six-Phase Flexibility: 6×30A AC current + 6×120V AC voltage + 6×±10A/±160V DC — perfect for differential, ATS, and complex protection schemes
High-Fidelity Linear Amplifiers: No switching noise; smooth, low-distortion waveforms across full range (µA to 30A)
True All-in-One Design: Integrated 10.1" touchscreen, industrial PC, WiFi, dual RJ45, GPS, and USB — eliminates need for external laptop
Ultra-Fast Outputs: 4 fast开出 (≤0.01ms) + 4 conventional开出 (≤1ms) for precise trip/close timing simulation
Intelligent Software: Automated test sequences, fault replay, real-time vector diagrams, report generation, and U盘 data backup
Field-Optimized: Lightweight (19 kg), built-in 110V/220V auxiliary DC supply, and comprehensive protection (overload, overheat, short-circuit)
