Profile:

Built on next-generation power electronics, the KDJB-430A achieves exceptional power density while retaining the waveform fidelity of traditional large-scale testers. Its A4-sized chassis (just 7.2 kg) integrates a stable Android OS, dual communication options (Wi-Fi, Bluetooth, Ethernet), and a user-centric interface—making complex protection tests intuitive, efficient, and highly mobile.

Features:

  • 10.5-inch Full HD Touchscreen: 1920×1280 resolution for clear visualization and one-handed operation
  • Android-Based Smart OS: Intuitive UI with responsive human-machine interaction
  • High-Fidelity Signal Generation: Dual-core DSP + high-resolution D/A converters ensure smooth, distortion-free waveforms
  • Flexible Connectivity: Built-in Wi-Fi, Bluetooth, and standard Ethernet for remote control and data transfer
  • Ultra-Portable Design: Dimensions slightly larger than A4 paper (340 × 230 × 125 mm), weight ≤7.2 kg
  • Integrated DC Auxiliary Power: Selectable +110V or +220V output for relay logic supply
  • Standard Output Configuration:
    • 4-phase voltage (0–130V AC)
    • 3-phase current (0–30A AC)
  • Advanced Thermal Management: Optimized airflow for sustained performance in field conditions
