Profile:

Built around a 7-inch TFT touchscreen and advanced amplitude-stabilized amplifier technology, the KDGK-703S delivers exceptional stability, fine resolution, and flexible output control. With support for percentage-based, digit-by-digit, or encoder-adjusted settings—and optional 1000A clamp meter calibration—it combines laboratory-grade performance with field-ready usability in a compact 10 kg chassis.

Features:

  • 7-inch TFT Touchscreen (800×480): Intuitive menu navigation and real-time parameter display
  • Multi-mode Output Control:
    • Direct value entry
    • Step adjustment (N = 2, 3, 4, 5, 6, 8, 10, 15)
    • Digit-by-digit tuning via cursor navigation
  • Clamp Meter Calibration: Optional 1000A coil enables direct calibration of clamp-on ammeters (0–1000 A)
  • High Stability & Low Distortion:
    • DC stability: ≤0.01% of full scale per minute
    • AC stability: ≤0.02% of full scale per minute
    • AC THD: ≤0.5%
    • DC ripple: ≤0.5%
  • Temperature Compensation: Output drift ≤0.002%/°C outside 20°C ±2°C
  • Six-Digit Display: Precise readout of set values and operating parameters
  • Safety & Reliability: Overload protection, robust load capability, and continuous operation support
