Profile:

The KDHL-100A integrates a precision 100A constant-current source, 5-digit micro-ohm measurement system, and intelligent data management into a compact 8.5 kg chassis. With automatic current regulation, thermal-noise suppression, and dual-range capability (100A/50A), it ensures laboratory-grade accuracy even in noisy field environments. Its Windows-style menu, built-in printer, USB storage, and real-time clock make data traceability simple—ideal for modern digital substation workflows.

Features:

✅ High Accuracy & Wide Range: ±(0.5% rdg + 0.2 µΩ); measures down to 0.0001 µΩ
✅ Dual Test Currents100A (0–40 mΩ) or 50A (0–80 mΩ) for flexible application
✅ 5" Color Touchscreen: 65K-color display with intuitive Windows-style interface
✅ Fast & Stable Output: Precision 100A switch-mode power supply with auto-regulation
✅ Onboard Data Management: Stores 500 test records in non-volatile memory
✅ Built-in Thermal Printer: Instantly prints results on-site
✅ USB Export: Supports U-disk data transfer for reporting and analysis
✅ Real-Time Clock: Timestamps every test for audit and traceability
✅ Portable Design: Lightweight (8.5 kg), rugged, and easy to carry to any bay
