Profile:

Designed with high-frequency switching power supply and digital circuit technologies, it offers 4 fixed DC current outputs (50A/100A/150A/200A) for direct resistance measurement. Features accurate results, stable performance and digital display, meeting on-site maintenance and factory testing needs.

Features:

  1. Continuous large current output effectively breaks through contact oxide films, avoiding drawbacks of pulsed power.
  2. Strong anti-interference: The last digit of LCD stabilizes within ±1 word under severe interference, ensuring stable reading and good repeatability.
  3. Long service life: High-precision resistors eliminate temperature impacts; military-grade connectors enhance vibration resistance.
  4. Portable design: Compact size and lightweight, convenient for on-site carrying and operation.
