  • Specification

The DPG10-4000B/F uses a controlled voltage-pulse test method to analyze the true performance of inductive components. When a voltage pulse is applied, the current rises according to the inductance. The device captures both voltage and current waveforms and calculates L(i), flux linkage, magnetic co-energy and DC resistance.

With its massive 4000 A current capability and 8000 J energy rating, this model is designed for very large inductors, power reactors and transformers found in railway systems, heavy-duty industrial converters, large inverters, and high-power grid equipment. Despite this high power, it can still test smaller components using lower current ranges, making it versatile for engineering labs and production environments.

Its wide pulse-width range ensures accurate testing of different magnetic materials, from high-frequency ferrites to large laminated iron cores. The broad DC resistance range is ideal for verifying low-resistance windings on high-current coils as well as mid-range inductors.

  • Supports extremely high test currents up to 4000 A

  • Very high pulse-energy handling up to 8000 J

  • Adjustable pulse voltage from 10 V to 400 V

  • Pulse-width control from approximately 3 µs to 1 s

  • Measures inductance curve L(i), incremental and secant inductance, flux linkage, magnetic co-energy and DC resistance

  • DC resistance measurement range from 0.01 mΩ to 35 Ω

  • Suitable for very large, high-energy inductive components such as power reactors and industrial transformers

  • Compact size for its capability: 470 × 500 × 167 mm

  • Delivered as a complete testing solution with cables, software and calibration certificate
