ed-k’s product lineup delivers advanced measurement and testing solutions designed for inductive power components across development, manufacturing, and quality-control phases. The core offering — the Power Choke Tester DPG family — is built around a large-signal impulse measurement method that produces a full inductance curve as a function of current (L(i)) or the applied voltage-time integral (L(∫U dt)). This lets engineers instantly visualize saturation behavior and dynamic inductance characteristics under real-world conditions.

Beyond basic differential and amplitude inductance, ed-k instruments can measure flux linkage, magnetic co-energy, DC resistance, and compute flux density — offering a comprehensive evaluation of magnetic components.

To serve diverse applications, the catalog includes:

• DPG10 and DPG20 series Power Choke Testers (for a wide current range, core types, small SMD inductors to large power inductors).

• 3-Phase Extension Units for testing three-phase chokes

• Dedicated software for measurement control, data logging, export (e.g. XML/CSV/PDF), suitable for both lab-based and automated production environments.

• Measurement leads, accessories and optional add-ons

• Pulse Current Source (PCS10 series) for dynamic tests

• Supporting tools and documentation for integrating into quality control or production workflows

Whether you are designing small inductors for switching supplies, validating filter chokes for converters, or testing large power inductors and transformers, this product catalog offers a unified measurement solution. With ed-k instruments you get fast, portable, and cost-effective measurement set-ups capable of handling currents up to 10,000 A — making them suitable for everything from SMD-sized inductors to high-power magnetic components.
