Power Choke Tester DPG10 – 2000B

The DPG10-2000B is a high-current Power Choke Tester from the DPG10 series, designed to measure inductance, flux linkage, magnetic co-energy, and DC resistance of inductors, chokes and power transformers under realistic pulsed-current conditions. With up to 2000 A test current in its highest range, it is ideal for medium-to-large power inductive components used in converters, inverters, PFC circuits, power supplies, and other power-electronics systems..

The DPG10-2000B uses a pulsed-impulse measurement method: a controlled voltage pulse is applied to the device under test, causing current to ramp up according to the inductance. The tester samples voltage and current waveforms at high speed and computes inductance as a function of current (L(i)), as well as flux linkage, co-energy and DC resistance.

Thanks to its wide adjustable pulse width and high current capacity, the DPG10-2000B can characterize inductors and chokes over a broad range — from high-frequency ferrites needing short pulses to large low-frequency iron cores or power reactors requiring longer pulses. The full L(i) curve reveals how inductance changes (including saturation) under real load conditions, offering insight into real-world behavior.

The instrument’s DC resistance measurement helps evaluate winding resistance, copper losses and verify coil integrity. Combined with inductance curves, this makes the DPG10-2000B a comprehensive tool for design validation, quality inspection, and production testing of inductive components.

  • Supports current ranges including up to 2000 A.

  • Adjustable pulse voltage (10 V to 400 V) for flexible test conditions.

  • Adjustable pulse width from roughly 3 microseconds up to 1 second to suit a wide variety of core materials.

  • Measures incremental and secant inductance, flux linkage, magnetic co-energy and DC resistance.

  • Generates full inductance curves L(i), enabling clear observation of saturation behaviour and realistic in-circuit performance.

  • Compatible with large power chokes and reactors — from small filter inductors to heavy-duty power reactors.

  • Comes with PC software and full accessory set for lab or production-line use.
