Overview: This document provides technical specifications and pricing for three-phase commutating chokes, specifically the DDK series, designed for inverter applications. The chokes are compliant with IEC/EN 61558-2-20 and VDE 0570-2-20 standards.

Dimensions and Weight: The document lists detailed dimensions for various DDK models, including parameters such as copper losses, total weight, and specific dimensions (a, b, b1, c, d, e, f, h, i). These dimensions are crucial for determining the precise height and depth of the chokes based on their data.

Inductivity and Pricing: The document provides a table with inductivity values (L), order numbers, and prices per unit for each DDK model. Prices vary significantly across models, reflecting differences in specifications and capabilities.
