Product catalog summary
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.
Specifications:
- Insulation Class: B / F from 3.2 kVA
- Ambient Temperature: -25 to 40 °C
- Connection Terminal: Suitable for currents less than 63 A
- Frequency: 50/60 Hz
Dimensions and Weight: The document lists various models of DDK chokes with detailed dimensions (a, b, b1, c, d, e, f, h, i) and total weight in kilograms. Dimensions are provided in millimeters, and the weight varies depending on the model.
Inductivity and Pricing: Each model is associated with specific inductivity values (L) and prices per unit. The document includes a table with order numbers, inductivity values, and corresponding prices in Euros.
Key Notes:
- Connection lugs are specified, and dimensions are dependent on rated current and terminal lugs used.
- Precise height and depth are determined based on choke data, including the number of windings and set air core.
- Material surcharge details are referenced on page 64.
