21803-011-02

The Allen Bradley 21803-011-02 is a high-performance DC link choke designed for various industrial applications. This component is rated to handle a continuous direct current of 160A, making it suitable for heavy-duty operations. It delivers an inductance of 320 µH, which plays a vital role in managing electrical flows and reducing ripple currents in power electronics.

Constructed with heavy-gauge copper for its windings, this choke provides optimal conductivity and efficiency. The core of the choke is made of silicon steel, known for its superior magnetic properties. Termination is accomplished via lugs, facilitating straightforward connections in installation.

This model features an open style that is mountable, allowing integration into a variety of setups without proprietary housing. Class H insulation ensures it can withstand higher temperatures, and the degree of protection is rated as IP20. This means it is protected against solid objects larger than 12.5 mm but is not waterproof.

For effective operation, the choke can function in environments with relative humidity levels ranging from 5% to 95%, non-condensing. Its operating temperature range runs from 0 to 50°C, while it can withstand storage conditions from -40 to 85°C. The device also offers natural convection cooling, ensuring that it remains within safe operating conditions. Given its vibration resistance of 2 G, this choke maintains stability under various mechanical stresses, contributing to its overall reliability.
