2DRL-401

Overview

The Sifam Tinsley Instrumentation Inc. model 2DRL-401 is a current sense transformer designed for electrical measurement applications. It features a rated primary current of 400 A and provides a secondary output of 400:5. The device operates within a frequency range of 50 Hz to 400 Hz. It utilizes a free-hanging in-line mounting configuration, allowing for direct integration into power lines without panel cutouts.

Feature Summary

• Provides accurate current sensing via a 400:5 transformation ratio
• Supports wide frequency operation from 50 Hz to 400 Hz
• Utilizes a free-hanging in-line design for flexible installation

Applications

• Industrial power monitoring systems
• Electrical distribution panels
• Current sensing for protective relays

Procurement Notes

Verify the specific winding configuration and insulation class against the official manufacturer datasheet before procurement. Ensure the operating frequency range aligns with the system requirements. Confirm mechanical dimensions for clearance in the intended in-line mounting location. Cross-reference the part number with authorized distributors to ensure authenticity and compliance with international safety standards.

Selection Notes

Select this component when a robust, high-current sensing solution is required for frequencies up to 400 Hz. The in-line form factor is suitable for retrofitting or new installations where space constraints preclude traditional panel meters. Consider the 400:5 ratio compatibility with downstream instrumentation inputs. Evaluate environmental conditions to ensure the transformer's thermal rating meets operational demands.
