2DRL-1250

Overview

The Sifam Tinsley Instrumentation Inc. 2DRL-1250 is a current sense transformer designed for high-current measurement applications. It features a primary rating of 125 A and a turns ratio of 125:5, providing a secondary output suitable for standard instrumentation inputs. The device operates within a frequency range of 50 Hz to 400 Hz, ensuring accurate performance across typical power line frequencies and higher harmonic content. Constructed as a free-hanging in-line unit, it allows for direct integration into busbar or cable runs without requiring additional mounting hardware.

Feature Summary

• Provides precise current sensing via a 125:5 transformation ratio
• Supports operation across a wide frequency spectrum from 50 Hz to 400 Hz
• Designed for free-hanging in-line installation for flexible system integration

Applications

• Industrial power monitoring systems
• Electrical panel metering circuits
• Current transducer input stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's coding table to ensure compatibility with required secondary current ratings and physical dimensions. Confirm that the 125 A primary rating aligns with the maximum expected load current in the target application circuit to prevent saturation or accuracy loss during peak operations.

Selection Notes

Select this component when a robust, non-invasive current measurement solution is required for currents up to 125 A. The wide frequency response makes it suitable for applications involving variable frequency drives or harmonics. Ensure the installation environment supports free-hanging mounting and that the secondary burden matches the connected measuring instrument's impedance requirements.

Part Context

This model belongs to the Sifam Tinsley 2RL series of current transformers, which are widely used in precision electrical instrumentation. The series offers various primary current ratings to accommodate different industrial loads. The 2DRL-1250 specifically addresses medium-high current applications where isolation and accuracy are critical for safe and reliable power management.

Replacement Considerations

Cross-reference part numbers such as 2RL-1250 for potential equivalents within the same product family. Verify that any substitute maintains identical primary current ratings, frequency ranges, and physical form factors to ensure seamless integration without modifying existing wiring or mounting structures.
