2DRL-181

Overview

The Sifam Tinsley Instrumentation Inc. model 2DRL-181 is a current sense transformer designed for electrical measurement applications. It features a primary current rating of 180 A and a secondary output of 5 A. The device operates within a frequency range of 50 Hz to 400 Hz, accommodating various power system frequencies. It utilizes a free-hanging in-line mounting configuration, allowing for direct integration into conductor runs without requiring panel cutouts or DIN rail adapters.

Feature Summary

• Provides accurate current sensing for AC systems across a wide frequency spectrum
• Supports flexible installation through free-hanging in-line design
• Delivers standardized secondary output compatible with standard metering equipment

Applications

• Industrial power distribution monitoring
• Electrical panel current measurement
• Energy management system integration

Procurement Notes

Verify the specific application requirements against the 180 A primary rating and 50-400 Hz operational range before procurement. Confirm that the free-hanging in-line mounting style aligns with the physical installation constraints of the target circuit. Ensure compatibility with downstream instrumentation accepting 5 A secondary input. Cross-reference the part number 2DRL-181 with official manufacturer documentation to confirm current specifications and certification status prior to purchase.

Selection Notes

Select this component when an in-line current transformer is required for conductors carrying up to 180 A. The wide frequency response makes it suitable for non-standard power frequencies or harmonic-rich environments. Consider the physical space available for free-hanging installation versus panel-mounted alternatives. Evaluate the need for a 5 A secondary output to match existing metering infrastructure.
