2DRL-201

Overview

The Sifam Tinsley Instrumentation Inc 2DRL-201 is a current sense transformer designed for in-line applications. It features a primary current rating of 200 A and a secondary output of 5 A, resulting in a 200:5 ratio. The unit operates within a frequency range of 50Hz to 400Hz. Its physical dimensions include a maximum installed height of 1.750 inches (44.45mm). The device utilizes a donut-style core with a 1-inch inner diameter.

Feature Summary

• Free hanging in-line installation configuration
• Donut core design with 1-inch inner diameter
• Wide frequency spectrum capability

Applications

• Power monitoring systems
• Industrial control circuits
• Electrical protection schemes

Procurement Notes

Verify the specific part number against manufacturer documentation to ensure compatibility with existing system requirements. Confirm that the 200:5 ratio and 50Hz-400Hz frequency range align with the intended application parameters before procurement.

Selection Notes

Select this component when an in-line current sensing solution is required for frequencies between 50Hz and 400Hz. Ensure the primary circuit current does not exceed 200 A and that the physical space accommodates the specified height and inner diameter constraints.

Part Context

This model belongs to the ANSI CT series from Sifam Tinsley Instrumentation Inc. It is categorized as a current sense transformer, distinct from panel meters or standard power transformers. The design focuses on precise current measurement for instrumentation purposes.

Replacement Considerations

Ensure any substitute maintains the 200:5 ratio and 1-inch ID. Verify frequency response matches the 50Hz-400Hz requirement. Physical mounting constraints must be compatible with the free-hanging in-line format.
