5DRL-151

Overview

The Sifam Tinsley Instrumentation Inc. model 5DRL-151 is a current sense transformer designed for electrical measurement applications. It features a primary current rating of 150 A and a secondary output of 150:5. 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 circuits without panel enclosure requirements.

Feature Summary

• Provides accurate current sensing via a 150:5 transformation ratio
• Supports wide frequency operation from 50 Hz to 400 Hz
• Designed for free-hanging in-line installation

Applications

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

Procurement Notes

Verify the specific application frequency falls within the 50 Hz to 400 Hz operational range before procurement. Confirm that the primary current load does not exceed the 150 A rating. Ensure the installation environment supports the free-hanging in-line mounting style. Cross-reference the 150:5 secondary ratio with connected metering or relay inputs to guarantee compatibility.

Selection Notes

Select this component when a robust current sense transformer is required for frequencies up to 400 Hz. The 150 A primary rating suits moderate to high-current industrial circuits. The in-line design simplifies wiring compared to split-core alternatives. Consider the physical space required for free-hanging installation during system design.

Part Context

This part belongs to the current transformer category offered by Sifam Tinsley Instrumentation Inc. The manufacturer specializes in precision electrical measuring instruments and components. The 5DRL-151 serves as a dedicated sensing element rather than a complete display unit, providing isolated signal conversion for downstream instrumentation.
