2SHT-500

Overview

The Sifam Tinsley Instrumentation Inc. 2SHT-500 is a current sense transformer designed for chassis mounting applications. It features a primary-to-secondary turns ratio of 50:5, providing a secondary output current of 5A from a primary rating of 50A. The device operates within a frequency range of 50Hz to 400Hz and utilizes a solid core, non-invasive construction method.

Feature Summary

• Provides accurate current sensing via a fixed 50:5 transformation ratio
• Supports operation across a wide frequency spectrum from 50Hz to 400Hz
• Utilizes a solid core design for non-invasive installation on busbars or cables

Applications

• Industrial power monitoring systems requiring precise current measurement
• Electrical protection relays and circuit breaker control circuits
• Energy management and metering equipment in industrial settings

Procurement Notes

Verify the specific datasheet version for accuracy regarding burden resistance and saturation limits before integration. Confirm that the chassis mounting hardware requirements align with the installation panel specifications. Ensure the operating frequency range of 50Hz to 400Hz matches the system's electrical environment to maintain measurement integrity.

Selection Notes

Select this component when a robust, non-invasive current sensing solution is required for high-current applications up to 50A. The 5A secondary output is compatible with standard industrial meters and relay inputs. Consider the chassis mount form factor for permanent installations where space constraints allow for direct panel attachment rather than split-core flexibility.

Part Context

This model belongs to the current sense transformer category manufactured by Sifam Tinsley Instrumentation Inc. It serves as a critical interface between high-current primary conductors and low-current secondary measurement devices. The solid core design distinguishes it from split-core variants, offering potentially higher stability for fixed installations.
