19SHT 102

Overview

The Sifam Tinsley Instrumentation Inc. model 19SHT 102 is a solid core AC current transformer belonging to the Omega 30 series. It features a chassis mount design with an internal diameter of 4.25 inches (approximately 108 mm). The device supports a primary current rating of 1000 A and provides a secondary output of 5 A, establishing a transformation ratio of 200:1. It operates within a frequency range of 50 Hz to 400 Hz and maintains an accuracy class of +/- 1%. The unit utilizes an 8-32 terminal stud with nut for electrical connections.

Feature Summary

• Solid core construction designed for direct cable passage without disconnection
• Chassis mounting configuration with integrated terminal studs for secure installation
• Wide frequency operational capability supporting both power and aerospace spectrum requirements

Applications

• Industrial power monitoring systems requiring high-current measurement
• Aerospace ground support equipment testing and diagnostics
• Electrical distribution panel metering and protection circuits

Procurement Notes

Verify that the required aperture size matches the 4.25-inch internal diameter specification before ordering. Confirm that the application environment falls within the 50 Hz to 400 Hz operating frequency range. Ensure the mounting surface accommodates the chassis mount footprint and that the 8-32 terminal stud interface aligns with existing wiring harnesses or busbar connections. Cross-reference the 1000 A primary rating against peak load conditions to prevent saturation.

Selection Notes

Select this component when a robust, non-intrusive current sensing solution is needed for conductors up to 4.25 inches in diameter. The 1000:5 ratio suits applications where standard 5 A instrumentation inputs are utilized. Consider the chassis mount style if panel integration is preferred over DIN rail or wall mounting alternatives found in other series.

Part Context

This part belongs to the Omega 30 series of current transformers from Sifam Tinsley. Unlike the Omega 10 series which offers various aperture sizes, the Omega 30 line typically focuses on larger apertures suitable for heavy-duty cables. The 19SHT 102 specifically addresses high-current industrial environments where precise phase-aligned measurement is critical for energy management.
