5SFT-500

Current Sense Transformers Overview

The Sifam Tinsley Instrumentation Inc. model 5SFT-500 is a non-invasive solid core current transformer designed for electrical measurement applications. It features a primary current rating of 50 A and a secondary output of 5 A, resulting in a 10:1 current ratio. The device operates within a frequency range of 50 Hz to 400 Hz and supports an accuracy class of 2 with a burden capacity of 1 VA. It includes a 40 mm window aperture for conductor passage.

Current Sense Transformers Feature Summary

• Non-invasive solid core design allows for efficient current measurement without disconnecting the conductor.

Current Sense Transformers Applications

• Electrical current monitoring in industrial systems
• Power distribution network measurement
• Energy metering integration

Current Sense Transformers Procurement Notes

Verify that the required primary current does not exceed 50 A and the operating frequency falls within the 50 Hz to 400 Hz range. Confirm that the connected burden remains within the 1 VA limit to maintain Class 2 accuracy. Ensure the conductor diameter fits within the 40 mm window aperture for proper installation.

Current Sense Transformers Selection Notes

Select this component when a split-core or solid core solution is needed for currents up to 50 A. It is suitable for frequencies extending up to 400 Hz, distinguishing it from standard 60 Hz only units. Consider the 10:1 ratio for compatibility with downstream instrumentation requiring 5 A inputs.

Current Sense Transformers Part Context

This part belongs to the Sifam Tinsley current transformer portfolio, which provides reliable sensing solutions for power management.
