AT1-005-000-SP

Current Sensors Overview

The AT1-005-000-SP is an AC current transducer from the NK Technologies AT series, integrating a current transformer and signal conditioner into a single split-core package. It supports selectable full-scale ranges of 10A, 20A, or 50A. The device operates as a self-powered module requiring no external excitation voltage. It provides a 0–5VDC analog output signal proportional to the measured current. The unit is designed for unidirectional current monitoring applications.

Current Sensors Feature Summary

• Integrates current transformer and signal conditioning electronics within a single compact housing
• Features a split-core design enabling installation without disconnecting primary conductors
• Operates as a self-powered module eliminating the need for auxiliary supply voltages
• Provides factory-calibrated accuracy through matched component assembly

Current Sensors Applications

• Unidirectional AC current monitoring in industrial control panels
• Energy management systems requiring isolated current measurement
• Power distribution equipment with split-core installation requirements
• Automated machinery feedback loops for current sensing

Current Sensors Procurement Notes

Verify that the specific application requires a split-core configuration rather than a solid-core alternative. Confirm the necessary current range selection (10A, 20A, or 50A) matches the maximum expected load. Ensure the system interface accepts a 0–5VDC output signal. Check that the operating frequency falls within the specified 20–100 Hz range. Validate that the unidirectional nature of the sensor aligns with the circuit topology.

Current Sensors Selection Notes

Select this model when non-intrusive installation on existing busbars or cables is required. Choose the appropriate range variant based on the maximum continuous current to be monitored. Consider the split-core form factor for retrofits where conductor disconnection is impractical. Verify compatibility with downstream data acquisition systems accepting low-voltage DC signals. Evaluate space constraints against the physical dimensions of the split-core housing.

Current Sensors Part Context

This component belongs to the AT series of AC current transducers manufactured by NK Technologies. The series combines magnetic sensing elements with electronic conditioning circuits. The AT1-005-000-SP specifically denotes the split-core variant within this product line. Other variants include solid-core models such as the FT and FF suffixes. The series is designed for industrial-grade current measurement applications.

Current Sensors Replacement Considerations

Direct replacements are limited to other AT1-005-000-SP units or equivalent split-core transducers from the same manufacturer. Solid-core variants like AT1-005-000-FT require mechanical modification due to different core designs. Cross-manufacturer substitutes must match the 0–5VDC output, self-powered operation, and split-core geometry. Verify electrical isolation ratings and frequency response before substitution.
