7020-01039-0

Current Sense Transformers Overview

The Murata Power Solutions Inc. model 7020-01039-0 is an industrial current transformer designed for AC current sensing applications. It features a primary-to-secondary turns ratio of 150:5A and provides a rated burden capacity of 6VA. The device supports a secondary output current of 5 Amps and operates within a frequency range of 50Hz to 400Hz. This component utilizes a free-hanging in-line mounting configuration, allowing for direct integration into power lines without requiring PCB footprint constraints.

Current Sense Transformers Feature Summary

• Provides accurate AC current sensing with a 150:5A transformation ratio
• Supports standard industrial frequencies from 50Hz to 400Hz
• Features a 6VA rated burden capacity for flexible circuit interfacing
• Utilizes a free-hanging in-line mechanical design for easy installation

Current Sense Transformers Applications

• Industrial power monitoring systems
• AC current measurement instrumentation
• Energy management and metering devices
• Power quality analysis equipment

Current Sense Transformers Procurement Notes

Verify the specific application requirements against the 50Hz to 400Hz operating frequency range to ensure compatibility with the target power system. Confirm that the connected burden does not exceed the 6VA rating to maintain accuracy. Ensure the physical dimensions allow for the required free-hanging in-line clearance during installation. Cross-reference the 150:5A ratio with existing sensor calibration data.

Current Sense Transformers Selection Notes

Select this component when high-current AC monitoring is required without direct electrical isolation barriers typical of Hall effect sensors. The 150:5A ratio suits applications where the primary current significantly exceeds standard signal levels. Consider the in-line form factor if space constraints prohibit through-hole or surface-mount alternatives. Evaluate the 6VA burden capability against the impedance of the downstream measurement circuitry.

Current Sense Transformers Part Context

This part belongs to the industrial current sense transformer category from Murata Power Solutions. It serves as a passive magnetic component for converting high AC currents to standardized low-level signals. Unlike solid-state sensors, it relies on electromagnetic induction, offering inherent galvanic isolation between the primary conductor and the secondary measurement circuit.

Current Sense Transformers Replacement Considerations

Substitute parts must match the 150:5A ratio, 6VA burden, and 50-400Hz frequency range. Verify mechanical compatibility for free-hanging in-line mounting. Check for equivalent isolation ratings and thermal performance characteristics.
