101990028

Overview

The Seeed Technology Co., Ltd part number 101990028 is a current sense transformer designed for chassis mounting. It features a turns ratio of 1800:1 and supports a maximum current rating of 30A. This component serves as an electrical isolation device for monitoring alternating current in power systems.

Feature Summary

• Provides galvanic isolation between primary high-current circuits and secondary sensing electronics
• Engineered for direct chassis mounting to facilitate integration into industrial enclosures
• Capable of handling continuous currents up to 30A for robust power monitoring applications

Applications

• Alternating current measurement in industrial power distribution panels
• Chassis-mounted energy monitoring systems requiring electrical isolation
• Protection circuits in AC power supplies utilizing current sensing transformers

Procurement Notes

Verify the specific datasheet for the 101990028 to confirm mechanical dimensions and terminal configurations before integration. Ensure the application voltage and frequency ranges align with the transformer's rated specifications. Confirm that the 30A current rating meets the peak load requirements of the target circuit without saturation.

Selection Notes

Select this component when a high-isolation current sensor is required for AC applications. The 1800:1 ratio provides a scaled-down signal suitable for standard analog-to-digital conversion or amplifier inputs. Consider the chassis mount form factor if space constraints within an enclosure dictate panel installation rather than PCB mounting.

Part Context

This part belongs to the category of current sense transformers manufactured by Seeed Technology Co., Ltd. It is distinct from integrated Hall-effect sensors, relying instead on magnetic induction for non-contact current measurement. The product is categorized under electronic components used for power management and monitoring.
