DK 100 C420 U

Current Sensors Overview

The DK 100 C420 U is a split core transducer designed for the electronic measurement of DC current. It utilizes Hall effect technology with an open-loop configuration to provide galvanic isolation between the primary circuit and the secondary signal output. The device supports selectable primary current ratings of 50A, 75A, or 100A, allowing for flexible application across various power levels. It operates within a temperature range of -20°C to 50°C and features a response time of 20ms. The unit is unidirectional and intended for single pass-through installation.

Current Sensors Feature Summary

• Split core design facilitates easy installation on existing busbars without disconnecting conductors
• Provides galvanic isolation between high voltage primary circuits and low voltage secondary signals
• Utilizes Hall effect sensing technology for accurate DC current measurement
• Supports selectable primary current ratings to accommodate different load requirements

Current Sensors Applications

• DC current monitoring in industrial power supplies
• Battery management systems requiring isolated current feedback
• Electric vehicle charging infrastructure components
• Uninterruptible power supply (UPS) systems

Current Sensors Procurement Notes

Verify the specific selectable current rating required for your application during procurement, as the model designation indicates support for multiple amperage options. Confirm that the split core mechanism matches the physical dimensions of the conductor being measured. Ensure the operating environment remains within the specified temperature limits to maintain accuracy. Check for any necessary DIN rail adapters if mounting constraints apply.

Current Sensors Selection Notes

Select this component when isolated DC current measurement is required without breaking the primary circuit. The split core architecture is essential for retrofitting or installing sensors on fixed busbars. Consider the selectable current ratings to ensure the sensor covers the maximum expected load. Verify that the unidirectional nature aligns with the current flow direction in the target system.

Current Sensors Part Context

This part belongs to the DK-C series of current sensors manufactured by LEM USA Inc. The series is characterized by its split core construction and Hall effect operation. Variants within the series may differ in housing style or specific electrical parameters, but share the fundamental capability for isolated DC measurement.
