Current Sensors datasheet and documents for CR4210S-70

CR4210S-70

Current Sensors Overview

The CR4210S-70 is a self-powered AC current transducer from the CR Magnetics Inc. CR4210S series, designed for measuring alternating current in electrical systems. It features a split-core design allowing installation without disconnecting conductors. The device provides a proportional 0-5 Vdc output signal derived directly from the sensed current, eliminating the need for an external power supply. It supports an input range of 0-70 AAC and operates within a frequency range of 50-400 Hz. The unit offers high isolation with a dielectric strength of 2500 VDC and requires an output load of at least 1M ohm to function correctly.

Current Sensors Feature Summary

Self-powered operation utilizing energy from the measured current
Split-core construction for non-intrusive conductor installation
Proportional 0-5 Vdc analog voltage output signal
High voltage isolation capability between primary and secondary circuits

Current Sensors Applications

Industrial power distribution panels
Electrical substations
Mechanical control systems
AC current monitoring equipment

Current Sensors Procurement Notes

Verify that the application circuit provides an output load impedance of no less than 1M ohm to ensure accurate signal transmission. Confirm that the measured current remains within the 0-70 AAC range and that the system frequency falls between 50-400 Hz. Ensure proper insulation clearance for the 2500 VDC isolation rating during installation.

Current Sensors Selection Notes

Select this model when a self-powered solution is required to simplify wiring by removing the need for auxiliary power supplies. Choose the CR4210S-70 specifically for applications involving AC currents up to 70A where a voltage output is preferred over current loop outputs. Consider the split-core form factor if retrofitting existing installations without breaking the main conductor path is necessary.

Current Sensors Part Context

This component belongs to the CR4210S series of self-powered AC current transducers manufactured by CR Magnetics Inc. The series is engineered for robust performance in industrial environments, offering reliable current measurement through transformer-based conditioning. Unlike loop-powered alternatives such as the CR4220S series, this module derives its operating energy directly from the primary circuit.
