SSA-2-250A

Current Sensors Overview

The SSA-2-250A is a bidirectional analog current sensor module from the Riedon SSA-2 Series by Bourns. It features a nominal current rating of 250 A and supports both AC and DC circuits. The device provides 1500 VDC reinforced isolation between input and output channels. Electrical specifications include a typical supply current of 40 mA and a tolerance of ±0.2%. The component operates within a temperature range of -40°C to +115°C (with some documentation citing up to 125°C) and utilizes chassis mounting for secure installation in industrial applications.

Current Sensors Feature Summary

• Bidirectional sensing capability for accurate measurement in both positive and negative current directions
• High voltage isolation providing 1500 VDC reinforced protection between circuit paths
• Precision tolerance ensuring reliable performance in demanding power monitoring scenarios

Current Sensors Applications

• Industrial power distribution systems requiring high-current monitoring
• Battery management systems utilizing AC or DC circuit architectures
• Motor drive control units needing bidirectional current feedback

Current Sensors Procurement Notes

Verify the specific datasheet version prior to ordering, as Bourns notes that specifications are subject to change without notice. Confirm that the required operating temperature range aligns with your application's thermal profile, particularly regarding the upper limit variance found in documentation. Ensure chassis mounting hardware compatibility is assessed during the integration phase to guarantee mechanical stability under operational conditions.

Current Sensors Selection Notes

Select this component when bidirectional current measurement is required for high-amperage applications up to 250 A. The 1500 VDC isolation makes it suitable for environments where galvanic separation is critical for safety and signal integrity. Consider the chassis mount form factor if panel integration is preferred over PCB surface mounting. Validate that the ±0.2% tolerance meets the precision requirements of your specific control loop or monitoring system.

Current Sensors Part Context

The SSA-2-250A belongs to the Riedon SSA-2 Series of analog current sensors, now integrated into Bourns' product portfolio. This series is designed for robust industrial use, offering a range of nominal currents from 100 A to 1000 A. The SSA-2 model specifically addresses mid-range high-current needs while maintaining the series' hallmark reliability and isolation standards for power electronics.

Current Sensors Replacement Considerations

Consult official Bourns/Riedon substitution guides for direct equivalents within the SSA-2 series or updated industrial shunt resistor models. Verify pinout and isolation voltage ratings match before substituting with other manufacturers' high-current sensors.
