SSA-2-1000A

Current Sensors Overview

The SSA-2-1000A is a bidirectional analog current sensor from the Riedon SSA-2 series, designed for measuring DC currents up to 1000 A. It features a shunt-based architecture with a tolerance of ±0.2% and operates within a supply voltage range of 3 V to 5.5 V. The device supports a maximum operating frequency of 300 kHz and has a response time of 1.6 µs. It draws a typical supply current of 40 mA and functions reliably across an extended temperature range of -40°C to +85°C. The module utilizes a base-mount package with dimensions of 84 mm in length and 68.7 mm in width.

Current Sensors Feature Summary

• Bidirectional measurement capability for accurate current sensing in both directions
• High precision with a specified tolerance of ±0.2%
• Resilient connector design integrated into a small, lightweight module
• Wide operating frequency support up to 300 kHz

Current Sensors Applications

• Industrial power monitoring systems
• Renewable energy inverter control circuits
• Electric vehicle battery management systems
• High-current motor drive applications

Current Sensors Procurement Notes

Verify that the specific suffix 'A' matches the required pinout and connector configuration for your PCB layout. Confirm that the ±0.2% tolerance aligns with your system's accuracy requirements. Ensure the 1000 A maximum rating exceeds peak operational currents. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Current Sensors Selection Notes

Select this component when high-current DC measurement requires bidirectional functionality and fast response times. The 300 kHz bandwidth suits dynamic load applications better than slower sensors. Consider the base-mount form factor for thermal dissipation needs. Evaluate the 3 V to 5.5 V supply range against available system voltages before finalizing the design.

Current Sensors Part Context

This part belongs to the Riedon SSA-2 series of analog current sensors manufactured by Bourns. The series provides resilient connectors and compact modules for industrial applications. The SSA-2-1000A specifically targets the upper end of the 100 A to 1000 A measurement range within this family.

Current Sensors Replacement Considerations

The predecessor model SSA-1000 is obsolete. Verify mechanical compatibility between the older SSA-1000 and the new SSA-2-1000A due to potential connector or dimensional differences.
