Current Sensors Procurement Notes

Verify the specific suffix BP10 to confirm the bipolar voltage output configuration, as other suffixes such as MA or SE indicate different output types like 4-20mA or single-ended signals. Ensure the required current rating aligns with the 1000A specification, as the series offers multiple ranges including 500A, 2000A, and higher capacities. Confirm that the 77mm aperture dimension matches the conductor size for proper clamp engagement and measurement accuracy.

Current Sensors Selection Notes

Select this model when a bipolar voltage output ranging from 0.0V to ±10V is required for integration with data acquisition systems. The 1000A rating distinguishes it from lower-capacity variants like the CPCO-500-77-BP10. Consider the 10µs response time for applications requiring fast transient capture. Verify that the operating temperature range of -40°C to 100°C meets environmental requirements, and ensure the 11V to 31V supply voltage compatibility with the host system.

Current Sensors Part Context

This component belongs to the CPCO Series of DC-AC current probes from GMW Associates. The series includes various models differentiated by current ratings (500A, 1000A, 2000A, etc.) and output configurations. The CPCO-1000-77-BP10 specifically utilizes the 77mm aperture design, which is standard for handling larger conductors compared to smaller aperture options. The BP10 suffix denotes the specific bipolar output variant within this product family.

Current Sensors Replacement Considerations

Direct substitutes include other CPCO-1000-77 variants with matching output specifications. Models such as CPCO-1000-77-MA offer 4-20mA output instead of voltage, while CPCO-1000-77-SE provides single-ended output. Ensure any replacement maintains the 1000A rating, 77mm aperture, and compatible supply voltage range to preserve system functionality.
