CPCO-1000-77-SE

Current Sensors Overview

The CPCO-1000-77-SE is a DC-AC current probe manufactured by GMW Associates. It features an open-loop Hall-effect design with a single-ended output configuration. The sensor supports bidirectional current measurement up to ±1kA through a 77mm aperture. Electrical specifications include a supply voltage range of 11V to 31V and a maximum supply current of 47mA. The device provides a ratiometric output signal ranging from 5.0V±5.0V, corresponding to the measured current. It exhibits a response time of 10µs and operates within a frequency range of DC to 40kHz. The unit is housed in a box package and functions reliably across an operating temperature range of -40°C to 100°C.

Current Sensors Feature Summary

• Open-loop Hall-effect sensing technology for accurate DC-AC current measurement
• Bidirectional polarization enabling detection of both positive and negative current flows
• Single-ended output providing a ratiometric voltage signal proportional to current
• Wide aperture size accommodating large conductors without disconnection

Current Sensors Applications

• High-current power supply testing and characterization
• Electric vehicle battery management system monitoring
• Industrial motor drive analysis and fault detection
• Renewable energy inverter performance verification

Current Sensors Procurement Notes

Verify that the specific suffix SE denotes the single-ended 5.0V±5.0V output variant rather than other output configurations like MA or BP10. Confirm aperture compatibility with conductor dimensions prior to installation. Ensure supply voltage remains within the 11V to 31V range to maintain specified accuracy and operational integrity under all environmental conditions.

Current Sensors Selection Notes

Choose this model when high current capacity up to 1000A is required alongside precise bidirectional tracking. The 77mm aperture suits larger cables where non-invasive measurement is critical. Single-ended output simplifies interface with data acquisition systems requiring direct voltage input. Consider thermal limits if ambient temperatures approach the upper specification boundary during continuous operation.

Current Sensors Part Context

This component belongs to the CPCO series of clamp-on current probes from GMW Associates. The series utilizes open-loop Hall-effect sensors for robust industrial applications. Variants differ primarily in output type and packaging. The CPCO-1000-77-SE specifically addresses high-current measurement needs with a standardized single-ended voltage output format compatible with common instrumentation.

Current Sensors Replacement Considerations

Direct substitutes include CPCO-1000-77-BP10 and CPCO-1000-77-MA. Note that these variants offer different output signals such as 4mA-20mA or alternative voltage ranges. Verify interface compatibility before substitution as output characteristics significantly impact system integration requirements.
