LZSR 200-P/SP1

Current Sensors Overview

The LZSR 200-P/SP1 is a closed-loop Hall effect current transducer designed for precise measurement of DC, AC, and pulsed currents. It features a primary rated current of 200A and operates on a single +5V power supply (4.75V to 5.25V). The device provides an analog output signal at 2.5V. It utilizes a PCB mount configuration with a through-hole design for the primary conductor insertion. The sensor ensures galvanic isolation between the primary circuit and secondary electronics.

Current Sensors Feature Summary

• Closed-loop Hall effect technology for high-precision current sensing
• Single +5V power supply operation simplifying integration
• Analog voltage output signal for direct interface with control systems
• Through-hole PCB mounting for primary conductor insertion

Current Sensors Applications

• Solar energy system current monitoring
• Industrial power supply current regulation
• Battery management systems requiring isolated sensing
• Motor drive applications with pulse current measurement

Current Sensors Procurement Notes

Verify the specific suffix SP1 against the manufacturer's latest datasheet to confirm pinout compatibility and mechanical dimensions. Ensure the application environment remains within the specified operating temperature range. Confirm that the required peak current does not exceed the sensor's saturation limits defined in the official electrical characteristics table.

Current Sensors Selection Notes

Select this component when a single-supply +5V solution is required for isolated current measurement up to 200A RMS. The through-hole design accommodates external busbars or wires, offering flexibility in primary conductor sizing compared to integrated versions. Consider the analog output level for ADC compatibility in the target microcontroller or PLC system.

Current Sensors Part Context

The LZSR series expands LEM's portfolio of single-supply current sensors, extending the measurement range up to 450Apk. This series utilizes Hall effect ASICs to achieve low offset drift and improved performance over previous generations. The -P variant specifically denotes the open-hole design for custom primary conductors, distinguishing it from integrated conductor models.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other LEM series such as LFxx10 or HTFS only if electrical parameters and mounting styles match exactly.
