LF510-S Description

Short technical summary and product information.

The LEM LF510-S is a panel-mounting, closed-loop current transducer engineered for precise electronic measurement of DC, AC, and pulsed currents. It offers galvanic separation between the primary and secondary circuits, ensuring safety and signal integrity.

 

Key electrical specifications include a maximum supply voltage of ±25.2V and a nominal primary current rating of 500A. The device operates within an ambient temperature range of -40 to 85°C, with a maximum primary conductor temperature of 100°C. It features a secondary current output of 0 to 186mA with a secondary supply voltage of 0 to ±24V DC.

 

This transducer is suitable for applications requiring high accuracy and very low offset drift over temperature. Its design includes a shield between the primary and secondary for enhanced performance. The connection to the secondary circuit is made via a shielded cable.

 

Applications for the LF510-S include single or three-phase inverters, propulsion and braking choppers, propulsion converters, auxiliary converters, battery chargers, and substations. It is compliant with various standards including EN 50155, EN 50124-1, EN 50121-3-2, IEC 62497-1, IEC 61010-1, IEC 61800-2, and UL 508.
