Overview
The LA 55-P/SP1 is a closed-loop Hall effect current transducer designed for the precise electronic measurement of DC, AC, and pulsed currents with galvanic isolation. It operates as a current-compensated device, providing high accuracy of 0.65 percent and a wide bandwidth of 200 kHz for high-speed power electronics monitoring.
Why Choose This Part
The closed-loop architecture ensures excellent linearity and low temperature drift across the -40C to +85C operating range. Its high bandwidth of 200 kHz allows for accurate tracking of fast-switching transients in modern SMPS and motor drive topologies.
Applications
Key Specifications
Getting Started
To integrate this sensor, provide a bipolar power supply between +/-12V and +/-15V and select a suitable measuring resistor (Rm) to convert the secondary output current into a voltage for your ADC. Ensure the PCB layout maintains creepage and clearance distances required for high-voltage isolation between the primary busbar and the three-pin secondary interface.
