LAH50-P Frequently Asked Questions (FAQs)

  • LEM recommends a symmetrical PCB layout with a ground plane underneath the device to minimize electromagnetic interference. A minimum of 2mm clearance around the device is also recommended to ensure proper heat dissipation.
  • To ensure accurate current measurement, it's essential to follow the recommended wiring and connection guidelines. Use twisted pair wires for the current sensing lines, and keep them as short as possible to minimize noise and interference. Also, ensure that the burden resistor is correctly sized for the application.
  • The LAH50-P can operate within a temperature range of -40°C to 125°C. However, it's recommended to derate the device's performance at temperatures above 85°C to ensure reliable operation.
  • Yes, the LAH50-P is designed to withstand high-vibration environments. However, it's recommended to follow proper mounting and soldering techniques to ensure the device remains securely attached to the PCB. Additionally, consider using a vibration-resistant PCB material and design.
  • Calibration of the LAH50-P involves adjusting the zero-point and gain settings. Follow the calibration procedure outlined in the datasheet, and use a high-precision current source and multimeter to ensure accurate measurements.
