The LDS803-51 is a high-correlation dual-sensing Hall-effect current sensor manufactured by Gentech. It is designed to provide a reliable and repeatable measure of AC and DC current in motor control and power systems, with the ability to sense currents up to 100A. Its small size and easy-to-handle packages make it ideal for applications in a variety of applications, including motor control, power converters, power electronics, charging systems, and inverters. The device features a temperature-compensated two-range DC current sensing and over-current protection, as well as an integrated quartz oscillator to help improve accuracy. Additionally, it features an adjustable output, low common-mode voltage, and low frequency response.
