WCS1702 2~5 Amp Hall Effect Current Sensor Module

Introduction

The Winson WCS1702 provides economical and precise solution for both DC and AC current sensing in industrial, commercial and communications systems. The unique package allows for easy implementation by the customer. Typical applications include motor control, load detection and management,over-current fault detection and any intelligent power management system.

The WCS1702 consists of a precise, low-temperature drift linear hall sensor IC with temperature compensation circuit and a current transformer with 0.24 μΩ typical internal conductor resistance. This extremely low resistance can effectively reduce power loss, operating temperature and increase the reliability greatly. Applied current flowing through this conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage.
