Introduction

CR4420S-100 current transducer is a device designed for the special requirements of precision and limited-space application in areas such as automotive electronics, power electronics and home electronic appliances. It has high accuracy and reliability and is suitable for continuous current measurement of DC or AC power supply and other power sources.

Working Principle

The working principle of the CR4420S-100 current transducer is simple and efficient and based on the magnetic flux, The primary circuit is the circuit whose current is to be measured. Connected to the primary circuit is a coil wound around a core of magnetic material. When the current flows through this coil, a magnetic flux is created in the core, that is proportional to the current flowing in the primary circuit. This magnetic flux is then detected by a secondary circuit, which produces an output current proportional to the value of the primary current. Hence, the magnitude of the secondary current is directly proportional to the primary current.
