What is the function of a current transducer with dc output?

1. Introduction

The current transducer uses the principle of electromagnetic induction to measure the AC current in the power grid in real time, and uses precision constant current technology and linear temperature compensation technology to isolate and convert it into a standard DC signal output. It uses 24V or 12V safe voltage power supply, has the characteristics of strong overload capacity, high precision, high isolation, high safety, low power consumption, etc., and can be widely used in the field of industrial automation.

2. BA series Current Transducer

BA series AC current transducer is an instrument that can convert the measured AC current into a linear proportional DC voltage or DC current output. It is widely used in electrical devices, automatic control and dispatching systems in various industrial automation systems, power, post and telecommunications, petroleum, coal, metallurgy, railways, municipal and other departments.

3. Product selection

Application

1. The output is connected to the reverse display meter to display the current;

2. The output is connected to the PLC, then to the servo controller, and then controls the motor to achieve the corresponding control result.

How to choose:

1. Select the aperture size according to the current cable.

2. Select the range according to the input current range, generally leaving a 1/3 margin.

3. Determine the output signal and auxiliary power supply.
