CQ209A

Current transducers are devices used to measure and monitor electrical current. The CQ209A is a current transducer used to measure and monitor the DC current of low voltage power systems. This device can measure an input current of up to 100A DC and is suitable for use in building automation, energy monitoring, and process control applications.

The CQ209A current transducer consists of three main components: a current transformer (CT) , voltage reference and amplifier. A current transformer (CT) is used to convert the measured current into an AC signal, which is then fed into the voltage reference and amplifier components. The voltage reference and amplifier then convert the AC signal into an output voltage signal. This signal is then used to monitor the DC current without the need for any extra hardware.

The CQ209A current transducer has an application field in the low voltage power system environment. This device can measure the current on one or more DC power sources that are within the range of 0 to 100A. The device is equipped with a LED display to show the measured current value and is capable of accurately monitoring the DC current up to a resolution of 1mA. It also has a variety of output interfaces including RS485 and RS232.

In addition, the CQ209A current transducer is equipped with an onboard microprocessor which can be programmed to provide various functions such as signal smoothing, voltage and temperature monitoring. The device also has over current, over voltage and over temperature protection functions to ensure safety and reliability. The CQ209A current transducer can also be used in applications that require an isolated signal output.

In operation, the CQ209A current transducer works by measuring the current of the system under test and then converting the signal into a voltage signal. This voltage signal is then amplified and filtered before being sent as an output signal. The output signal can then be used to monitor the current without the need for any additional hardware.

The CQ209A current transducer includes a number of features to ensure its accuracy and reliability. The device is equipped with a high speed A/D converter which allows the user to measure the DC current up to a resolution of 1mA. Additionally, the device also has a LED display which allows the user to read the measurements quickly and accurately. Furthermore, the device can be programmed to perform various functions such as signal smoothing, voltage monitoring and over current protection.
