Current transducers are essential devices in electrical engineering. They provide a wide range of applications from indicating which components are in operation, to measuring current flow and its direction safely and accurately.

The CR5220-30 is a digital current transducer widely used within the engineering sector. It has been designed for performing current sensing requests in harsh and potentially hazardous conditions. With the ability to withstand high temperatures, it is an ideal choice for applications such as emergency lighting UPS systems and environmental protection regulation.

The CR5220-30 can sample currents up to 100Amps and provides both an alarm and disconnect relay output. It is used primarily as a protection device for electrical systems. It can be installed inside panels or as a stand-alone unit on a machine or vehicle, providing an indication of an abnormal temperature, current or voltage within the circuit.

The working principle of the CR5220-30 is based on Faraday’s Law of Induction. A voltage is induced in a current sensing coil which is fixed securely inside the device. This voltage is proportional to the instantaneous current flowing through the coil and is then conditioned and amplified by a circuitry. This amplified signal is then converted into a digital signal which is output in the form of an alarm and disconnect relay. The signals can then be monitored and analyzed for further engineering use.

The CR5220-30 can be easily configured by a range of parameters depending on user needs. This includes alarm levels, disconnect levels and time delay levels. Settings can be easily modified online or through a programmable microcontroller. This provides users with an accurate and reliable device for current sensing applications.

In short, the CR5220-30 is a reliable and robust digital current transducer that is suitable for any engineering application. It is easy to configure and offers a variety of alarm and disconnect levels for different current thresholds. Through its Faraday’s Law of Induction principle, it provides users with an accurate indication of current flow and its direction.
