3. Product Applications - High Current Transducers

High current current transducer applications can measure high DC & AC current . These transducers generate a signal whose magnitude is proportional to the current being measured; this signal can be transmitted with forms of voltage,  current and RS485. It’s important to note that high current DC current transducers are useful in many contexts, including:

In electric vehicles (EVs), high current DC current transducers track the charging and discharging of batteries, as well as the operation of motors and the distribution of electricity.

High current transducers are used to monitor power generation, conversion, and distribution in renewable energy systems like solar power plants, wind farms, and others.

High current transducers are used in power electronics to measure and regulate high currents in high-voltage power transmission systems, including power converters and inverters.

These transducers are used in welding, motor control, power supplies, and robotics among other industrial applications to measure and regulate high currents for the purpose of ensuring the security and efficacy of these processes.

High current DC current transducers are used in smart grids, energy storage systems, and facility management to track and optimise power usage for maximum efficiency and savings.

Overcurrent conditions in high current circuits can be detected by transducers, allowing protective measures to be taken to prevent equipment failure.

In the telecommunications industry, high current transducers can be used to keep data centres and other network nodes running smoothly and reliably by monitoring and controlling the flow of power.

High current transducers are used to monitor and manage power distribution in railway systems and other electric transportation systems to guarantee safe and efficient operations.

High current transducers are a type of test and measurement equipment that is used in a wide variety of R&D settings to measure and analyse high current levels in different types of electrical systems and devices.

In large-scale battery systems, like those used for grid energy storage or backup power systems, high current transducers are used to monitor charging, discharging, and overall health.

As you can see, the uses for high current DC current transducers are practically endless. As a result of their ability to precisely monitor and record high current levels, they are indispensable to many sectors and systems that depend on streamlined power distribution and management.
