Power Supply

Power Supply

Power supply based applications using devices made up of power electronics (chargers, DC links, batteries, inverters and/or rectifiers) all require efficient current control, monitoring, regulation and protection.

This is necessary to ensure their integrity and normal functioning.
J&D transducers ensure: stable power supply accurate currents conversions depending on the various stages timely information in case of corrections or potential switching quick reactions in the event of emergency and failure.

Transducers are paramount to an efficient and operational grid.


In many applications, the voltage from the grid is too high or has to be converted to DC voltage or to a different AC waveform.
It is therefore transformed by modern power electronics.
A transducer measures the output current to ensure stable power supply.


Power supply is critical for the effective function of applications such as cell phones base stations or hospitals security systems who must always remain operational.

In case of failure (short circuit, unexpected connection to earth, etc.) or fault in the grid interrupting the power, batteries or Uninterruptible Power Supplies (UPS) temporarily provide emergency power.

Transducers are used to control the charge and discharge of these batteries as well as the switch to the batteries and UPS.

Why Current Transducers are required for Power Supply

Stability and Sustainability are important keywords for equipment that needs power supply. For reliable and continuous operation of power supplies and drive systems, solutions for monitoring and controlling power quality are required. The role of the Current Transducers is one of the important ways the solution can be successfully realized, as the above factors are dictated by how accurate and reliable the CT is delivering the signal. This makes the equipment operate efficiently.

1. Stability

Many equipment, such as automation systems in industrial complex production plants, are sensitive to unexpected voltage fluctuations and power supply declines such as overcurrent, instantaneous voltage drop, and instantaneous peak. When power sourcing in the Generating system itself, errors occur, and it can be transferred to the distributed system as it is. This has dangerous factors that can lead to plant closures and loss of production. J&D Current Transducers can secure the reliability of the supply power by detecting these abnormal signals in real time through accurate and appropriate output verification.

2. Continuity

Devices that prepare for hazardous situations (e.g., hospital equipment) may pose risks if they do not receive continuous power. To prevent such risks, it is important to continuously check the power quality. Power quality needs to be continuously measured and analyzed so that unexpected hazards can be detected early.

J&D Current Transducers detect these degraded signals and increase the reliability of the supplied power. In addition, the JAGUAR IoT solution allows you to check power quality in real time.
