LESR 15-NP

Current Transducers

Current transducers are signal conditioning elements which allow electric current from a variety of sources and applications to be easily measured and monitored. Linear Electronic Speed Regulation (LESR) 15-NP is a current transducer designed for precision current measurements in control applications. The LESR 15-NP is a non-contacting, solid-state, three phase, current transducer, with a wide range of input current capabilities. This transducer is both tamper-proof and highly accurate, with an accuracy class of 0.1 %.

LESR 15-NP Application Field and Working Principle

LESR 15-NP is designed for applications which require high precision current measurements, such as analog control loops, motor control applications, power systems monitoring, and industrial automation. The current transducer is capable of precisely measuring and monitoring currents from as low as 2A of line currents up to 400A of three-phase currents, and can be used for direct or alternating current. It is also suitable for measuring AC signals up to 600Hz, allowing it to be used in most process monitoring applications.

The transducer works by using a sensing element which induces a voltage when a current flows through it. The induced voltage is then sent to a main board via a flexible connection, which determines the magnitude of the current and sends a signal corresponding to the current measurement to the control output terminals. The main board also contains a power supply for the sensing element, and a transient suppression circuit which eliminates any spikes or surges which may occur in the signal.

The output signal of the LESR 15-NP is a voltage signal, in the form of a sine wave. The signal can be used to accurately determine the magnitude of the current flowing in the system and can be used to monitor and control the current for any given application. The signal output of the transducer is also temperature compensated to ensure accuracy in any environment.

The LESR 15-NP also includes a shunt and surge protection, as well as status and fault signals which are sent back to the main board. All errors and warnings are also reported to the main board which allows the user to take necessary action in case of errors or faults. This makes it an ideal device for use in critical applications where reliable current measurement is needed.

Conclusion

The LESR 15-NP is a reliable and highly accurate current transducer from Linear Electronic Speed Regulation (LESR). It offers wide range of input currents and is suitable for direct and alternating current measurements. The output signal of the transducer is temperature compensated allowing it to provide accurate measurements in any environment and its shunt and surge protection also ensure that the current measurements remain safe and reliable. It is an ideal device for use in critical applications where reliable current measurements are necessary.
