Current transducers are commonly used in electrical systems and provide real-time information on current consumption. The LF 510-S, from SUSPA GmbH, is a wide-range current transducer designed for use in industrial applications requiring precise measurement of alternating current (AC) and direct current (DC). This transducer is capable of accurately measuring AC/DC current up to 120 A and with a maximum full-scale error of ± 1 %.

The LF 510-S has a compact, rectangular design which allows for easy installation in tight spaces. It runs on 24 VDC, and it can be mounted in any orientation. The transducer also features selectable ranges provided by a single switch, allowing it to measure current up to 500 A. The transducer\'s response time is remarkably quick, measuring current in less than 1 ms.

The LF 510-S employs torque motors which create an electromagnetic force in response to current passing through the input coil. This force is proportional to the reading, and it is transferred to a gearbox to drive the output shaft. The gearbox is connected to an encoder, which measures the rotational position of the output shaft and converts it into a corresponding voltage. The voltage is then sent to the relevant measuring instrument.

The LF 510-S supports two output options: analog and binary format (Bus-CAN). The analog output is a DC voltage signal and it has a resolution of 12 bit, allowing for detailed measurements within a range of 0 – 10 V. Additionally, the transducer has an over-voltage protection feature which prevents it from getting damaged in the event of a power surge. The transducer\'s binary output is a CANBus signal with 8 different commands, which can be used to control the digital device it is connected to.

The LF 510-S also includes several useful safety features. It has pressure-resistant housings, which protect it from sudden changes in the environment, and has an integrated insulation monitor, which constantly monitors the insulation level of the transducer against ground. This reduces risks associated with electric shocks in the event of a power surge or contact with the transducer.

The LF 510-S is a reliable and accurate current transducer which is ideal for industrial applications requiring precise and real-time measurement of alternating and direct currents. It has a compact design and a fast response time, and its output options allow for detailed measurements and control. Moreover, its safety features reduce the chance of damage to the transducer and electric shocks.
