LF 210, 310, 510, 1010, 2010 Family
For DC, AC, pulse currents' measurements of 100 to 2000 ARMS nominal with galvanic isolation
LF 210, 310, 510, 1010, 2010 - Current Sensors
The LF 210, 310, 510, 1010, and 2010 current sensor series has been meticulously designed to cater to both industrial and railway applications. These sensors are optimized for the precise measurement of DC, AC, and pulsed currents while ensuring galvanic isolation between the primary circuit and the secondary circuit.
The LF electronic parts are known for their compact design and provide excellent accuracy, rivaling Fluxgate technology but at a more cost-effective price point. Additionally, they ensure fast response times, with a response time of less than 0.5 µs.
These sensors can be panel-mounted in various configurations, making them adaptable to different system setups.
The five product series within this range feature different aperture diameters for the primary conductor crossing. LF 210 has a 15.59 mm diameter aperture, LF 310 offers a 20 mm diameter aperture, LF 510 provides a choice between a 30 x 10 mm or 30 mm diameter aperture, LF 1010 offers a 40 x 13 mm or 38 mm diameter aperture, and LF 2010 presents a 60 x 20 mm or 57 mm diameter aperture.
These current sensors rely on closed-loop Hall effect technology, which enhances their accuracy and reliability in industrial and railway applications, making them well-suited for a variety of contexts where precise current measurements are crucial.
