FRS & FL series: LEM's Open Loop Coreless Integral (OLCI) current transformers
Expanded with the new FRS and FL series LEM is expanding its portfolio of high-performance current transformers for industrial high-current applications. Both product series are based on the innovative Open Loop Coreless Integral(OLCI) technology and enable the reliable measurement of direct, alternating and pulse currents, naturally with galvanic isolation between the primary and secondary circuits.
Common features & benefits
- Bandwidth: > 1 MHz
- Delay time: < 400 ns
- Output: 4-20 mA or 0-5 V
- Supply: +12 V or +24 V DC
- Hall effect OLCI current sensor without magnetic offset
- Unipolar or bipolar measurement
- Low energy consumption & losses
- Lightweight design with M12 field connection
- Calibrated at the factory and ready for immediate use
FRS series: Compact and versatile, for currents up to 9000 A
The FRS current transformers allow precise measurements up to 9000 A and are designed with a 104 mm aperture . They are particularly suitable for applications where high bandwidth and short delay times are crucial.
FL series: For extreme currents up to 42 kA
FL current transformers are available for particularly high currents. With measuring ranges up to 42 kA and a choice of 200 mm or 300 mm aperture, they offer a solution for applications with massive conductor cross-sections and the highest power requirements.
Typical areas of application
- Wind turbines
- Power inverter
- Electrolysis applications
- High-performance drives
- Traction and trackside systems
