## **Product Datasheet**
The LKSR Series current sensors are engineered for applications requiring enhanced insulation performance and precise measurement of low to medium DC, AC, and pulsed currents. With nominal current ranges up to 75A, LKSR parts combine closedloop Halleffect sensing with a distinct 4pin primary footprint.
This mechanical design increases creepage and clearance distances up to 9.9 mm, making the LKSR Series particularly suitable for designs with reinforced insulation requirements. In addition, reference voltage access enables flexible signal adaptation.
The LKSR Series operates reliably across a wide temperature range, ensuring stable performance in demanding industrial environments.
## **Main characteristics**
- Closed loop multi-range current transducer
- Voltage output
- Unipolar supply voltage
- Compact design for PCB mounting
- Cost attractive
- PCB mounting in various footprints (3 or 4 primary pins with various layouts)
- With integrated primary conductors
- Compact design
- High overall accuracy at +105°C up to 2%
## **Benefits**
- Very low offset drift
- Very good dv/dt immunity
- Fast response time <0.4 µs
- CKSR footprint compatible
- Reference pin with two modes: Ref IN and Ref OUT
- Extended measuring range for unipolar measurement
## **Typical applications**
LKSR products are made for industrial use and serve various functions:
- AC variable speed and servo motor drives
- Static converters for DC motor drives
- Battery supplied applications
- Uninterruptible Power Supplies (UPS)
- Switched Mode Power Supplies (SMPS)
- Power supplies for welding applications
- Solar inverters
