1. High Accuracy & Real-Time Response
Wide current range – 32A nominal, ±80A measurement range. Easily handles overcurrent and pulsed current monitoring.
High accuracy – Linearity ±0.5%, overall accuracy ±1%. At +25°C, measurement accuracy reaches ±1%; even at an operating temperature of up to 105°C, accuracy stays within ±3.4% – delivering reliable data around the clock.
Ultra-fast capture – Response time only 2.5µs. The high dynamic response ensures precise capture of sudden current changes such as inverter start-up transients or power supply spikes.
2. Compact & Space-Saving
Minimal footprint – Through-hole PCB mounting, height only 12mm, PCB footprint just 387mm². The slim profile allows flexible placement on spaceconstrained boards.
Low power consumption – Maximum supply current only 25mA, reducing overall system energy dissipation and heat generation.
3. High Isolation & Reliable Operation
High dielectric strength – 4.3kVrms (50Hz, 1min) isolation between primary and secondary circuits, ensuring operator and downstream circuitry safety.
Wide temperature range – Operating from -40°C to +105°C, stable performance under harsh conditions.
4. Flexible & Easy Integration
Single +5V supply – Supports 4.5V to 5.5V wide input voltage, compatible with most existing system power solutions.
Bidirectional measurement – Measures AC/DC bidirectional current. Output is a ratiometric voltage with a fixed sensitivity of 25mV/A. A dedicated reference voltage pin simplifies direct connection to an ADC.
Industrial drives & servo systems – Accurately capture transient current changes in motor drives for precise closedloop control.
Switching power supplies & UPS – Monitor input/output current in real time, helping achieve high efficiency and safe operation.
Renewable energy systems – Use in solar combiner boxes and inverter MPPT tracking for accurate power calculation.
Home appliances & special power supplies – Suited for variablefrequency air conditioners, welding equipment, and other high-power applications.
With ±1% high accuracy, 2.5µs ultra-fast response, 12mm slim height, and 4.3kVrms strong isolation, the LEM HLSR32-P outperforms traditional shunt resistors and optocoupler-based solutions. Choosing the HLSR32-P means selecting not just a reliable current sensor, but also LEM’s 50 years of technological expertise and global quality commitment.
