1. One – sentence Description
The HLSR 10 – P is a 5V – powered, low – power consumption, high – bandwidth (400kHz) open – loop current sensor designed for the industrial and new energy fields. It supports a measurement range of ±10A, and has both an ultra – thin size and strict safety certifications.
2. Core Features
- Open – loop Fluxgate Technology: No secondary – side power supply is required, which simplifies the system design.
- Ultra – low Power Consumption: The typical power consumption is only 19mA (with a 5V power supply), which is energy – efficient.
- Extremely Thin Package: With a height of only 12mm, it is suitable for high – density PCB layout.
- Wide – temperature Stability: The operating temperature range is – 40℃~105℃, and the temperature drift coefficient is as low as ±0.075mV/℃ (typical value).
- Safety Redundancy: It has UL 508/EN 61010 certifications, a creepage distance of >8mm, and can withstand 8kV ESD electrostatic shock.
3.Core Technical Indicators
4. The Story Behind the Chip
- The HLSR 10 – P is based on LEM Group’s more than 30 years of technical accumulation in the current sensing field, and is specially developed to meet the miniaturization and high – reliability requirements of industrial automation and new energy equipment. Its core innovations are as follows:
- Patented Magnetic Core Design: Nanocrystalline alloy materials are used to balance high magnetic permeability and low loss.
- Self – developed ASIC Chip: A temperature compensation algorithm is integrated to achieve a linearity of ±0.5% (including temperature drift).
- Green Process: It complies with the RoHS standard, and the VO – grade flame – retardant shell reduces environmental pollution.
5. Design Philosophy
- Minimalism: The signal conditioning circuit is integrated on a single chip to reduce the number of peripheral components.
- Thermal Management Priority: Heat dissipation space is reserved in the PCB layout, and the thermal resistance from the junction to the environment is only 20℃/W.
- Safety – oriented: It has a double insulation design (creepage distance >8mm) and supports applications at an altitude of 3000m.
- Flexible Configuration: It supports external reference voltage input (0.5V~2.65V) to adapt to different ADC interfaces.
6. Application Scenarios
- Industrial Drives: Current loop control of servo motors and power monitoring of frequency converters.
- New Energy: MPPT tracking of photovoltaic inverters and charge – discharge management of energy storage systems.
- Power Electronics: Current sampling of charging piles and energy metering of welding equipment.
- Laboratory Instruments: High – precision electronic loads and battery testing systems.
7. Unique Advantages
- The Lowest Power Consumption in the Industry: 19mA@5V (similar products usually consume >30mA).
- Extreme Anti – interference Capability: 8kV ESD protection + 600Vrms isolation voltage.
- No Calibration Required: Temperature compensation has been completed before leaving the factory, directly replacing traditional shunt resistors.
- Ultra – thin Design: A height of 12mm saves 50% of the PCB space (compared with traditional modules).
8. What Engineers Must Know for Selection
- Range Matching Principle: Ensure that the measured current does not exceed ±10A (long – term overload may damage the magnetic core).
- Key Points of PCB Layout:
- Keep the main current path straight and away from noise sources of switching power supplies.
- Copper – clad grounding shielding in the sensitive area (pins 1 – 4).
- Use through – holes with a diameter of 1.6mm to avoid accuracy drift caused by mechanical stress.
- Temperature Compensation Formula:
(The compensation coefficient needs to be adjusted according to the actual temperature zone)
Certification Compliance: It needs to be matched with a 3000Vrms/min insulation test (UL 508 standard).
Conclusion: The HLSR 10 – P redefines the benchmark of industrial current sensors with its “small size and great performance”. Its ultra – low power consumption, high bandwidth and strict safety characteristics make it an ideal choice in the new energy and industrial automation fields. Engineers only need to pay attention to layout details and range matching to quickly implement a high – precision current detection scheme.
