1000A High-Precision Hall Effect Current Sensor HAT1000-S – The Reliable Choice for High-Current Industrial Measurement

In modern industrial automation and energy management systems, the accuracy, response speed, and reliability of current measurement directly impact the operational efficiency and safety of the entire system. As a global leader in current sensing technology, LEM offers the HAT series – widely recognized for its outstanding performance and compact design. The HAT1000-S, a flagship model in this series, is specifically designed for high-current measurement up to 1000A. It is the ideal solution for motor drives, power supplies, renewable energy systems, and industrial automation.

HAT1000-S Superior Performance – Meets Demanding Measurement Needs

Based on mature openloop Hall effect technology, the HAT1000-S accurately measures DC, AC, and pulsed currents. Its rated primary current is 1000A, with a measurement range extending up to ±2500A – three times the rated value – perfectly covering everything from normal loads to overload conditions.

In terms of accuracy and stability, the HAT1000-S delivers exceptional performance: linearity and overall accuracy reach ±1% , providing reliable data for closedloop control, energy metering, and other precisioncritical applications. Furthermore, the sensor offers a wide frequency response from DC to 25kHz combined with a fast response time of 5µs , enabling accurate capture of dynamic current changes – ideal for variable frequency drives, switching power supplies, and other highfrequency monitoring scenarios.

HAT1000-S Wide Temperature Range – Adapts to Harsh Industrial Environments

Industrial environments are often demanding, requiring equipment to withstand extreme conditions. The HAT1000-S operates over a wide temperature range from -40°C to +105°C , ensuring stable and reliable measurement whether installed in outdoor equipment in freezing climates or in enclosed cabinets in high-temperature settings. Under normal room conditions, its storage temperature range extends from -25°C to +85°C, providing ample margin for warehousing and transport.

HAT1000-S Safe Isolation & Low Power – Simplifies System Design

Electrical safety is a top priority in industrial system design. The HAT1000-S offers up to 3000V galvanic isolation between the primary and secondary circuits, effectively separating the main power circuit from the signal control circuit. This not only protects operators and downstream electronics but also greatly enhances system immunity to interference. In terms of power consumption, the sensor draws only 15mA maximum from a ±15V bipolar supply. Its low-power design makes it especially suitable for long-duration continuous operation and systems where power budget is a concern.

HAT1000-S Compact Design – Easy to Install and Integrate

The HAT1000-S features a modular package with base mounting. Its compact dimensions minimize space occupation, facilitating system integration and mass production. The housing is made of UL 94-V0 rated insulating plastic , offering excellent flame retardancy and mechanical strength, fully complying with safety standards for industrial equipment.

HAT1000-S Typical Applications

With its outstanding performance and environmental adaptability, the HAT1000-S is widely used in:

Motor drives & control – current monitoring and closed-loop control in AC/DC variable frequency drives

Power supplies – current sensing and fault detection in SMPS, UPS

Renewable energy – high-current management in solar inverters, wind turbine converters, energy storage systems

Battery management systems (BMS) – high-current charge/discharge monitoring for EVs and energy storage batteries

Welding equipment – real-time load current monitoring for welding power sources

HAT1000-S Quality Assurance & Compliance

The HAT1000-S is manufactured by LEM USA Inc. with an active product status, ensuring reliable long-term availability. It complies with RoHS directives – lead-free design meets green manufacturing requirements, allowing customers to choose high-performance products while supporting sustainable development.

Why Choose the HAT1000-S?

Whether you are a power supply system engineer, an automation equipment integrator, or a supplier for renewable energy projects, the HAT1000-S will become the reliable cornerstone and quality guarantee of your current measurement solution – with high accuracy, fast response, strong isolation, and low power consumption.
