Product Description
The LEM HAT 400-S is a specialist current transformer engineered for precise measurement of high currents up to 400 A, suitable for both AC and DC applications as well as mixed-current environments. Built around advanced Hall Effect technology and a proprietary ASIC, this model offers reliable performance and low power consumption for incorporation into process control, automation, and power distribution systems.
Operating from a stable 15V supply voltage, the HAT 400-S supports wide-ranging installation flexibility thanks to its busbar and plug-in mounting options. Its robust design, featuring a 15mm bore diameter and 37mm depth, allows easy integration in compact enclosures or tight space requirements, while maintaining a wide -40°C to 105°C operating temperature range to withstand demanding industrial conditions.
Key technical features include ratiometric output (Vcc/2 reference), unipolar supply architecture, and an extremely low-profile build. This transformer is optimized for applications requiring rapid response and significant current ranges, from power distribution panels to advanced process control systems. The HAT series also offers secure fixing via four holes (P version) and mounting via four solder pins (P/SP2 version), facilitating straightforward PCB or panel installation.
Compliance with JEDEC JESD46-B standards ensures high reliability, and its low power draw makes it a preferred choice for energy-efficient systems. Compact yet robust, this product is ideal for industrial automation, manufacturing, laboratory measurement, commercial power management, and process monitoring scenarios where precision current sensing is critical.
Industrial use cases cover electrical panels, automation control gear, process control, energy meters, and power quality monitoring. Its hall sensor-based design assures accuracy and stability for both AC and DC current metering in modern electrical installations.
