LEM electronics released a new low-cost current sensor

the new hlsr sensor has five models, with current measurement up to 50a, which can meet a variety of application needs, such as industrial frequency converter, motor drive, switching power supply and uninterruptible power supply, special power supply such as welding unit, air conditioning, household appliances, and new energy systems, such as solar combiner box and maximum power point tracking (MPPT) in solar inverter

Lyme's hlsr series sensors use open-loop hall principle current measurement technology to measure AC, DC or pulse current. It is expected to reach 2019, with a rated value of 10, 20, 32, 40 or 50arms. Lyme's professional and reliable open-loop hall technology has achieved a response time of only 2.5 seconds for this new sensor, as well as low zero and gain drift in the operating temperature range of -40 to 105 C

hlsr sensor provides analog voltage output proportional to primary side current. In many applications, the voltage is converted to a digital value by an analog-to-digital converter. Lyme hlsr can set the internal reference signal amplification voltage of this chipset to 1.65 or 2.5V, and provide special pins to connect external devices, such as a/d converter. The designer can choose to use the external reference value of 0.5 to 2.65v. The voltage reference value is a major feature of the latest ASIC technology. The designers of LEM products apply it to the products, so that the hlsr series accuracy can reach 1% at 25 C, 3.4% at 105 C, and the bandwidth is 100kHz (-3db). Lyme offers two models of 3.3V or 5V single voltage power supply

the five models of Lyme hlsr series use unified package and shell design. The innovative appearance only occupies 387mm2 of PCB, smaller than the resistance parallel scheme

the parameters of the package meet both the surface mounting and the perforation mounting mode, and can be connected to the primary conductor, signal and power supply. The product is only 5.5G in weight and less than 12mm in height

the high isolation between the primary side and the measuring circuit ensures the safety of measurement. It has a long creepage distance and electrical clearance (the standard model is 8mm, which can be adjusted to 14mm according to the customer's requirements). Cti600hlsr has passed CE certification, complies with the en50178 standard required by the industry to be responsible for the faults caused by the defects of design, manufacturing, process or materials, and provides a five-year warranty
