Product catalog summary

Overview: This document is a technical data sheet for the Hall Effect Current Sensor, model CHK_LSP3S1L, produced by Cheemi Technology Co., Ltd. It provides detailed specifications, features, advantages, applications, and general data for the sensor.

Specifications:

Electrical Data: The sensor operates at a supply voltage of +3.3 to +5.0 VDC with a rated input current (Ipn) ranging from 15A to 30A. The measuring range corresponds to the rated input, and the output voltage is specified as 1.650±1.250*(IP/IPN) V.
Accuracy: The accuracy at Ipn and 25°C is less than ±1.0%, with an offset voltage of less than ±20 mV at IP=0 and 25°C.
Temperature Variation: The offset voltage variation is less than ±0.1 mV/°C, and the output voltage variation is less than ±0.4 mV/°C over a temperature range of -40 to +85°C.
Performance: The sensor has a linearity error of less than 1.0% FS, a response time of less than 3.0 µs at 90% of Ipn, and can accurately follow di/dt greater than 50 A/µs.

Features:

Open-loop design with galvanic isolation between primary and secondary circuits.
Capable of measuring DC, AC, and pulse currents.
High accuracy, very good linearity, low temperature drift, and low power consumption.
Optimized response time with no insertion losses and high immunity to external interference.

Applications: The sensor is suitable for photovoltaic (PV) current applications, AC/DC variable-speed drives, uninterruptible power supplies (UPS), switched mode power supplies (SMPS), and inverter applications.

General Data:

Operating temperature range: -40 to +85°C.
Storage temperature range: -55 to +125°C.
Mass: 10g.
Plastic material: PBT G30/G15, UL94-V0.
Standards: Complies with IEC60950-1:2001, EN50178:1998, and SJ20790-2000.

Warnings and Remarks:

Incorrect wiring may cause damage to the sensor.
Custom designs are available for different rated input currents and output voltages.
The primary conductor should not exceed 100°C.
