Hall Effect Current Sensor

Product catalog summary

Overview: This document is a technical data sheet for the Hall Effect Current Sensor, model CHK_LB5S2, 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 +5.0VDC with a rated input current (Ipn) ranging from 50A to 300A, depending on the model. It has a measuring range of 0 to ±300A and an output voltage of 2.500±2.000*(IP/IPN) V. The accuracy is less than ±1.0% at 25°C, with an offset voltage of less than ±30mV.
Performance: The sensor has a response time of less than 3.0µs at 90% of Ipn, a bandwidth of DC-20kHz, and can accurately follow a di/dt of over 100 A/µs. It consumes 15mA of power and has an insulation voltage of 2.5kV.

Features:

Open-loop design with galvanic isolation between primary and secondary circuits.
Excellent accuracy and linearity, easy installation, customizable, optimized response time, and high immunity to external interference.

Applications: Suitable for photovoltaic 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°C to +85°C.
Storage temperature range: -55°C to +125°C.
Mass: 25g.
Plastic material: PBT G30/G15, UL94-V0.
Standards: IEC60950-1:2001, EN50178:1998, SJ20790-2000.

Dimensions and Connection: The sensor has specific dimensions and connection requirements, including a primary through-hole of D16.0±0.15mm and a secondary connection of 5pin 0.635*0.635mm. General tolerance is less than ±0.5mm.

Remarks: Custom designs are available for different rated input currents and output voltages. The best dynamic performance is achieved when the primary hole is fully filled. The primary conductor should not exceed 100°C. Incorrect wiring may damage the sensor.
