Product catalog summary

Overview: This document is a technical data sheet for the Hall Effect Current Sensor model CHK_EKA5S2, produced by Cheemi Technology Co., Ltd. It provides detailed specifications, features, advantages, applications, and general data related to the sensor.

Specifications:

Electrical Data: The sensor operates at a supply voltage of +5.0VDC with a load resistance greater than 2.0KΩ. It has a rated input current (Ipn) ranging from 50A to 600A, with a measuring range of 0 to ±600A. The output voltage is specified as 2.500±2.0*(IP/IPN) V, with an accuracy of less than ±1.0% at 25°C.
Performance: The sensor has a response time of less than 3.0µs at 90% of Ipn, a bandwidth of DC-20kHz, and a power consumption of 15mA. It can accurately follow a di/dt of greater than 100 A/µs.
Environmental Conditions: Operating temperature ranges from -40°C to +85°C, and storage temperature ranges from -55°C to +125°C. The insulation voltage is 2.5KV at 50/60Hz for 1 minute AC.

Features and Advantages:

The sensor is an open-loop type with galvanic isolation between primary and secondary circuits, capable of measuring DC, AC, and pulse currents.
It offers easy installation, customization options, no insertion losses, low power consumption, a wide current measuring range, and high immunity to external interference.

Applications: The sensor is suitable for inverter applications, AC/DC variable-speed drives, uninterruptible power supplies (UPS), switched mode power supplies (SMPS), and frequency drive control in home appliances.

Standards and Materials:

The sensor complies with standards IEC60950-1:2001, EN50178:1998, and SJ20790-2000.
It is made from PBT G30/G15 plastic material, rated UL94-V0 for flammability.

Warnings and Remarks:

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