Socan Open loop current sensor SCK19D Series

Product catalog summary

Product Description:
The SCK19 Hall Effect Current Sensor by Shenzhen SoCan Technologies Co., Ltd. is designed based on the Hall effect measurement principle and operates in an open loop circuit mode. It features a high isolation voltage of over 3000VAC between primary and secondary circuits, compact size, and compliance with the UL94-V0 flame retardant rating. The sensor uses a single-chip programmable Hall IC.

Performance:
The sensor can measure DC, AC, pulse, and various irregular waveforms under isolated conditions. It operates at a +5V working voltage, offering fast response speed, low zero drift, low temperature drift, high accuracy, and good linearity. Optimal dynamic performance is achieved when the busbar is fully filled with primary perforations. It also has strong resistance to external electromagnetic interference.

Applications:
The SCK19 sensor is suitable for use in photovoltaic inverters, electric vehicle drivers, battery management systems, and other related products.

Implementation Standards:
The sensor adheres to several standards, including GB/T 7665-2005, JB/T 7490-2007, JB/T 25480-2010, JB/T 9473-2020, and SJ 20792-2000.

Technical Parameters:

Input power supply voltage range: +4.5 to +5.5 VDC
Current consumption: up to 15 mA
Output voltage: 2.5V ±1V to 2.5V ±2V depending on the model
Accuracy: ±1% at IPN, TA=25°C
Linearity: ±0.5% IPN at RL=10KΩ, TA=25°C
Response time: 3 to 5 µs
Operating temperature range: -40°C to 125°C

Model Variants:
The SCK19 sensor is available in various models with primary current ratings ranging from 3A to 70A, with corresponding peak values and output voltages.

Notes:

Ensure VC accuracy to maintain measurement precision.
Primary conductor temperature should not exceed 105°C.
Incorrect wiring may damage the sensor.
