SCN1 Series CAN BUS current sensor 100A, 300A, 500A, CAN BUS output signal

Product catalog summary

Overview
The SCN1 Series by Shenzhen SoCan Technologies Co., Ltd is a CAN bus-based Hall current sensor designed for high accuracy and stable performance. It is compact and ideal for current measurement and control in electric vehicles and transportation, utilizing the CAN protocol 2.0 A for digital output.

Working Principle
The sensor operates on the Hall effect principle, converting current signals into digital outputs.

Main Parameters
The SCN1 series includes models with primary current ratings of 100A, 200A, 300A, 400A, and 500A. The output signal follows the CAN2.0-A standard frame format.

Performance Parameters
Key performance metrics include a working voltage range of 9-30 VDC, current consumption of 19-36 mA, and a resolution of 0.1 A. The sensor maintains accuracy within ±1.5% and linearity within ±1.0% at 25°C.

Pin Description and Application
The sensor has four pins: +12V DC power supply, ground, CANH, and CANL.

Communication Protocol Technical Requirements
The sensor outputs a digital CAN signal and requires a single power supply compatible with 9V-30V. It supports a bus baud rate of 250K bps and uses the CAN2.0A extended frame format.

Sensor Installation
Installation can be vertical or flat, with wiring circuits positioned for optimal accuracy.

Precautions
Ensure concentric alignment of the conductor and sensor window, connect working power before use, and use shielded wires to avoid interference. The temperature of the input current should not exceed 80°C.

Maintenance
Avoid deformation, heavy objects, and heat sources near the sensor. In corrosive environments, seal joints and bolts to prevent damage.

Package
The sensor is packaged in a carton box.
