Honeywell Current Transformer, 12 to 18V DC Supply Voltage, +0.5% Accuracy - CSNS Series - CSNS300M

For accurate measurements in high-current applications, choose this robust current transformer from Honeywell. It uses Hall effect closed-loop technology to accurately detect currents of +600A for use in heavy-duty applications. The transformer's thermoplastic housing offers resistance to impact and serves as an insulator to prevent electric shocks and ensure safe operation. It can be mounted with busbars or installed directly onto your PCB, making it a versatile choice.

Features & Benefits

• Accuracy of ±0.5% for precise current measurements

• Broad operating temperature range of -40°C to +85°C for use in demanding settings

Applications

• Measurement and instrumentation

• Variable speed drives

• Automation industry
