ACREL AKH-0.66 SM-200ii Dual Winding Current Transformer

The ACREL AKH-0.66 SM-200ii Dual Winding Current Transformer is part of the AKH-0.66/SM dual-output current transformer series. The series is designed to provide two independent outputs from one current transformer, allowing conventional AC current measurement and industrial automation signal transmission from the same installation.

For the SM-200II model, the manufacturer specifies primary current ratios from 2000 A to 6300 A, with the available ratio determining the applicable accuracy and rated burden. The transformer is designed around a 200 mm x 10 mm busbar arrangement with one to three busbars.

How it works

• The conductor or busbar passes through the current transformer opening.
• The transformer measures the AC current flowing through the primary conductor.
• The first output provides AC 0-5 A or AC 0-1 A for compatible measuring and metering equipment.
• The second output provides a DC 4-20 mA signal for PLC or DCS analogue inputs.
• The 4-20 mA output uses DC 24 V auxiliary power supplied by the PLC.

Why choose this product

• Provides both conventional AC current measurement and a 4-20 mA automation signal.
• Allows a single current transformer to serve measuring and control system requirements.
• Suitable for higher-current installations where the SM-200II configuration is appropriate.
• Supports integration with PLC and DCS analogue input systems.
• Available with different primary current ratios within the manufacturer's specified range.

Benefits

• Simplifies current measurement and signal transmission requirements.
• Provides a familiar 4-20 mA signal for industrial automation systems.
• Supports connection to conventional AC measuring instruments.
• Provides a practical option for monitoring high-current electrical circuits.
• Suitable for installations where current measurement needs to be made available to both metering and automation equipment.
