ACREL AKH-0.66 SM-60ii Dual Winding Current Transformer
ACREL AKH-0.66 SM-60ii Dual Winding Current Transformer is a dual-output current transformer designed for AC current measurement and automation systems. It provides an AC 0-5A or AC 0-1A output for measuring and metering equipment, together with a DC 4-20mA output for PLC and DCS systems. The SM-60II configuration accommodates 60 mm x 10 mm busbars and supports primary current ratios from 300A to 2000A, depending on the selected ratio.
The ACREL AKH-0.66 SM-60ii Dual Winding Current Transformer is a dual-output current transformer for AC current measurement and automation applications in low-voltage power systems. It provides two independent output signals from the same current transformer.
The first output is available as AC 0-5A or AC 0-1A for measuring and metering equipment. The second output provides a DC 4-20mA signal for connection to PLC or DCS analogue inputs. The 4-20mA output requires a DC 24V auxiliary supply supplied by the PLC.
The SM-60II model is designed for installation around a 60 mm x 10 mm busbar, with one or two busbars supported according to the manufacturer's specification. Available primary current ratios for this model range from 300A to 2000A.
How it works
- The conductor or busbar passes through the current transformer.
- The transformer provides an AC 0-5A or AC 0-1A output for conventional measurement and metering equipment.
- A second output converts the measured current into a DC 4-20mA signal for PLC or DCS analogue monitoring.
- The DC 4-20mA circuit is powered by a DC 24V auxiliary supply from the PLC.
Why choose this product
- Provides two output types from one current transformer.
- Allows conventional AC current measurement alongside analogue automation monitoring.
- Suitable for integration with PLC and DCS systems.
- Available with multiple primary current ratios to suit different current monitoring requirements.
- Designed for use with 60 mm x 10 mm busbars in the SM-60II configuration.
Benefits
The dual-output arrangement can simplify current monitoring where both local or conventional measurement and an automation-system input are required. The 4-20mA signal provides a standard analogue interface for industrial control and monitoring equipment, while the AC output can be used by compatible measuring or metering devices.
