ACREL AKH-0.66S S-50ii Dual-Winding Current Transformer
ACREL AKH-0.66S S-50ii Dual-Winding Current Transformer is a dual winding current transformer for electrical current measurement, remote monitoring and motor protection applications. It provides separate secondary windings for current indication and remote monitoring, with primary current ratios from 600 A to 1250 A. The S-50II model accommodates a 50 mm x 10 mm busbar arrangement and uses a compact current transformer design for installation within electrical systems.
The ACREL AKH-0.66S S-50ii Dual-Winding Current Transformer is part of Acrel's AKH-0.66S series of dual winding current transformers. The transformer has two independent secondary windings. The first secondary winding is intended for current indication and can be specified with a secondary current of 5 A or 1 A. The second winding provides a 20 mA output for remote current monitoring and can be used with compatible monitoring equipment such as the Acrel ARTU-M32 remote measurement unit or ARD3 motor protection device.
For the S-50II model, Acrel lists primary current ratios of 600 to 800 A, 1000 A and 1200 to 1250 A, depending on the selected configuration. The corresponding measurement winding burden varies with the selected ratio, while the remote monitoring winding is specified at 0.02 VA.
How it works
- The conductor or busbar carrying the primary current passes through the current transformer.
- The transformer converts the primary current into a proportional secondary signal.
- One secondary winding provides a 5 A or 1 A output for current indication.
- The second secondary winding provides a 20 mA output for remote monitoring.
- The separate outputs allow measurement and remote monitoring functions to operate from the same current transformer.
Why choose this product
- Provides two secondary windings for separate measurement and monitoring functions.
- Supports high primary current applications from 600 A to 1250 A for the S-50II configuration.
- Provides a 20 mA secondary output for remote monitoring equipment.
- Designed for applications where current measurement and motor protection monitoring are required.
- Available with 5 A or 1 A measurement secondary options.
Benefits
- Allows measurement and remote monitoring to be handled through separate secondary windings.
- Helps integrate current monitoring into compatible electrical monitoring equipment.
- Suitable for higher-current electrical circuits.
- The transformer design provides a practical method of obtaining proportional current signals without directly connecting measurement equipment to the primary circuit.
