BAK Series Split Core AC Current Transducer

Acrel BAK Series Split-core products utilize the principle of electromagnetic induction to perform real-time measurement of AC current in power grids. Using constant current and linear compensation technology, they isolate and convert the measured current into a standard DC signal output. Operating on a safe voltage of DC12V or 24V, they can be widely used in industrial automation fields.

Wiring

V+ —— Power Positive (Note: Do not reverse power positive and ground)

DO-、DO+ —— Digital Output (Switch) Interface

V- —— Power Ground

A、B —— RS485 Interface

OUT- —— Analog Output Negative

OUT+ —— Analog Output Positive

Cable is through-hole (pass-through) input

Indicator Definitions:

RUN: Normal operation. When 485 communication is not connected, the RUN indicator shows green, blinking once per second. When the current sensor successfully connects to 485 communication, the RUN indicator blinks rapidly.

Alarm: After the alarm function is enabled, when the input current reaches 120% of the sensor's range, the Alarm indicator lights red steadily and the relay output closes. When the input current drops below 110% of the sensor's range, the Alarm indicator turns off. If the alarm function is not enabled, the Alarm indicator remains off and the relay does not close.

Notes:

(1) The device uses removable terminal blocks. It is recommended to use shielded wires with a cross-sectional area of 0.75mm² for the power, output, RS485 communication, and digital output interface sides.

(2) Please refer to the wiring diagram on the physical housing for specific wiring connections.
