Overview

The smart current sensor utilizes the principle of electromagnetic induction to perform real-time measurement of alternating current in power grids. It employs constant current and linear compensation technology to isolate and convert the current into a standard direct current signal output, or transmits measurement data via an RS485 interface (Modbus-RTU protocol). Powered by a safe voltage of DC24V or 12V, SUCH AC current sensor is widely applicable in industrial automation fields.

Feature

Real-Time Monitoring: Utilizes electromagnetic induction to continuously measure AC in power grids with high accuracy.
Signal Conversion: Adopts constant current and linear compensation technology to output a stable DC signal.
RS485 Communication: Supports Modbus-RTU protocol via RS485 interface for digital data transmission.
Safe Power Supply: Operates on DC 12V or 24V for reliable and safe usage in industrial settings.
DIN Rail Installation: Designed for quick TS35 DIN rail mounting in control cabinets.
Rotatable Structure: Features a rotatable housing for flexible installation in various orientations.
Industrial Applications: Suitable for automation systems, motor control, energy monitoring, and smart grids.

Wiring Instructions

Smart current sensor wiring instructions

1: + Power supply positive terminal (note: do not reverse the positive and negative terminals of the power supply)

2: - Power supply negative terminal

3: OUT- Analog output negative

4: OUT+ Analog output positive

Indicator light definition: During normal operation, when no 485 communication is connected, the red light flashes once every 1 second; When the current sensor successfully connects to 485 communication, the red light flashes rapidly.

Note: The current sensor uses spring-loaded terminals for wiring. It is recommended to use shielded cables with a cross-sectional area of 0.75mm² for power supply, output, and RS485 communication connections.

FAQ

Q1: Is the AC current sensor suitable for both indoor and outdoor installation? ❯

The sensor is primarily designed for indoor use. For outdoor installation, it must be housed in a weatherproof enclosure to protect against moisture and dust.

Q2: Can multiple sensors be installed in the same control panel? ❯

Yes, multiple units can operate side by side, as long as they are powered properly and electromagnetic interference is considered during wiring layout.

Q3: Is there any warm-up time required before accurate measurement? ❯

The sensor provides accurate readings immediately upon power-up, but in high-precision applications, a warm-up time of 2–3 minutes may improve stability.
