Split Core Current Transformer – 10–150A Primary, 100–333mA Secondary
Compact split-core current transformer for 10A–150A conductors with low-current mA secondary output. Ideal for sub-circuit monitoring, IoT energy systems, smart metering, and building energy management applications.
This Split Core Current Transformer (CT) is designed for accurate AC current measurement in low to medium current circuits.
With a primary current range of 10A to 150A and a low-current secondary output of 100–333mA, the unit is suited for direct connection to modern electronic energy meters and monitoring devices.
The low mA secondary output enhances safety and simplifies wiring when interfacing with:
-
Digital energy meters
-
IoT monitoring gateways
-
Building Management Systems (BMS)
-
Data loggers
-
PLC and SCADA systems
-
Sub-circuit load monitoring applications
The split-core construction allows quick installation without disconnecting existing conductors, making it ideal for retrofit projects and live electrical environments.
Operating within standard 50–60Hz AC systems, the transformer maintains a phase angle error of less than 2° at 50% rated current, ensuring reliable energy data and load analysis.
Typical applications include:
-
Commercial distribution boards
-
HVAC equipment monitoring
-
Solar inverter AC output circuits
-
Lighting and power sub-circuits
-
Small machinery and plant monitoring
