Split Core Current Transformer – 5–75A Primary, 100–333mV Output
Compact split-core current transformer designed for low-current circuits from 5A to 75A. Features safe 100–333mV voltage output for direct connection to digital energy meters, IoT monitoring devices, and data loggers.
This low-range Split Core Current Transformer is engineered for accurate measurement of small to medium AC loads in commercial and light industrial installations.
With a primary current range of 5A to 75A and a low-voltage secondary output of 100mV to 333mV, the transformer is ideal for modern electronic metering systems requiring voltage-input CT signals.
Unlike traditional 1A or 5A secondary CTs, the millivolt output provides improved safety and simplified integration with:
-
Digital energy meters
-
IoT energy monitoring gateways
-
Building Management Systems (BMS)
-
PLC and SCADA systems
-
Data loggers
-
Smart facility monitoring platforms
The split-core design enables fast, non-intrusive installation around existing conductors without disconnecting wiring—making it ideal for retrofit upgrades and live electrical environments.
Operating at 50–60Hz, the transformer maintains a phase angle error of less than 2° at 50% rated current, supporting reliable sub-circuit energy tracking and load analysis.
Typical applications include:
-
Lighting circuits
-
Small power circuits
-
HVAC equipment monitoring
-
Solar inverter sub-circuits
-
Machinery and plant monitoring
-
Energy audits and facility upgrades
