High Accuracy AC/DC CT 400:5 220V Input — EcoNewlink Current Transformers

High Accuracy AC/DC CT 400:5 220V Input — Product Category

Product Overview

The High Accuracy AC/DC CT 400:5 220V Input line provides precision current measurement for modern power systems. These CTs feature a 400:5 ratio with AC/DC sensing capability and a 220V input reference where applicable, ensuring reliable metering and protection. Built for integration with multifunction power meters, energy meters and intelligent data platforms, they support accurate billing, protection and energy management.

Key Technical Features

Designed to meet demanding accuracy and reliability requirements, our CT series delivers tight linearity, low phase error and selectable accuracy classes (eg. 0.2, 0.5). The 400:5 transformation ratio simplifies panel design while maintaining wide dynamic range. AC/DC compatible sensing, robust insulation, and thermal stability make these CTs suitable for both conventional and modern inverter-connected grids. Manufactured under 5S automated lines, product defect rate is ≤0.01%.

Applications & Integration

These CTs are ideal for electrical panel builders, EPC contractors, and system integrators implementing distribution boards, substation metering, energy monitoring and protection schemes. They pair seamlessly with EcoNewlink Multifunction Power Meters and third‑party devices, supporting OEM/ODM system integration and smart grid telemetry. Typical applications include commercial, industrial and renewable energy installations.
