The 40mA model is specifically calibrated to work with milliamp secondary output Current Transformers (CTs). Standard models usually require 1A or 5A CTs. This makes the 40mA version ideal for compact or 'smart' CTs often used in solar PV zero-export kits.<\/p>
Yes. To ensure compatibility and safety for the Australian market, this meter comes bundled with 3 x specialized 40mA secondary output CTs。
Yes. The meter is bidirectional, meaning it tracks energy flow in both directions (Import from grid and Export to grid), making it perfect for solar PV system performance tracking.<\/p>
It features a built-in RS485 Modbus RTU interface, which is the industry standard for connecting to data loggers, PLC systems, and building management systems (BMS).<\/p>
The meter is highly versatile. It supports 3P4W (Three Phase Four Wire) which uses a neutral, as well as 3P3W (Three Phase Three Wire) and 1P2W (Single Phase) configurations.<\/p>
Yes, it features a highly visible blue backlit LCD display, ensuring you can read the parameters easily even in dark electrical cabinets.<\/p>
The SDM630MCT-40ma provides Class 1.0 accuracy for active energy according to IEC 62053-21, providing professional-grade precision for energy auditing and monitoring.<\/p>
The RS485 loop can extend up to 1200 meters (approx. 4000 feet) under ideal conditions using high-quality shielded twisted pair cabling.<\/p>
The unit has a width of 72mm, which corresponds to 4 standard modules on a 35mm DIN rail.<\/p>
All Eastron smart meters come with a standard 24-month warranty, covering manufacturing defects and hardware performance.<\/p>
