This SDM120CTM-40mA kit is calibrated for 40mA secondary-output current transformers and includes an ESCT-TA16 split-core CT, 120A primary / 40mA secondary. It is designed for compact single-phase metering in solar PV, EV charging, and energy-management applications where a 40mA CT input is required.
Yes. The kit includes 1 x ESCT-TA16 split-core CT, 120A primary / 40mA secondary, matched to the SDM120CTM-40mA meter input for convenient installation and compatibility.
Yes, the meter is bi-directional and supports 4-quadrant measurement, making it ideal for tracking both grid consumption and solar feed-in.
The built-in RS485 interface supports transmission distances of up to 1000 meters (approx. 3300 feet) using shielded twisted pair cabling.
This Australian product page focuses on the RCM-approved SDM120CTM-40mA kit. Before installation, please confirm local electrical, metering, and grid-connection requirements with a qualified electrician or solar installer. Do not rely on MID certification unless a project specifically requires it and the exact supplied model has been verified for that use.
Yes. Its slim 18mm DIN-rail format, RS485 Modbus RTU communication, and included ESCT-TA16 120A/40mA split-core CT make it suitable for single-phase EVSE energy monitoring, load management, and solar/EV system integration. For formal billing or revenue-grade metering, confirm the required certification for your installation before use.
Yes. The included ESCT-TA16 split-core CT is 120A primary / 40mA secondary. The meter primary CT ratio can also be configured from 5A up to 9999A via the front button or Modbus commands when used with compatible 40mA CTs.
The SDM120 is an ultra-compact 1-module device, occupying only 18mm of space on a standard 35mm DIN rail.
You can remotely monitor Voltage, Current, Active Power, Reactive Power, Apparent Power, Power Factor, Frequency, and total/import/export Energy.
The SDM120CTM-40mA kit comes with a standard 24-month product warranty from the date of purchase.
