Get quick answers about energy meter selection, communication and system integration, certification, ODM cooperation and project requirements.
Start with the electrical system, measurement point, voltage, current, phase and wiring, then define the required accuracy, communication, installation format and certification. YTL can help match these requirements to a suitable standard model or an OEM/ODM evaluation path.
Communication capability depends on the exact model. Selected YTL products support interfaces and protocols such as RS485, Modbus RTU, M-Bus, DL/T 645, DLMS/COSEM, Ethernet, Wi-Fi, 4G/LTE, PLC and RF for remote reading and system integration.
Yes. Depending on project feasibility, YTL can evaluate product configuration, firmware and communication requirements, private-label branding, packaging, documentation, testing and certification support for ODM projects.
No. MID certification is model- and configuration-specific. Buyers should verify the exact model, intended market and supporting certification documents before using a meter for regulated or billing applications. YTL can provide available model-specific compliance documents for project evaluation.
