The QBM11-3 is a compact, advanced single-phase two-wire electricity conventional meter capable of measuring active and reactive energy as well as maximum demand, with data displayed on an LCD screen. Compliant with DLMS-COSEM standards, it supports meter reading via IrDA and RS485 communication. Its built-in Real-Time Clock (RTC) enables multi-tariff functionality and seasonal switching, while data is stored in non-volatile memory.
Comprehensive Quad-Quadrant Sampling: Fully capable of running bi-directional measurement schemas mapping both active energy and reactive energy factors under varying heavy load demands.
Standardized Utility Interoperability: Engineered for native DLMS/COSEM compliance, ensuring drop-in compatibility with central Head-End Systems (HES) over dual-channel communication media (RS485 terminal line + IrDA wireless).
RTC-Driven Synchronization: Driven by an industrial-grade internal Real-Time Clock (RTC) ensuring microsecond seasonal switching, paired with full RWP visibility and a continuous 12-month frozen billing memory stack.
