QBM11-2 is a single-phase meter that features a compact and cost-efficient design that can measure active energy and maximum energy absorbed, and show these data on an LCD screen. Automatically performing summer-winter hours, keeps desired information and programs in its memory, accessing this information when desired. It has been manufactured with advanced technology and focuses on the necessary and offers an excellent price-performance ratio.
Optimized Physical Footprint: Streamlined 180×100×46mm structural body reducing total deployment volume by over 30% compared to legacy residential devices, with a bare net weight of just 0.3kg.
Automated Tariff Firmware: Integrated with independent seasonal and time-zone clocks for flexible TOU (Time-of-Use) energy tracking, paired with automated calendar algorithms adjusting for summer-winter seasonal offsets.
Secure Revenue Perimeter: Outfitted with an integrated physical event recorder tracking unauthorized cover and terminal-block breaches, paired with local optical protocol infrastructure.
1. Bi-directional measurement of active energy.
2. The meter has a multi-tariff (TOU) measurement function.
3. The LCD can display the real-time clock, current, voltage, and active power, etc.
4. Records and displays the data of the current month’s Maximum demand.
5. Stores the monthly cumulative active energy of the last 12 months.
6. Base cover and terminal cover open detection and record.
7. Display readable without main power (RWP).
