The QPM16-D-1 is a compact STS DIN-rail prepaid meter designed for modern prepaid energy management. Working together with a Customer Interface Unit (CIU), it enables convenient token entry, balance inquiry, and energy consumption monitoring. Supporting RF, PLC, and G3-PLC communication and fully compliant with the STS standard, the QPM16-D delivers reliable performance and flexible deployment for residential communities, apartment complexes, dormitories, and metering projects.
Advanced Fraud & Tamper Control: Outfitted with an intelligent hardware-level Fraud Protection Function, the meter executes an instantaneous, automated internal relay disconnection at the exact millisecond any unauthorized terminal cover breach or enclosure opening is detected, remaining highly active even during total grid blackouts.
Dual-Circuit Load Management: Integrates a heavy-duty double-circuit on-off relay topology designed to safely handle maximum current surges up to 100A, providing grid operators with programmatic control to isolate specific sub-loads or enforce immediate zero-credit cutoffs.
Open Interoperable Protocol: Complies fully with strict IEC 62052-11 standards and operates on the open-protocol DLMS/COSEM (Mode E), allowing the device to adapt flawlessly to existing online vending systems via modular PLC, G3-PLC, or RF communication.
1. STS standard protocol ensures an open and secure operating system.
2. Optical communication, open protocol: DLMS/COSEM (E mode).
3. Prepayment and post-payment mode switchable for users’ convenience.
4. Local firmware upgrade.
1. Measuring forward and reverse active energy in tariff.
2. Measuring forward and reverse reactive energy in tariff.
3. Instantaneous value measurement.
4.12 months' billing data and other frozen data for inquiry.
5. Block or slide mode configurable for maximum demand.
6. Import and export active MD in tariff with time stamp.
7. Import and export reactive MD in tariff with time stamp.
8. Real-time clock: clock with calendar, timing, leap year automatic conversion function.
9. Multiple event detections and records with categories of operation, power grid, and tampering.
10. Terminal cover open detection and record.
11. Prepayment mode via a numeric token with extended ways of recharging.
12. Channel quantity customized before leaving the factory; up to 8 channels.
13. Data for load profile record configuration
14. Wired split-type meter and wireless split-type meter can be selected.
15. Wired communication with CIU via M-bus or PLC, wireless communication with CIU via LoRa.
16. User-friendly mode for energy supply for low credit during weekends or holidays.
17. Emergency Credit for a certain sum of energy supply depending on the user’s credit level.
18. Double-circuit on-off control
19. Fraud protection function: The relay will be disconnected for fraud protection once it detects terminal cover open events.
