The QCM11 is a single-phase IC card prepaid meter built for reliable revenue management and controlled energy consumption. Its secure one-meter-one-card design, overload protection, and automatic credit control help ensure accurate billing and dependable prepaid operation.
Fail-Safe Offline Revenue Protection: Implements strict cryptographic one-to-one card validation logic, ensuring that tenant power consumption data is thoroughly secure and immune to cross-device spoofing or external signal interference.
Heavy-Duty Load & Arrears Control: Equipped with an internal latching relay capable of handling continuous maximum currents up to 100A, driving immediate automated circuit isolation the exact millisecond the prepaid credit reaches zero balance.
Industrial Enclosure Resilience: Enclosed in a flame-retardant IP54-rated heavy casing (215×112×58mm), calibrated to ensure high-accuracy Class 1.0 active measurement profiles across extreme temperature ranges from −25°C to +65°C.
1. STS standard protocol ensures an open and secure operating system
2. Prepayment and post-payment modes are switchable for users’ convenience
1. Bi-directional measurement of active energy.
2. Prepayment is made via a numeric token logged in the IC card.
3.One meter, one card, ensures data for power consumption safety and reliability.
4.Overdraft/Credit power usage.
5. Overload detection, control, and alarming.
6. Support errors self-detection function.
7. Automatic cutoff when the credit is zero.
