The QCM31 is the latest developed new-generation prepayment single-phase energy meter with IC card function. The meter is used to measure electrical energy accurately for commercial, industrial, and residential customers. This type is well used in multiple application scenarios, such as EV charging systems, hotel systems, etc. The QCM31 has reliable performance and high stability in metering and measurement. The good quality brings the long service life to the users.
Independent LED indicators clearly signal power supply status, energy pulse output, load current flow direction, and data communication activity at a glance. An optional RS485 communication port enables seamless remote data collection and parameter configuration for centralized power management. Equipped with an integrated magnetic latching relay, the device can automatically cut or restore power to connected loads as required. It also keeps permanent event logs to record abnormal incidents, including damaged IC card usage and overdraft power consumption for full usage traceability.
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. Measure the instantaneous value, such as voltage, current, active power, power factor, freauency.
3. Display readable without main power (RWP)(optional).
4. Backlights to increase readability in low light conditions (optional).
5. LCD with two options: cycle display (default) or key display item by item. Can set the cycle display interval. Can select the data item to display.
6. LEDs indicate the power supply state, energy impulse signal, load current flow direction, and the data communication state separately.
7.RS485 data communication port. (optional).
8. Built-in magnetic holding relay supports load on-off function.
9. Event recording: IC card crack event, overdraft event.
