summary:
NB rail single-phase prepaid energy meters are mainly used in the field of energy management for single-phase networks with frequencies ranging from 45 to 65Hz. It can measure the electricity information in the power grid and exchange data with the upper computer through encrypted IC card or 485 communication. The instrument is equipped with a high-power relay (100A) that can achieve local opening and closing operations, thereby realizing prepaid functions; Users can set the internal parameters of the energy meter according to the actual situation on site, which is convenient to use, easy to operate, and has high accuracy; Widely used in various fields such as residential buildings, smart buildings, shopping malls, collective dormitories, schools, etc.
The rail type single-phase prepaid energy meter is a direct input type energy meter with a maximum input current of 100A.
The product complies with the relevant standards of GB/T17215 and GB/T17883, and is an ideal electric meter for reforming the traditional electricity system and improving the level of electricity management.
Main functions:
| name | describe | configuration |
| Parameter measurement | U. I, P, Q, S, PF, F, etc | standard configuration |
| Energy Measurement | Single phase energy metering | |
| cost control | IC card or remote cost control, pay first and then use electricity, with built-in relay for local opening and closing | |
| overload protection | Real time detection of power value. If it exceeds the threshold value, it will automatically trip, eliminate the fault point, and restore power supply after inserting the sales card | |
| display | 7-digit segment code LCD paging wheel display | |
| communication | RS485 interface, Modbus RTU protocol | standard configuration |
| Malignant load control | Detect the instantaneous step power, if it is greater than the set value, it will automatically trip, remove the malignant load, insert the relay closing card or send a closing command to restore power supply | standard configuration |
