YTL - prepaid meter 1000imp/kwh Split Type Electric Energy Meter STS Approved Dlms Smart Remote Reading
It is a Smart STS Single-phase meter system, with RS485, RF, LoRa, PLC optional communication. Be able to measure in STS mode, currency mode, and post-paid (traditional) mode. Meter connects with In Home Display (IHD) for user reading and operation. Data will be sent to master station via DCU for management. Through meter keypad, IHD keypad and Master station software, users and administrators can operate the recharging.Meter send data to IHD regularly, including the instantaneous data (like voltage, current, power), consumption energy, remaining energy, some parameters and event flag.After IHD receiving data, will display the parameter information of corresponding meter.
Anti-tampering
Support load ground connection, switch detection, influence of external magnetic field, abnormal voltage record.
Tariff
Divide into weekday timetable and weekend timetable, with 8 time period and 8 tariffs. Every timetable has a backup table for remote updating of backup timetable and configure the switching time. Meter will automatically switch the tariff table at the switching time.
Communication
Meter support IR,RS485/LoRa, baud-rate: 9600/PLC, baud-rate: 4800.
Event
Open cover, magnetic field, load ground connection, reserve current, over-voltage, low-voltage, low-frequency, overload, power-fail, low remaining power, and token record.
Measurement
Meter measures voltage, current, active power, reactive power, frequency, power factor, MD in the current month, MD of last 1 month, MD of last 2 month, the absolute value of total active energy, the absolute value of total active tariff energy, total input energy of the current month, total input energy of last 5 month, total output energy of the current month, total output energy of last 5 month, and total reactive energy.
Mode
Meter has 3 operation modes: STS token mode, currency prepaid mode and post-paid (traditional) mode, which can be switched. And the currency mode can be divided into tariff mode and step price mode. Modes can be configured through communication.
STS operation
Enter 20-digit token via keypad of meter or IHD, the meter display will be green Pic 1 if recharging is successful, will be red Pic 2 if is failed.
