Main Features


Energy Measurement 

Measures active and reactive energy consumption

Records last one to sixteen months energy data

20 digit Standard Transfer Specification(STS)

Credit data transferred from a point of sale (POS) or vending system is encoded into a numeric token in a 20 digit number using the Standard Transfer Specification (STS) encryption techniques, complies with IEC62055 protocol

Load Control

Upon balance reaches 0 or allowable overdraft agreed by both parties, will the meter shut itself down automatically. The power can be recovered automatically after inputting new purchased energy token. 

Programmable Low-Credit Warning

The meter can be programmed for setting user credit warning threshold, when the meter’s residual balance reaches credit warning threshold, the meter will initiate visible and audible warnings

TOU

4 tariffs, 14 time zones, 8 Day Sections, 100 holidays
