DIN-Rail Mounting Split Keypad Prepaid Energy Meter DDSY1398
DIN Rail Mounting Split Keypad Prepaid Energy Meter,Energy Measurement,STS,Load Control,Programmable Low-Credit Warning,Tamper Detection,Optical Port Interface,RS485/RF,IP54,50Hz
Main Features
Measures active and reactive energy consumption
Records last one to sixteen months energy data
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.
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
