Split Type Three Phase Prepaid Energy Meters IEC standard STS compliance
function
Prepayment: STS standard, input 20 tokens to recharge
Low credit alarm: the alarm value can be set by inputting the corresponding token
Switch between prepayment and post payment: the meter can switch to prepayment mode or post payment mode
Load control function: if the current power exceeds the threshold, the instrument can program the load control threshold. The meter will cut off the user's load.
Self check: the instrument has self check function, which can test LCD and relay, and report the result directly
Tamper proof: when the magnetic field is detected and the cover is opened, the instrument will automatically close the valve
Time of use electricity price: the time of use electricity price can be set by inputting the corresponding token
Overdraft collection: Electric overdraft can be collected day by day or monthly
Information query: consumers can query credit balance, total purchase amount, total credit and other data by entering short code.
