Place of Origin:
Hunan
Brand Name:
Stron
Certification:
STS
Model Number:
STE38-S
Ste38-s has professional and high-performance three-phase metering function, which is composed of three-phase prepayment watt hour meter and sub key CIU (customer interface unit). It provides keys for remote recharge and information query, which is its core competitiveness, advanced and easy to use. Lora radio frequency is used for communication between the instrument and CIU, which is effective and low cost. The communication distance is about 1km.

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.
