Single Phase STS Split Type Prepaid Meter communication as per IEC62056-21

General introduction

1) Single Phase STS Split Type Prepaid Meter communication as per IEC62056-21 has the functions such as metering, monitoring, alarm, display, communication and load control, etc.

2) It adopts STS standard encryption algorithm to exchange the information based on TOKEN, Advantages of the meter are high metering accuracy, high level security, strong compatibility, easy operation, etc.

3) Work with UIU.

Main functions

• UIU communication interface: PLC, RF or twist-wire is optional.
• TOU: Four tariffs; two sets of time zone tables; support public holidays and weekends; two sets of time period tables.
• Step tariffs
• Friendly power supply: Support emergency credit
• Events logs: Detecting and recording events such as current reverse, magnetic influence, phase bypass, meter cover open, terminal cover open, overvoltage, under voltage, etc.
• Anti-tamper: Detecting current reverse, magnetic influence, phase bypass, meter cover open, terminal cover open etc., at the same time, the meter can disconnect power supply which is configurable when the tampers occur.
• Audio and visual alarm: Audio and visual alarm which can be configurable can be for power flow reverse, magnetic influence, phase bypass, meter cover open, terminal cover open, etc.
• Load control: Detecting the customer's load status, it can alarm or disconnect the load when overload.
• Communication interface: Optical port and RS485 interface are available.
