Main functions
● With the export energy metered as total import energy, and capable of recording export energy alone.
● Prepayment CPU card, higher security and reliability.
● TOU
Four tariffs; two sets of time zone tables; two sets of time period tables; support public holidays and weekends
● Step tariffs
● Friendly power supply management
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, 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 configured for current reverse, magnetic influence, phase bypass, meter cover open, etc.
● Load control
Detecting the customer’s load status, it can alarm or disconnect the power supply when under overload.
● Communication interface
One far infrared interface and one RS485 are available.
Our advantage
