1 channel RS485
3) Friendly power supply
Support emergency credit
4) Audio and visual alarm
Low credit can be indicated and alarmed via buzzer and LED
5) Events logs(power purchasing, power outage, overload, under
voltage, over voltage, current reverse, etc.)
6) Load control
Relay inside,it can disconnect the load under low credit or
overload
7) Metering and measuring
It can measure the import, export and total active energy, reactive
energy metering; and also can measure various parameters voltage,
current, power and power factor measuring
8) TOU
4 tariffs;2 sets of time period tables; 8 time periods can be set
in 24 hours; support public holidays and weekends.
