FUNCTIONS:
Realize automatic meter reading via low voltage wire line.
Separately measure reverse/forward active/reactive power.
Record the date and meter status data at hour, stock the auto reading data.
Test the power supply quality, record the power failure and user information.
At power failure, the data can be stored for more than 10 years.
Calibrate the clock by the collector and all the system.
Phase failure, reverse power alarm and etc.
Remote switching control function.
RS485 and infrared communication port.
FEATURES:
The data collective module adopts the power line carrier technology, and the communication via low voltage wire line.
Power wire carrier meter reading system includes carrier wave collection device, management center & DTSI P LC meter.
Meter status monitoring, power supply line quality monitoring and acception function of remote control.
Three phase power supply, and it keeps running even under only one phase.
