APPLICATION:

 

CL790D Energy management terminal adopts micro-electronic technology, computer technology and controls energy management with load control. The model is a coordinate product with power load management host station, which is significant part to realize power demand side management. The mode is applied to realize load inspection and control, AMR and fraud proof.

 

FUNCTIONS:

 

Energy Inspection & Load Control

·Sample current, voltage, active power, power factor & grid wave data at real time.

·Provide events such as: over voltage, loss voltage, off phase, phase loss, phase failure, overload and current unbalance with M.D. and occurred time.

·Support electricity control by period, monthly energy control, purchase energy control and remote control.

·Automatic Meter Reading able to realize meter reading via RS485, Max. is 8pcs. Reading data include: total active/reactive/forward/reverse energy, energy for time using, total 4 quadrants energy, demand, voltage, current and active/reactive power.

 

Energy Consumption:

·Record the time of voltage’s limit exceeding and voltage qualified rate.

·Check measurement faults such as: clock abnormality, battery loss .

·Able to check if the cabinet door had been opened or not.

·Record all the parameters at happening of the event for later analysis.

·Abnormally alarm information report.

·Support report auto. and fixed point test.

 

Data Storage:

·All data can be automatically stored at power failure, storage capacity is 2MB, and saving time is not less than 10 years.
