COMMODITY:Three Phase Anti-backcurrent Smart Power Meter
Model NO:DTSD9866-CD4-NL
Application Scenarios:Used in photovoltaic power generation system to actively prevent or control the situation of reverse current when the power generation power is greater than the actual load.
PRODUCT OVERVIEW
Using Din rail installation,especially suitable for applications with small Installation space,industry standard wide temperature
LCD screen,with Good high and low temperature display characteristics,to achieve full power measurement and display,including
dynamic alarm,switching Input and output status,SOE event recording,complex rate,harmonics,etc,support RS485 communication,
can be configured to Modbus -RTU Protocol.
Working Principle:
The Meter to be used with the inverter and the inverter adjusts the output power in real time through the power size and direction
of the network access port collected by the RS485 communication reading meter to achieve the anti-backflow function.
