DDSU666 Single phase electronic
energy meter user manual
1.Overview of products
1.1 Applicable range
The DDSU666 meter mainly applied
into the measurement and display for
the photovoltaic system parameters in
the electric circuit including voltage,
current, power, frequency, power
factor, active energy, etc. The network
can be realized through RS485
communication interface and external
device.
Adopting
the
standard
DIN35mm din rail mounting and
modular design, it is characterized
with small volume, easy installation
and easy networking.
