Overview of products
1.
1.1 Applicable range
The DTSU666 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,
network can be realized through
RS485 communication interface and
external device. Adopting
standard DIN35mm din
mounting and modular design, it is
characterized with small volume, easy
installation and easy networking.
