DDS720/721-C2 single phase LCD kWh meter

APPLICATION:

The meter is used for the power measurment of single phase power consumer and suitable for concentrative reading and maintenance.

.

FUNCTIONS:

       Measure reverse and forward energy, reverse energy is measured as forward energy..

       Record current energy, energy of last month, energy.of the month before last month

       LCD display. display mode can be set.

       it can display for a long time at power failure.

       Infrared check and button check function.

       Real time clock.

       Program function and the last three time program record function.

       RS-485 and infrared communication port to realize meter reading and programming.

FEATURES:

       Active energy measurement, no need to calibrate for a long working time.

       LSI design and SMT technology, less spare part, less power consumption, simple structure.

       New energy LSI, wide dynamic working range.

       Active energy meter keeps a good linearity error within the range 1%Ib~Imax.

       Use quality component with long service life, the accuracy cannot be affected by the frequency, temperature, voltage, harmonic. It is reliable and with long service life

       RS485 communication port realizing remote meter reading..

       High security function, preventing meter fast running, rmeter esetting and parameter. setting

       Display can be set, with back light.
