Joining meters are suitable for measuring active energy in single phase for direct currents upto 100 A; in three phase (three wire or four wire at balanced or unbalanced) networks, for directly connected loads upto 100A; and for operation through CT or CT & PTs.
Specification
The measuring and technical characteristics comply with IS:13010, IEC 521 and BS 5685. Meters are available in accuracy class 1 or accuracy class 2.
DDS223 single phase electronic watt-hour meter adopt a large scale of integrated circuits and SMT technology, whole screen and anti-jamming structure.
Features:
(1)High reliability, low power loss, high accuracy, wide load capacity.
(2)Can accurately measure active energy power from positive direction and negative direction, and accumulative total in the same direction, and has function of anti-stealing electricity.
(3) adopt photo-electricity coupling no power pulse output, and indication using electricity by LBD, and can realize collecting reading meter so as to control using electricity and management. It is used for measuring active energy power loss in frequency 50 Hz or 60 Hz single phase AC electricity net and which is installed in meter box indoors or outdoors.
