Main Features
＃ FSK modulation with DSP technology
presents strong noise resistance. It ensures communication
capability even under heavy line loading conditions
＃ Carrier frequency band: 9 kHz ~ 95 kHz
(reserved for utility companies)
＃ Baud rate: 300 ~ 1200 bps
＃ Dual channel input enables the ability
to detect reverse rotation by sensor-type meter. This prevents
error arising from meter disc jittering motion.
＃ 15 pins single inline direct insertion
packaging, 38.1 x 19.05 mm.
＃ Unit can be easily installed into
electric meter by using mounting and power supply components
supplied by us.
＃ Calculation by time-of-use. The
time-of-use can be remotely set.
＃ When used with the full metering suite
from Archnet, the system can be used for line loss, phase balance
analysis and other management function.
＃ Bi-directional communication enables
overdue payment reminder and other similar functions.
