Product Description

Applications, Features and Sphere of Application

Main features: Application of computer management, power utilization after purchasing power; limitation of maximal service power within the rated current range (prescribed by power supply department); one card only for one watt-hour meter, no electricity interruption even with the loss of the card and ensuring the power continuation after the re-registration; bilateral transmission of data and automatic power- cutting off to warn users to purchase power ; automatic switch-off operation when the electric quantity hits zero ; certain software design of anti-electricity-theft and so on .

Installed in the watt-hour meter boxes indoors or outdoors,DIN rail three phase prepaid energy meter apply to active power meter of frequency of 50HZ or 60HZ. Its ambient temperature ranges from -10℃ to 50℃ and its relative humidity is no more than 85%. It should stay away from the influence of corrosive gas, dust, salt mist and condensation.
