three phase prepaid energy meter

Main functions:(1)Steady accuracy of active electric energy measurement generally free effect produced by frequency,temperature ,voltage, and higher-order ware, adjustment-free after delivered, and check period prolongable;(2)Safe and reliable data owing to the encrypted card for two-way transmission of data;(3)Purchase card capable of copying from temeter the latest data of electricity consumed for eawy monitoring of the operationwtatus;(4)With electricity purchased in advance, supplying power after payment, interrupting power when electricity is run out, and no credit given; (5)Residual electricity alarm function with the alarm value set up, power interrupted at overturn, and power supply recovered by inseerting the card;(6)Load-limit function interrupting power at overrun and recovering power supply by inserting the card or by time setting; (7)Disposal function for losing of card, applying for the card at random, with no economic losses to both the Supply department; (8)Si*-digit charaction display indicating both the residual quantity and the code of conditions status in time Two-way metering function accumulating the electric energy of the positive and negative active power at the same direction so as to protect against electricity-theft.Technique index:Manufacturing standard :In conformity to the requirement specified in JB/T8382-96 PrepaymentElectric energy meter standard Accuracy class: Class 1.0,Class2.0; Power consumption: ≤2.0WThree-phase three-wire: 3*100v,50H,3*1.5(6)A,3*(6)A;Three-phase four-wire : 220V/380V,50HZ,1.5(6)A,3 (6),5(20)A,10(40)A,20(80)A .Service conditions :Ambient temperature –20 +50°CRelative humidity: ≤85%
