Electronic Three-Phase Prepaid Electric Meter (DTSY833 series)

Product Description

DTSY833 Series electronic three-phase payment meter

Application
Type DTSY833 three-phase electronic prepayment electric energy meter is the instrument controlling the electricity by limiting the quantity and load after the user pays the energy change to the supply department in advance. It employs the American chip it measure the impulse as well as the latest encrypted IC card to transmit the data. With one card for one user, it is provided with the function for protecting against electricity-theft. Therefore, it is widely applied to industrial or mineral enterprises, real estate management of small residential area, and town and country network reform.
Each of the performance indexes is strictly in conformity to the technical requirements for electronic three-phase prepayment electric energy meter specified in IEC 1036and JB/T8382-96 standards.

Main functions&characteristics
(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 operation wtatus;
(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)Six-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.
