Application

DTS1531J/DSS1531J type three-phase electronic active watt-hour meter (also called watt-hour meter with LCD and RS485 interface) is designed and developed for electric power department or user to monitor the power grid quality, with high accuracy and reliability. The watt­hour meter adopts the advan ced international large­scale integrated circuit of ultra-low power consumption and SMT process. It accurately measures the active energy of three-phase power grid with the reference ratio of 50Hz . It is designed according to the national standard of GB/T 172152002 Alternating Current Static Watt-hour Meters for Active Energy(Classes 1 and 2) and its communication protocol has conformed to DL/T 645 1997 Multi-function Watt-hour Meter Communication Protocol.

Main functions

1 . Energy measurement

It can measure the forward and reverse electric quantity,display the measurement and accumulation of reverse energy and forw art energy, also canindicate the reverse energy amount. Meanw hile,it can prevent the electricity being theft by reversingthe current.

2 . Detection interface

There is a detection terminal of photoelectric isolation and pulse output, for checking the meter.

3 . Communication interface

There is a Rs485 communication interface, conv enience for the centralized meter reading system.

4 . Protection measures

the product intermal design has the protection circuit of resisting the lightning stricke and high frequency electromagnetic interference.

5 . vide range of wor king voltage

In the state of working at 1.5Un over voltage,three luminotrons, represenling phase A, phase B and phase C respectively, indicates whether the phase failure happens, if any phase is failure, the corres ponding indicator lamp goes out.
