DDS854 Single phase electronics watt hour meter

It is used for measuring single phase active energy. good relibility, high accuracy, light weight and specious appearance etc.

1. Brief Introduction

DDS854 single phase electronic watt-our meter is intended for electric energy measurement and registration in single phase two-wire network 

in household. It adopts LSI(large scare integrated circuit), micro-electronics technique and SMT (surface mount

 technology) etc.  Its performance comply with IEC62053-21, IEC 62052-11. 

2. Functions and features

2.1 Front board three fixed hole installation, terminal block is make of bakelite material, which is moisture-resistant, fire-retardant, high temperature overall.

2.2 Way of connection: direct connection, through CT, through CT&PT.

2.3 High accuracy and stability: there is no need to re-calibrate for long term operation. 

2.4 Standard configuration unidirectional 5+1 digits analog register (99999.1kwh), may select LCD or LED display. 

2.5 May extend Communication port, such as RS485, RS232, IR (infrared radiation) etc.
