Type DSSF301/DTSF301 Three-phase Electronic Multi-Rate Watt-Hour Meter
General:
Type DSSF301/DTSF301 Three-phase Electronic Multi-Rate Watt-Hour Meter ,adopts advanced special chip for electric power measure and mature multi-rate technique.It uses numeral sampling technology and SMT production treatment.And it is designed and produced according to customer's factual power use,which is among the most sophisticated watt-hour meters
in the word.It realises the function of measure during different periods,setting daily data saving
autpmatically,hand-heal terminal or PC program and meter read.LCDdisplay,ect.It also can set four kinds of rate,ten periods and twelve meter digits.And it has function of electric power impulse output.
Its performance accords with the technique requirements listed in the GB/T 17215-2002" class 1 and 2 static Alternating Active Watt-Hour Meters" and DL/T614-1997 "Multi-function Watt-Hour Meters".The communication regulation accords with the "DL/T645-1997 Multi-function Watt-Hour Meters communication regulation"and communication demands put forward by the users.
