Detailed Product Description
Model:
DTS(X)855 3-Phase 4-Wire active & reactive combination kWh meter
DSS(X)855 3-Phase 3-Wire active & reactive combination kWh meter
1.Purposes
3-Phase electronic active & reactive combined Kilowatt Hour Meter with high accuracy and reliability. It adopts international advanced low energy consumption large-scale IC and SMT Technology, all key components are of international famous brands with long service life, which prolongs service life of product greatly. It is capable of precisely measuring active power and Reactive power with rated frequency of 50 Hz or 60Hz in 3-Phase Power Supply Network, and replacing two common 3-Phase Kilowatt Hour Meters. The product is in accordance with all technical requirements in GB/T17215-2002, GB/T17882-1999 and DL/T645-1997 for 3-Phase electronic Kilowatt Hour Meter.
2. Functions and features
2.1 with standard RS485 port can transfer data in long distance. Can communication with PC by RS485, the communication protocol and data structure confirm to DL/T645-1997 standard, baud rate is 1200bps.
2.2 with active pulse and reactive pulse output, the pulse width is 80ms±20ms.
2.3 can measure active energy consume (kW.h) and reactive energy consume (kvar.h)
total active energy (kW.h) =positive active energy + reverse active energy;
total reactive energy (kvar.h) =positive reactive energy + reverse reactive energy.
2.4 3-Phase power supply. When 1-Wire (any one line in 3-Phase & 3-Wire Kilowatt Hour Meter) or 2-Wire (any two wires in 3-Phase & 4-Wire Kilowatt Hour Meter) is cut off, measurement accuracy still is ok
2.5 adopt advance energy meter integrate circuit, the data is saved in storage forever, lose voltage not lose data.
2.6 with phase-cut indication function. (for 3phase 3wire meter if Phase Ub is cut without indication)
2.7 Wide working temperature range;
2.8 High accuracy, active is class 1, reactive is class 2
