1. Summary
DSSD/DTSD51 Three Phase Static Multi-function Energy Meter (HF)is designed according to market demands and international metering
standards. It can measure active/reactive energy and max demand in
4 tariffs; record parameters (voltage, current and power etc.) in
real time; and monitor meter faults such as voltage loss and
current loss etc. It also can read meter via infrared or RS485
port.
DSSD/DTSD51 Three Phase Static Multi-function Energy Meter (HF) conforms to:
CEI IEC62052-11-2003 Electricity metering equipment (a.c.) General requirements, tests
and test conditions Part 11: Metering equipment
CEI IEC62053-21-2003 Electricity metering equipment (a.c.) Particular requirements Part
21: Static meters for active energy (classes 1 and 2) equipment
CEI IEC62053-23-2003 Electricity metering equipment (a.c.) Particular requirements Part
23: Static meters for reactive energy (classes 2 and 3) equipment
DL/T614-1997 Multi-function energy meter
DL/T645—1997 Multi-function energy meter communication protocol
2. Functions and Features
