Three Phase Static Multi-function Energy Meter (CL

1. Summary DSSD/DTSD51 Three Phase Static Multi-function Energy Meter (CL0.2S) is designed according to up-to-date market demands and international metering standards. It can measure positive/negative active/reactive energy and max demand; 4 tariffs; voltage, current and power measurement in real time. It also can monitor and record meter faults, meter reading via RS485 or infrared port. DSSD/DTSD51 Three Phase Static Multi-function Energy Meter (CL0.2S) conforms to: CEI IEC62053-22 Electricity metering equipment (a.c.) Particular requirements Part 22: Static meters for active energy (classes 0,2 S and 0,5 S) equipment 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.)
