Трехфазный статический многофункциональный счетчик энергии (ВЧ

1. Summary DSSD/DTSD51 HF Three Phase Static Multi-function Energy Meter 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 HF Three Phase Static Multi-function Energy Meter 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.)
