DDSF 855 Type Electronic Single-Phase Multi-tariff Kilowatt Hour Meter
1. Summary
1.1 DDSF 855 Type Electronic Single-Phase Multi-tariff Kilowatt Hour Meter, is used to measure 50 Hz single-phase AC active power consumed in different periods (Power consumption of total, keen, peak, normal, valley tariff). Its performance is in accordance with all relevant technical requirements in GB/T17215-1998 "1-Grade and 2-Grade Static AC Kilowatt Hour Meter" and GB/T15284-1994 "Multi-tariff (Time division) Kilowatt Hour Meter", and its data communication protocol is in accordance with all relevant technical requirements in DL/T645-1997 "Multifunctional Kilowatt Hour Meter Communication Protocol".
1.2 Characteristics: LCD display, long service life, highly accurate, good overloaded performance, low power consumption, co***ct. A special real-time clock chip is used to ensure reliability of timing data. Infrared communication interface or 485 communication interface (optional) are used to set functions and read meter etc.
