Overview
The DJSF866 electronic single-phase multi rate DC energy meter is a new generation of intelligent high-tech energy metering product developed and produced by our company. It is based on dedicated metering chip technology and adopts the latest integrated circuit technology. It is designed and manufactured according to relevant international (IEC) standards for electric energy meters and China's power standards DL/T614-2007 "Multi functional Electric Energy Meter", DL/T645-2007 "Multi functional Electric Energy Meter Communication Protocol", JJG 842-1993 "DC Electric Energy Meter Verification Regulations", etc. It integrates measurement, monitoring, alarm, display, freezing, RS485 communication, and infrared communication functions, realizing DC measurement of charging piles and collection and storage of electricity information.
Basic functions
1. It has positive and negative active energy metering functions, with time-sharing metering function, and can store monthly electricity data.
2. Multi rate function
2.1 Adopt a built-in hardware clock circuit with temperature compensation function, which has calendar, timing, and leap year automatic switching functions. The output frequency of the internal clock terminal is 1Hz.
2.2 It has 2 sets of time zone tables and can be configured with 2 sets of time zone table switching times;.
2.3 It is possible to configure public holiday periods, and it is also possible to configure the schedule number for selecting weekends and weekends.
3. Measurement and monitoring: capable of measuring voltage, current, active power, etc. The measurement error (citation error) shall not exceed ± 1%.
4. Communication function: The communication protocol complies with the requirements of DL/T645-2007 and its filing documents.
5. LED indication and pulse signal output.
6. Meter sleep: When the external AC power supply is cut off, the meter is powered by the internal battery to maintain uninterrupted operation. At the same time, the meter automatically enters sleep mode to reduce battery power consumption; When the external AC power supply is restored, the electricity meter exits sleep mode. Can be awakened in sleep mode.
7. Data freeze: with the function of recording the active historical electricity of the previous 12 months
