DDS3366D single-phase electronic energy meter accuracy: Active 1.0; Storage 12 months historical energy data; based on field environment optional CT21 (50A/10m or 100A/20mA) transformer, if the system current is greater than 100A current selectable polar mutual Scenarios; DL / T 645 protocol, RS485 communication interface. DDS3366D single-phase energy meter rail company is using microelectronic technology and imported new single dedicated LSI, digital sampling technology and SMT technology and other advanced technology research and development phase full electronic energy meter. The table performance in full compliance with national standards GB/T17215-2002 0.5 or related technical requirements a single-phase energy meter can accurately measure directly the rated frequency 50Hz or 60Hz single-phase AC power grid in the active power by 6 +1 digit LCD display total power; has good reliability, small size, light weight, beautiful appearance, convenient installation. Single-phase electronic energy meter functions and features an active energy metering, long-term work is not to adjust 2. Using a dedicated LSI and SMT surface mount technology, advanced technology, simple structure. 3 meter were within the range of 1% Ib ~ 1ma good linearity error. 4. Within meters of all components are made of high quality electronic components, long life and high reliability. 5 Wide operating temperature range of single-phase electronic energy meter Technical Parameters 1 Rated voltage:. 220V 2 basic current: 1.5 (6) A, 5 (20) A, 10 (40), 15 (60) A, 20 (80 ) A, 30 (100) A 3 Rated frequency:. 50Hz 4 Accuracy class: 1, 2 5 Starting current:. 0.4% Ib (1 meter), 0.5% Ib (2 meter) 6 dives. : anti-creep-power logic design 7:. 2W/5VA (machine power) 8 Environmental conditions: standard operating temperature of -30 ℃ ~ +50 ℃ working temperature limit of -40 ℃ ~ +60 ℃ Relative humidity is less than 85% of single-phase electronic energy meter works user's energy consumption by sampling a signal divider and shunt on the circuit to the amplifier and multiplication, multiplication signal by integrating and V / F conversion, then by divider circuit output drive stepper counters and accumulate power, and through the power indicator to show power consumption rate. Single-phase electronic energy meter installation and use 1 meter in front of the factory passed the test, and add seals, you can install and use. 2 meter can be installed indoors or outdoors, floor installation should be fixed in a rugged table refractory wall, recommended mounting height is about 1.8 m, non-corrosive gases in the air. 3. meter meter wiring diagram should be in accordance with the wiring on the wiring box, preferably with copper lugs access. Yueqing Shinco Electric main Camp rail energy meter single-phase, three-phase energy meter track, you're welcome.
