Product Name: Three electronic multifunctional electric meters
Number: 111
model: HY-MDSDGN
Product Introduction:
The three-phase electronic multifunctional energy meter is a new type of multifunctional intelligent energy meter designed using advanced technology based on relevant national technical standards, regulations, and the actual requirements of users. It has the characteristics of high accuracy, good stability, reasonable layout, advanced technology, strong practicality, strong functionality, and easy operation. It can accurately and quickly measure and calculate various electrical parameters. The performance indicators of this meter comply with the technical requirements of the national standards GB/T17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters", GB/T17883-1999 "0.2S and 0.5S Static AC Active Energy Meters", GB/T17882-1999 "Level 2 and Level 3 Static AC Reactive Energy Meters", and DL/T614-1997 "Multifunctional Energy Meters" for multifunctional energy meters. Its communication complies with DL/T645-1997 "Multifunctional Meter Communication Protocol" or DL/T645-2007 "Multifunctional Meter Communication Protocol".
Function and characteristic
◆ Time division measurement of positive and negative active power, positive and negative reactive power, as well as reactive power consumption and maximum demand, maximum demand, and time of occurrence.
◆ Phase separated electricity metering.
◆ 4 rates, 4 time zones, 6 time periods, 10 daily time periods, and 12 public holidays.
◆ Voltage and current loss recording function.
3 meter reading cycle data, can automatically freeze data; 12-month meter reading data.
Forward active and reverse active far pulse output, four quadrant reactive far pulse output, pulse width can be set with remote control or RS485.
The infrared remote control retrieves the display item.
During a power outage, the button can be set to trigger display or cycle display. The display items and time can be set using a remote control or software, with a maximum of 25 display options.
◆ - Event records (such as total clearance, required clearance)
◆ Power outage infrared meter reading.
◆ Load record.
To adapt to centralized data collection, it has the functions of instant freezing and timed freezing of electricity, and all data of frozen electricity can be copied out at once.
◆ Overload alarm.
◆ Transformer multiplier can be set.
Display the operating status, various parameter settings, and various measurement data of the electricity meter through LCD liquid crystal display.
◆ - Real time measurement of effective values such as voltage, current, power, and current frequency of phases A, B, and C.
◆ It has event recording functions such as voltage loss, current loss, over power, power outage, incoming call, programming, demand reset, and broadcast timing.
◆ It has programming prohibition function and demand reset function.
◆ It has a power-off button wake-up function.
◆ Two level batteries, one 3.6V battery for data retention and the other two 6V batteries for meter reading, with easy replacement.
