Details:
Dtsd25g three-phase electronic multifunctional watt-hour meter is a terminal product with energy metering which is designed and manufactured in accordance with relevant national standards and combined with the actual demand of power users. The product integrates modern mobile communication (GPRS, CDMA, CSD, SMS, PSTN) technology, adopts mainstream processor, large capacity memory chip, powerful computing ability to fully ensure the realization of complex functions such as electric energy metering, network communication, data storage, data encryption and compression of the field terminal. Industrial grade GPRS wireless communication module is used to adapt to all kinds of harsh operating environment.
It has the functions of measuring positive/reverse active/reactive total energy, four-quadrant reactive energy, split-phase electric energy and recording the maximum demand and occurrence time, and can measure the voltage, current, power, and other parameters of the three phase in real time, and has the functions of monitoring and recording the loss of voltage, loss of current and other faults. And can read through GPRS, infrared or RS485 interface.
The terminal performance index is in line with DL/T614-2007 Multi-function Terminal, DL/T645-2007 Multi-function Terminal Communication protocol, Q/GDW 130-2005 "Power load Management System data Transmission protocol", GB/T17215-2002 "Class 1 and 2 static AC active watt-hour meter" technical requirements.
Functions and features:
1. Time-sharing metering of active and reactive power, with phase-divided metering function.
2. It has 4 rates, 10 time periods, and 4 time zones with a minimum interval of 1 minute.
3. Can measure the maximum demand of active and reactive power, demand period (maximum 60 minutes) and slip time can be set.
4. It can store the data of last month and last month, and the monthly settlement of active power is 12 months 'data, and the settlement date and time can be programmed.
5. Real-time measurement of voltage, current, active and reactive power, power factor and other parameters.
6. The meter has the alarm function of loss of voltage, loss of current and reverse phase sequence, and the loss of voltage, loss of current, voltage qualification rate, programming, clear demand,
7. The meter can be programmed by PC or PDA, with switch and password level control during programming.
8. The LCD screen can be set for automatic wheel display, and can also be displayed by pressing buttons or query data with infrared remote control.
9. With pulse test, 1Hz clock output and demand pulse test port.
10. Electricity meter has independent infrared and RS485 communication interface.
11. Power failure can be used to wake up the electricity meter by pressing the button or infrared, to achieve power failure meter reading.
12. It has the functions of freezing electric quantity immediately, freezing at zero point and freezing electric quantity at hour on the day of load representative.
