1 product overview
The DTSY825/DSSY825 three-phase multi-user electric energy meter (hereinafter referred to as the instrument) adopts an advanced single-chip processing system for data acquisition, processing, and storage. Its purpose is to measure active electrical energy with a rated frequency of 50Hz.
Its performance meets the technical requirements of GB/T17215-2002 and GB/T18460.3-2001 standards for three-phase energy meters.
This meter is suitable for ambient temperatures ranging from -10 to 50 degrees Celsius and relative humidity not exceeding 85%.
II main features
Adopting dedicated motor sales management, purchasing electricity first and then using it; Multiple meters and cards in the same area, inserting cards for power consumption, unplugging cards for power outage; It can automatically deduct the amount of electricity used, and when the electricity is zero, it will automatically trip and cut off power; And it has certain anti-theft software design, etc.
The power purchase card adopts SLE4442 encrypted IC card, and each power purchase card has a random password to prevent forgery.
The purchase of electricity card is anonymous; Cannot report loss; Cannot replenish card; Users should keep it properly to prevent loss. The power purchase card can be used repeatedly to purchase electricity within the same area.
Working principle
The electric energy meter obtains the voltage sampling signal from the voltage divider, and the current sampling signal from the current transformer. The voltage current product signal is obtained through a multiplier, and then a counting pulse with a frequency proportional to the product of voltage and current is generated through frequency conversion. The electric energy counting pulse is sent through a photoelectric couplerCPUProcessed and stored in non-volatile storage after computationEEPROMIn the middle. Managed by a computer information system, throughICCard reader/writer, capable of writing a certain amount of power and monitoring requirementsICThe microprocessor system in the card input table, throughCPUAfter calculation, provide display, alarm, and cut-off status signals.
