management machine
——General Information——
Product Features:
1. Adopt flame-retardant shell, light in size and easy to install
2. Collect real-time energy indication value of each energy meter, daily zero-point frozen energy indication value, meter reading day zero-point frozen energy indication value
3. The meter reading scheme can be set and inquired remotely or locally
——Product Function——
1. Data collection
The concentrator collects the real-time energy indication value of each energy meter, daily zero-point frozen energy indication value, and meter reading day-zero frozen energy indication value. Energy data should be saved with a time icon.
2. Data storage
The concentrator can classify and store the collected data as required, such as daily frozen data, meter reading daily frozen data, curve data, historical monthly data, etc.
3. Event record
The concentrator is divided into important events and general events according to the set event attributes. Events include terminal parameter changes, meter reading failure, terminal power off / on, energy meter clock out of tolerance, etc., and can save the latest 500 event records.
4. RF card function
Can correspond to any user to support remote encryption recharge or refund.
