summary:

DDSH5999 can measure up to 39 households' single-phase electricity consumption or 13 households' three-phase electricity consumption. It has forward metering, no power outage function, and cyclic display of electricity consumption information for each household. It is centrally installed and easy to install. It can be read by infrared meter readers or remotely by computers through networking, making it easy for management departments to timely grasp and summarize monthly electricity consumption information. The product complies with JB/T10451-2004 (Special Requirements for Multi User Static AC Active Energy Meters) and GB/T17215321-200B (Level 1 and Level 2 Static AC Active Energy Meters) standards. The product is widely used for electricity measurement in enterprises and institutions, urban residential areas, student apartments, old building electricity meter renovation, high-rise buildings, etc

characteristic:

By using encryption cards and DES dynamic encryption algorithm, the system data is secure and reliable.

Adopting high-power magnetic holding relay, it has strong overload capacity, sensitive and reliable action.

The function of writing back the meter parameters after inserting the card is designed rigorously and will not cause any electricity disputes.

High precision, stable performance, low self power consumption, anti-theft, no need for calibration for long-term use.

When the remaining power is low, a power-off alarm (can be set) is triggered to remind users to purchase electricity in a timely manner.

Load control function: When the load exceeds the set value, the electricity meter will automatically cut off power. After the load decreases, the electricity meter will automatically restore power supply in about 5 minutes.

This function can also be added if remote control through networking is required.
