DDSH type multi-user external plug-in card electric meter
DDSH1831 Multi User Prepaid Energy Meter
● Product model
DDSH1831-76- □ S+□ D Built in card swiping type
DDSH1831-77- □ S+□ D external card swiping type
● Product Overview
The DDSH1831 multi-user prepaid energy meter achieves prepaid function by recharging and swiping the imported Philips M1 RF card. M1 RF card has no contact, long service life, good encryption performance, stable and reliable operation. This meter purchases electricity first, uses electricity later, and automatically cuts off power after use, greatly facilitating property management, effectively preventing theft and leakage behavior, and solving the problem of difficult charging. It is widely used for electricity metering in residential areas, schools, shopping malls, coal mines, underground garages, and new rural construction.

Main features:
The incoming line of the electric meter adopts a three-phase four wire incoming line.
The outgoing line of the electric meter can be single-phase, three-phase, or a mixture of single-phase and three-phase.
The wiring terminals of the electric meter are all double screw crimped to ensure safe and reliable crimping.
The electricity meter displays the user number and remaining power of each household in a loop, with a loop time of 3 seconds per household.
★ Prepaid function: The electricity meter adopts the function of buying electricity first, using electricity later, and automatically cutting off power when the electricity is used up.
★ Overload control function: When the load exceeds the internal set value of the meter, the meter will automatically cut off power; When it is less than the set value, it will automatically restore power in about 5 minutes.
★ Power outage alarm function: When the remaining power of the meter reaches the set value, the meter will automatically power off, reminding the user to purchase electricity. After inserting the user card, the meter will automatically power on.
The electricity meter is purchased through imported M1 RF cards, which have a long service life.
★ One meter, one card, with the function of writing back meter parameters when swiping the card. The design is rigorous and will not cause electricity disputes.
The electricity meter adopts encryption cards and DES dynamic encryption algorithm, ensuring the security and reliability of system data.
The electric meter adopts a magnetic holding relay as the on/off switch, which has strong overload capacity, sensitive and reliable action.
★ The electric meter has high accuracy, strong overload capacity, stable performance, and low self power consumption.
