Note:

1) The "M" in the specification code represents the current multiple

Example of ordering:

If the customer requires a DDSY606 single-phase electronic prepaid energy meter with a voltage of 220V, accuracy level of 1, current specification of 5 (20) A, LED display, and no 485, the corresponding order code is DDSY606M120M4

The design and structure of the electric energy meter can ensure that it does not cause any danger when used under rated conditions;

The internal circuit board is equipped with relays for direct power on/off control;

Bidirectional measurement, capable of accurately measuring power in both forward and reverse directions, and measuring in one direction;

Purchase electricity first and then use it. If the pre purchased electricity is lower than the set amount, an alarm will be triggered. If the electricity is used up, the power will be cut off;

■Using LCD or digital display to show the usage and remaining battery level;
The meter displayed on the digital tube uses IC card to purchase electricity; LCD displays can be used to purchase electricity through various methods such as IC cards and 485 communication;
The electricity purchase data is encrypted using strict encryption methods.
■ It has alarm and credit functions, with optional alarm and battery credit functions; The LCD display also has an overload and power-off function;
Equipped with 485 communication function, it can read data such as meter number, remaining power, used power, number of power purchases, and last purchased power in the meter;
The LCD display meter can also read the current voltage, current, and power electrical parameters, and can also achieve remote opening and closing control,
The communication protocol complies with DL/T 645-2007 communication protocol.
