Detailed Product Description

DDS686 single phase electronic energy meter (LCD display) is a full electronic energy meter to measure the single-phase AC active power at 50Hz or 60Hz.

Certificates

DDS686, Single phase energy meter, class 1,

 220V, 10(60)A, 50Hz

The energy meter fulfills the requirements mentioned in IEC61036 Alternation current static watt-hour meters for active energy (classes 1 and 2), requirements for class 1 and indoor use.

The results of the type test are mentioned in KEMA report with reference number 2018548-QUA/CAL 02-1688.

This product conforms to GB/T 17215.321-2008 standard.

Functions and features

1    Use imported chips with high precision which could precisely calculate active two-way power;

2    With reliable start-up and creep performances;

3    All meter lines are supplied with transformer power, which greatly improves the stability and service life of the meter;

4    With the protection from the harmonic wave and high-frequency pulse interference;

5    With protection measures against power grids interferences (lightning) ;

6    Shows a number of recycled information (including electric quantity, constant, meter number, etc.);

7    Using broad-temperature LCD which could display normally between the temperature from -30^oC to 70^oC;

8    While Communication configuration, it can be through infrared or RS485 interface to read meter information (including electric quantity, constant, meter number, etc.), with stable communication performance and 100% of the success rate of meter reading;

9    When the LCD is equipped with clock configuration, the meter has clock's function, with high precision when it is powered by inside battery. It can block electricity according to the user's configuration, preserve the current electricity and the frozen electricity data of the past 12 months. It can record the reverse electric quantity and its starting and ending time of the last three times. It can also record the programming content and time of the last three times. It is facilitated with power indicator light. When the meter has the power, the light turns on. The installation sizes are in accordance with DD862 Single-phase mechanical meteres, with full transparency of the upper cover and elegant appearance;

10It can be formulated according to customer demand of infrared or RS485 communication type, clock type, or relay-controlled type.
