DDSU21 M3/M6/M9/M12 single-phase electronic energy meter (rail)

Measure four groups of twelve single-phase circuits using high-precision measurement chips;

Measure the combined active energy, forward and reverse active energy, and combined reactive energy of each circuit;

Store electricity consumption data for 12 settlement days;

Multiple freezing methods: monthly freezing, daily freezing, hourly freezing, instantaneous freezing, etc;

Freeze storage contents: date and time, forward and reverse electrical energy;

LCD display, used in conjunction with buttons, has the function of rotating display of electrical parameters (voltage, current, power, power factor, etc.) of 3, 6, 9, and 12 circuits (channels) respectively, as well as the function of querying and parameters according to menu types;

The sampling current range of each circuit (channel) does not affect each other and can be customized according to the actual needs of customers.
