Overview:

DDZY637C single-phase local cost-controlled smart energy meter is an intelligent energy metering product developed and produced by our company, which is suitable for the measurement of single-phase AC active energy with a rated voltage of 220V and a frequency of 50Hz. It has an independent modulated infrared optical port and one RS485 communication port; it has an IC card port, which can support the function of local cost control; the watch has the advantages of high reliability, high precision, and long life. It adapts to a wide voltage range, and the whole machine does not need to be adjusted after leaving the factory. It can be widely used in the measurement of single-phase alternating current in cities, rural areas or factories.

Features:

Electric energy metering: It can measure positive and reverse active energy, and has the function of time-sharing metering;

Display function: LCD automatic wheel display or manual button display to display various information such as power, voltage, etc. The display content can be set by programming:

Measurement and monitoring: can measure, record, and display the current operating parameters such as voltage, current (including neutral current), power, power factor, etc. of the current electric energy meter;

Rates, time periods and electricity price schemes: There are 2 sets of rate timetables, at least 4 types of rates are supported, and 2 sets of electricity price schemes can be automatically converted upon request:

Power freeze: It has functions such as timed freeze, instant freeze, appointment freeze, daily freeze, and hourly freeze;

Event record: It can record events such as reset, programming, power failure, switch on and off, and cover opening;

Communication function: with infrared, RS485 communication:

Local cost control function: Set the power consumption parameters of the electric energy meter through the CPU card to realize the control function of the electric energy meter:

Alarm function: When there is a fault in the meter, the meter will display the fault code and alarm.

Power failure meter reading: press the button to wake up the LCD display, and can read the meter through infrared.

Scope of use:

220V 1.5(6)A-20(100)A Imax/lb≤12, suitable for modern residential and urban users, after networking, it can realize remote cost control function.
