Overview:

Multi functional power meters are the new generation of miniature rail type energy meters developed by our company based on years of experience in meter design. This instrument adopts LCD display, which can set parameters such as clock, rate period, etc., and has the function of outputting electric energy pulses; RS485 communication interface can be used to exchange data with the upper computer, greatly facilitating the automation management of electricity consumption. This instrument has the advantages of small size, high accuracy, good reliability, and easy installation. Its performance indicators meet the technical requirements of international GB/T17215, GB/T17883, and DL/T614 for instruments in the power industry.

YN300 Function:

metering
Measure forward and reverse electrical energy, and have automatic recognition and indication of power direction.
The total, peak, off peak, flat, and valley electrical energy are stored separately and saved in the corresponding storage units.
The electricity meter can store data for three months, and the default frozen transfer date for electricity is 24:00 at the end of the month (frozen at the end of the month).
After power failure, all stored data will not be lost and can be maintained for more than 10 years.
Clock and Time Rate
The clock error is within 0.5S/day, and it has automatic switching functions for calendar, timing, and leap year.
Programmable settings for peak, off peak, off peak, and off peak rates, with 8 time slots available per day and a minimum interval of 1 hour between slots.
display
7-bit wide temperature LCD display.
It can display the effective values of voltage and current in real time, and can achieve data rotation display with a cycle display time of 4 seconds.
The electric energy pulse is indicated by a red LED.
The Chinese characters indicate peak, off peak, off peak, and off peak periods for the four middle school rates.
output
Active energy pulse output, used for meter calibration and energy collection.
communication
Used for parameter setting and meter reading.
RS485 communication interface, MODBUS-RTU communication protocol.
programming
Programming settings are performed through the upper computer.
Time and date settings.
Meter address setting.
Rate period setting.
Reset the battery level to zero.
