Single-phase multifunctional power meter is a new generation micro guide rail type energy meter developed by our company, which has accumulated years of experience in meter design. The instrument adopts LCD display, which can set parameters such as clock and rate period, and has the function of outputting electric energy pulses; The RS485 communication interface can be used to achieve data exchange 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, and its performance indicators comply with international GB/T17215, GB/T17883, and the power industry
DL/T614 has various technical requirements for instruments.
Technical indicators
function
metering
Measure forward and reverse electrical energy, and have functions such as automatic identification and indication of power direction.
The total, peak, peak, flat, and valley electrical energy are stored separately and stored in corresponding storage units.
The electricity meter can store data for 3 months, and the default date for freezing and transferring electricity is 24:00 at the end of the month (frozen at the end of the month).
After a power outage, all stored data is not lost and can be maintained for more than 10 years.
Clock and time slot rates
Clock error is within 0.5s/day, with automatic switching functions for calendar, timing, and leap years.
Programmable settings for peak, peak, flat, and valley rates, with 8 daily intervals and a minimum interval of 1 hour.
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. The cycle display time is 4 seconds.
The electrical energy pulse is indicated by a red LED.
Four types of tariff periods are indicated in Chinese characters: sharp, peak, flat, and valley.
output
Active electrical energy pulse output, used for meter calibration and energy collection.
programming
Programming settings are carried out through the upper computer.
Time and date settings.
Setting the address of the electricity meter.
Rate period settings.
Setting the battery level to zero.
signal communication
Used for parameter setting and meter reading.
RS485 communication interface, MODBUS-RTU communication protocol.
Appearance and hole size
Wiring method
Single phase multifunctional power instruments support two wiring methods: primary connection (direct connection) and secondary connection (through current transformer CT connection).
Typical application diagram
Typical application diagram of CNIK100-E/FC
CNIK100-E/FC is a single-phase multi rate active energy metering meter that can be directly connected to a maximum current of 80A. CNIK100-E/FC has a pulse output that can collect the consumption of active electrical energy for analysis using PLC or PC.
In addition, the modular structure facilitates its use with miniature circuit breakers and is installed in the distribution box. The centralization of electricity metering can be achieved through the upper computer.
