This type of DCU is an important part of the low-voltage power line carrier (PLC) centralized meter reading system. It uses modern digital communication technology, embedded technology, computer hardware and software technology, low-voltage power line carrier technology etc. to collect, analyze and solve the information of the electricity demand side. It integrates low-voltage PLC meter reading, active reporting, AC analog acquisition, and other functions.
This DCU can easily modify device parameters locally/remotely, supports online upgrade of local/remote software; large-capacity main board FLASH memory chip ensures convenient sotrage of various data; ABS waterproof and flame retardant material, wall-mounted structure, lightweight and easy to intall.
It also has the characteristics of powerful functions, simple use, stable operation, convenient maintenance, high reliability, large storage capacity, good openness and high cost performance. It can well meet the user's application need of monitoring distribution change and remote meter reading, anti-tamper and other aspects.
This type of single-phase electronic multi-tariff prepayment energy meter is an active meter with the data exchange method of numeric medium. The user can load the amount which purchase in advance, make the statement by amount. This meter was equipped with numeric keyboard interface used to active energy metering and prepayment control. Besides, this meter also have infrared communication, RS485 or RS232 communication, metering components, real-time-clock device, load controlling switch and other auxiliary equipment.
This type of three-phase electronic energy meter is the active energy metering meter with the data exchange method of numeric medium. The user can load the amount (quantity of electricity) which purchase in advance, make the statement by amount.
This meter is equipped with numeric keyboard interface used to active energy metering and prepayment control. Besides, this meter also have infrared communication, RS485, metering components, real-time-clock device, load controlling switch and other auxiliary equipment.
And it can achieve the function of metering, anti-tamper, G3-PLC power carrier remote meter reading, GPRS meter reading, RF (radio frequency) meter reading, LCD display etc. Meanwhile having energy testing pulse output function and RTC pulse output.
