Digital Multifunction Integrated Meter _ Feature
VIMAC - Ⅲ
VITZRO TECH VIMAC Series are the digital multifunction integrated meters that can monitor various
measurement elements so as to handle the electric power systems which change in a more complex way.
D7-2
VITZROTECH
Features
It is an inexpensive Non-Display Type meter with the optimal effects with the minimum basic
specifications.
Thus, it is easy to check all the measured values through a communication and it can compose a full
electric power monitoring system via a high-speed data communication.
It is possible to measure 3-phase voltage, phase-phase voltage, active power, reactive power, active
electric energy, reactive electric energy, power-factor, frequency and so on and display them by the
communication. It is optimized to arrange an electronic panel since the product is reliable and easy to
assemble.
RS-232 communication and RS-422/485 communication are possible and it uses Modbus protocol
communication mode. Therefore, it is an advantageous product in terms of the economical aspect and
the functional aspect.
•Measurement of 15 types with 1 device
- It is a Non-Display Type and uses a console to display 15 types of measurements via the communication.
- It saves space when compared to the analogue meter that has only 1 function and it is easy to connect.
•Simple Adjustment & Setting
- It is easy to adjust CT/PT converting range, communication ID and communication speed by
binary-coding the front DIP SWITCH.
- All measurement parameters can be set using the console and it is easy to check the set value
and measured value.
•Various Communication Network Composition
- Using a general Modbus Communication, it is possible to build an upper system and network and
measure and monitor in remote. It is highly reliable.
- It is highly compatible for it can use both RS-232 Serial Communication and RS-422/485 Communication.
