D7 VIMAC Digital Multifunction Integrated Meter C O N T E N Features T S D7-2 Performance & DIP SWITCH Setting Method D7-4 Connecting Method D7-6 External Dimensions & Diagram D7-8 Certification D7-10 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. ▶ D7 Function to Measure 15 Types 3-Phase Voltage, 3-Phase Current Phase-Phase Voltage Active Power, Reactive Power Active Electric Energy, Reactive Electric Energy Power-Factor, Frequency Communication Function •Communication Mode : RS-232, RS-422/485 •Communication Speed : Maximum 38.4kbps •Connection Mode : RS-232-Point to Point RS-422 / 485-2Wire / 4Wire Multidrop •Protocol : Modbus ▶ VIMAC D7-3 Digital Multifunction Integrated Meter Main Functions Performance Rating Item Connecting Mode Frequency Current Rating Voltage Current Input Range Voltage Operating Temperature Operating Storage Temperature Environment Humidity Control Power Rating 3phase-3wire, 3phase-4wire, single phase-2wire, single phase-3wire 60Hz CT:5A PT:110V AC 0.5A ~ 7A AC 10V ~ 400V -10℃ ~ 55℃ -20℃ ~ 60℃ Less than 80%(No dewdrops form) AC85V~250V/DC85V~155V/DC24V(Option) Measurement Display Range Item Voltage[V] Effective Value Operation Active Power[kV] Effective Value Operation Current[A] Effective Value Operation Active Power[kW] Average Power Reactive Power[kVar] Average Reactive Power Active Electric Energy[kWh] Electric Energy during Measurement Reactive Electric Energy[Varh] Electric Energy during Measurement Power-Factor[PF] Average Power-Factor Frequency[Hz] Average Frequency Display Range 10~9999V 1.000~9999㎸ 0.5~9999A 0.000~99999kW 0.000~99999kVar 0.000~99999kWh 0.000~9999kVarh 0~±100% 55.00~65.00Hz ※Precision on Full Range CT/PT Converting Ratio Setting Item CT PT DIP SWITCH Setting Method D7-4 VITZROTECH Type Primary Secondary Primary Secondary Converting Range 1~50kA 5A 1~345kV 110V Communication Address Setting Switch is displayed in a binary-code and LSB is at the right-end.
