Information
The VFVN 100 F frequency converter provides better control of fans in buildings with automatic control. It combines the basic functions of the VFVN 100 frequency inverter with special functions designed specifically for airflow control processes. The frequency converter is available in several frame sizes, with the enclosure meeting IP21/UL Type 1 or IP54/UL Type 12. The power range extends from 0.55 kW up to 630 kW and the devices can be powered from 230 to 500 V. For 690 V supply, the range is from 5.5 kW to 800 kW.
Features and equipment: 1.5-10 kHz
- operating ambient temperature: -10 °C (frost free)...+40 °C
- storage temperature: -40 °C...+70 °C
- painted cards as standard
- braking inverter standard for 3 f, 400 V, from 1.5 kW
- PTC connection: frequency converter must be retrofitted with +SBF4 card or order directly VFVN 100-XX-XX-X PTC set
- EMC: EN 61800-3 Category C2 integrated PID controller
Standard I/O:
- AI (analogue input)
- DI (digital input)
- AO (analogue output)
- DO (digital output)
- RO (relay)
- reference voltage +10 V
- power supply +24 V
- RS-485 (Modbus RTU)
RS-485 and Ethernet buses are integrated as standard. A simple user interface together with intuitive operation simplifies and speeds up commissioning. The operation of the inverter can be optimized using software tools, further streamlining their use. If required, a thermistor input (SEBJ) with ATEX certification can also be used. Specialised software is also available to find the most suitable and economical fan systems.
User-friendly control panel
The frequency converter control is designed to be as simple and intuitive as possible. The control has a clear menu structure that contributes to quick commissioning and trouble-free operation.
- graphical or text-based control panel
- menu in Czech language
- possibility of monitoring up to 9 signals simultaneously
- possibility of setting the number of displayed signals to 4, 6 or 9
- 3 coloured status lights on the control unit: Flashing green - ready; lit green - running; lit yellow - alarm; lit red - error
- graph display for two signals simultaneously
Quick setup
Easy commissioning tools take care of trouble-free commissioning on site. Easy-to-use diagnostics with help are available for every parameter, signal and fault.
- The commissioning wizard allows quick setup of the frequency converter
- The fire mode wizard ensures easy commissioning of the fire mode function
- The application selection simplifies system commissioning
- internal clock supports calendar-based scheduling function
Additional buses
Easy integration into a business automation system is made possible by the built-in Modbus RTU (RS485) and Modbus TCP (Ethernet) protocols. Integration into Profinet IO and Ethernet IP systems is possible via software add-ons. Easily connectable add-on buses facilitate integration into traditional Profibus DP, DeviceNet, CANopen and LonWorks systems.
