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 converter 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
- standard protection: IP21, optional IP54
- output frequency: 0-320 Hz
- control method: scalar U/f control or speed vector control without feedback
- switching carrier frequency: 1.5-10 kHz
- operating ambient temperature: -10 (frost-free) to +40 °C
- storage temperature: -40 to +70 °C
- lacquered 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 VFVN 100-XX-XX-X PTC set directly

Standard I/O
- AI (analog input)
- DI (digital input)
- AO (analog 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.
A thermistor input (SEBJ) with ATEX certification can also be used if required. Specialised software is also available to find the most suitable and economical fan systems.
