  • 230V single-phase or 400V three-phase power supply
  • Integrated and disconnectable RFI filter
  • Front controls
  • Controlled by an external control signal
  • Gas solenoid valve control

Applications:

Gradual control of the speed of a 1-speed three-phase 230/400V or 400/690V asynchronous motor.
Automatic flow rate modulation using an external sensor (temperature probe, hygrometry, CO2, VOC, IAQ, presence sensor).
Constant pressure regulation of a ventilation unit with addition of the VCHV regulator or an external pressure sensor on VFTM only.

230V single-phase drive power supply, 230V three-phase output:
  • VFTE: 6 models from 0.18 to 2.2kW.
  • VFTM Mono: 7 models from 0.18 to 2.2kW.
400V three-phase drive power supply, three-phase 400V output:
  • VFTM Tri: 17 models from 0.37 to 45kW.

Description
  • Frequency converter for three-phase squirrel-cage asynchronous motor (15 to 50Hz).
  • VFTE and VFTM Mono: 230V 50 / 60Hz single-phase drive power supply + earth, 230V three-phase motor output.
  • VFTM Tri: three-phase drive power supply 400V 50 / 60Hz + earth, three-phase motor output 400V.
  • Start / stop + output frequency adjustment by front control; remote control option for piloting from another room.
  • Front display: access to parameters and indication of states and faults.
  • Configurable inputs and outputs:
    • 1 analog input: 0-10Vdc, or 4-20mA signal.
    • 1 analog output: 0-10Vdc, or 4-20mA signal.
    • Programmable logic inputs (start / stop, forced start preset speed).
    • Programmable relay outputs (fault detected, running active, gas solenoid valve control): VFTE = 1 output; VFTM = 2 outputs.
  • Integrated PI regulator.
  • Integrated overload and short-circuit protection (configurable).
  • Compatible with all TT, TN and IT neutral systems (integrated RFI / EMC filter can be disconnected).
  • Protection index: VFTE = IP20; VFTM = IP20 or 21 depending on rating.
  • Integrated Modbus communication.
  • Operating environment -10 to + 40 ° C (at 8kHz); other values consult us.
  • Constant pressure operation: VIM recommends associating the VCHV pressure regulator with the VFTM or VFTE: simplified installation, adjustment and use, clear display of the setpoint and the measurement.
  • These drives have an IE2 efficiency level making it possible to comply with the ERP regulation for electric motors and variable speed drives N ° 1781/2019 applicable since 07/01/2021.
