Toshiba Variable speed drive series VFS15 has been replaced by VFS15


  • Latest drive available in this kilowatt range
  • Compact
  • Extends the features offered by previous drives
  • User friendly
  • Easy to program
  • Compact size
  • High ambient temperature withstand
  • Front mounted potentiometer

The global standard inverters

  • The Tosvert VFS-11 meets major global standards: UL/CUL, CE and C-tick.

Wide input voltage range

  • Single three phase : from 200V to 240V
  • Three phase 200V class: from 200V to 230V
  • Three phase 400V class: from 380V to 500V

Switchable interface logic

  • The VFS-11 has a switchable control logic interface, a source logic (European type) or a sink logic (US/Japan type). It offers programmable terminal functions for assigning suitable functions to each terminal

EMI Noise filter inside

  • The three phase 400V class and single phase 200V class install EMI noise filters to meet EMC directive.


  • A large potentiometer makes it simple for anyone to adjust output frequency
  • There are four automatic setting functions for easier operation. (Acceleration/deceleration time, V/f control mode, condition and terminal assignment)
  • The VFS11 allows side by side installation to minimise the space required
  • Sensorless vector control gives low speed start up torque of over 150% of the rated torque
  • The VFS11 detects inverter input and output phase failure


  • Communication converter unit (RS485/RS232C)
  • Extended panel/parameter writer
  • IP43 enclosure/NEMA type 1 kits
  • DIN rail attachment (for 200V class 0.2 to 0.75kW)
  • Foot-mounted filter (EMC directive: For class B and class A)
