An ISO 9001:2008 Certified Company

Variable Frequency Drive

Everyday our frequency inverters prove their high level of cost-effectiveness, reliability, functionality and flexibility in commercial to heavy-industrial applications.

Mitsubishi frequency inverters satisfy all the standards and specifications of the European Union's 2006/95/EC directive on low-voltage equipment and the 2006/42/EG machinery directive. All products have a CE certificate subject to 89/336/EEC, and also UL, cUL and DNV certificates and the certification for the Russian market.

All important protective functions are included as standard equipment, and all Mitsubishi frequency inverters conform to both the ISO 9001 quality standard and the ISO 14001 environment standard.

Energy saving and regenerating frequency inverters

Mitsubishi inverters are real energy savers achieving maximum drive capacity utilisation with minimum power consumption. Flux optimisation ensures that the connected motor only gets exactly the amount of magnetic flux required for optimum efficiency. This is particularly important at low speeds as motors are normally using a voltage/frequency control system. SLV Vector Control with Online Auto tuning and automatic slip compensation, V/f control with a fully-programmable characteristic and Mitsubishi Electric's advanced OEC (Optimum Excitation Control) technology all help to make these frequency inverters masters of energy conservation. They can achieve maximum power savings of up to 60% compared to conventional mains operation, thus minimising system operating costs.

Advanced technology functions like:

  • SLV- Vector Control and V/f Control (fully programmable)
  • Online Auto tuning and automatic slip compensation for outstanding speed stability
  • Soft PWM function for reduced motor noise
  • OEC technology for maximum power savings.
  • Active current limiting (tripless operation)
  • Automatic restart after power failures
  • Flexible control units and intuitive configuration and setup
