Small drive, big features
July 1st 2006 Mitsubishi Electric has now unveiled three smaller sizes of its F700 series, extending the range from the existing 0.7kW model down to 0.2kW sizes. These new additions allow the rnage to cover virtually every area of industry with options from 0.2kW to 630kW.
The F700 offers a forwardlooking 'Optimum Excitation Control' function. This monitors changes in the load profile and automatically optimises energy usage. These enhanced energy saving features can provide up to 12% extra savings compared with competing products.
Actual energy savings can be monitored via the front panel, which can display the power, percentage or cumulative energy saving in kilowatt/hours or local currency. This information, along with other performance measures can be downloaded via the communication network to a central location.
F700 inverters feature a custom-designed ASIC which boosts performance by reducing speed fluctuations to less than 50% of those measured using conventional drives. This new chip also permits direct display and control of the operating status of the power circuit from the front panel. Further, the F700 continually monitors all aspects its own operation, including key components such as capacitors and protection circuits. More articles from Mitsubishi Electric Europe: |
