Variable Frequency Drive
0.75 KW to 355 KW
1. Energy Saving with Inverters
The consumed power of a variable-torque load, such as fans, pumps and blowers is proportional to the cube of its rotation speed.
Adjusting the air volume by the inverter rotation speed control can lead to energy savings.
[Example of blower operation characteristic]
Utilizing the motor capability to the full
Optimum excitation control
Optimum excitation control continuously adjusts the excitation current to an optimum level to provide the highest motor efficiency. With a small load torque, a substantial energy saving can be achieved. For example, at 4% motor load torque for a general-purpose motor, the motor efficiency under Optimum excitationcontrol is about 30% higher than the motor efficiency under V/F control.
Improving starting torque and saving energy at the same time
2. Protected in Hazardous Environments
Special-purpose inverters with circuit board coating (IE60721-3-3 3C2/3S2) and plated conductors are available for improved environment resistance.
For the details, please contact your sales representative.
3. Global Compatibility
The F800 series inverters are compatible with UL, cUL, EC Directives (CE marking).
Being RoHS compliant, the FR-F800 inverters are friendly to people and the environment.
