Smooth speed adjustment, with excellent performance at low speeds.
2. Variable frequency drives are generally suitable for operating temperatures ranging from -10℃ to 40℃, with humidity levels below 90%. When the environmental temperature exceeds 40℃, the drive should be derated by 5% for every 1℃ increase. For every 10℃ rise in temperature, the lifespan of the drive is halved. Therefore, it is crucial to address the issues of surrounding environmental temperature and the drive's heat dissipation.
All power products, including variable frequency transformers and voltage stabilizers, should be kept away from fire sources and high temperatures to prevent excessive heat.
4. Prevent oil mist and salt from corroding variable frequency power supplies.
Please place the variable frequency power supply in a well-ventilated area, ensuring it is at least 30 cm away from other objects to maintain proper ventilation of the intake openings. Aviation ground power supply 2, 36V aviation power supply 1, 400Hz variable frequency power supply 7, 115/200V power supply 2, 27V DC power supply 5, 400Hz power supply 12, aviation power supply.
6. The normal operating environment for the variable frequency power supply is a temperature range of 0℃ to 40℃, and humidity of 0% to 90% (non-condensing state).
7. Avoid placing variable-frequency power supplies in areas with corrosive gases, vibration, and magnetic field interference.
Avoid placing the variable-frequency power supply in direct sunlight, under rain, or in a damp area.
Do not place 60Hz power, 400Hz power, and other various power supply products on uneven or inclined surfaces.
10. When variable-frequency inverters drive standard motors, compared to power frequency sources, there will be an increase in losses, a decrease in cooling effect at low speeds, and an increase in motor temperature rise. Therefore, the motor's load torque should be reduced at low speeds. When the motor operates at high speeds (above 60Hz), there will be changes in electromagnetic balance and bearings, etc.
