The single-phase 220V to three-phase 380V inverter adopts the AC-DC-AC circuit structure and uses SPWM modulation control technology to convert the ordinary single-phase 220V power to industrial three-phase 380V power. It is suitable for three-phase asynchronous motors with an output phase angle of 120°, which fully meets the standards for motor use and is suitable for various types of motor loads. The single-phase electric variable three-phase electric frequency converter solves the inconvenience caused by the three-phase electric power limitation in some areas, and also solves the user needs that cannot apply for the three-phase electric power due to site restrictions.
1. Technical characteristics:
· 220V input for ordinary city power, eliminating the cumbersome procedures for applying for three-phase power and various labor costs and various hidden costs
·The output uses industrial three-phase electricity, but it is charged according to civil single-phase electricity, which is economical
·The core components are all imported devices with stable performance and long service life
·Safe and reliable, the input single-phase electricity is completely electrically isolated from the output three-phase electricity
·The input wide voltage range is designed to adapt to the working environment with low mains voltage in various regions
·Perfect output protection function, with multiple protections such as overvoltage, overload, overtemperature, short circuit, overcurrent, etc.
·The single-phase 220V drive of the boost converter can be soft-started to drive the three-phase 380V asynchronous motor without the need for industrial three-phase 380V electric drive
·The output phase angle of the boost converter is 120°, which fully meets the motor use standards and is suitable for various types of motor loads.
The input frequency of the boost converter is 50/60HZ, and the output frequency is adjustable 0-650HZ
2. Matters needing attention:
·The step-up frequency converter belongs to the capacitance step-up. For the load, it is used for light-loaded sites below 22kw. In terms of type selection, the light-loaded motor is selected as a large-level inverter, and the heavy-loaded site is selected as a large-level Inverter.
·The boost converter can only be used for three-phase asynchronous motors, not as a power supply.
·The booster inverter is not suitable for the scene that needs to start and stop quickly, and the occasion of potential energy load.
