Feature: 1. The frequency converter is 220v to 380v boost type, and the AC motor is controlled by changing the frequency of the motor's working power supply. 2. Using high-quality core capacitors, chips and IGBT modules, stable performance and quality assurance. 3. Adopts double‑layer board design, reasonable structure, safe, stable and reliable, and the failure rate is greatly reduced. 4. Industrial flame-retardant ABS plastic shell, heat-resistant, flame-retardant and impact-resistant, and has good safety. 5. Adopts all‑aluminum base heat sink, combined with imported powerful fan, super wind power, and good heat dissipation effect.

Package List: 1 x Frequency Converter1 x English User Manual Note: 1. The load of the boost inverter can only be a motor load, and cannot drive other electrical equipment. This inverter does not have a built‑in transformer for boosting. It is only optimized for boosting with a booster circuit and software. It is compact and easy to use. It can be used in situations where there is no industrial three‑phase 380V power supply and the motor cannot be changed to a three‑phase 220V motor by changing the line.2. Type selection①The load capacity of the booster inverter is smaller than that of the ordinary inverter. It is recommended to select a higher level of power. When the motor load is large, it is recommended to select a higher level of power. It is not recommended to use a booster converter for a six‑pole motor.② If the motor can be changed to a three‑phase 220V motor by changing the line, please try to choose a 220V inverter. It can be single‑phase to three‑phase without boosting, and there is no need to increase the power selection. If you can change the line, please ask the electrician or our customer service.3. In order to avoid the customer's own wiring error and burn the machine, the brake unit of the low‑power inverter is now cancelled. If you need to use this function, please contact customer service or leave a comment. The brake unit can be added when shipping. The capital letter B means that there is a braking unit, and the braking function can be realized by bringing your own braking resistor.4. This product is a non‑standard step‑up inverter, which needs to be customized. Two to three days, phase 220v input, three‑phase 380v output, 380v motor can be used without changing the line.5.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
