Details

Air Vents

Equipped with multiple vents and built-in intelligent cooling fans, the frequency drive for single phase motor can keep the temperature inside the inverter stable. An internal cooling fan cools the drive's internal components and forces air circulation to accelerate frequency inverter's heat dissipation.

Aluminum Sheet

The heat sink aluminum sheet of the 7.5 hp frequency inverter for single phase motor is a necessary heat dissipation material, which is used to regulate the internal temperature of the 5.5kw inverter, protect the circuit board from heat damage, and ensure normal operation.

Electronic display of frequency inverter

LED Display

The LED screen of the frequency drive inverter can display the real-time running status to facilitate parameter setting and adjustment, provide alarm and fault information to prevent damage to the frequency drive inverter, and prolong the service life of the 5.5kw inverter.

This frequency inverter does not control the reverse operation of the motor, if you want to reverse operation, please refer to the motor nameplate instructions.

FAQ

What are the practical applications of single-phase inverters?

Home photovoltaic power station: Home photovoltaic power station usually uses solar panels to convert light energy into direct current, and then converts the direct current into alternating current through a single-phase solar inverter to provide daily electricity for the family, and can also reduce electricity bills to a certain extent.
Agriculture and breeding: In agriculture and breeding, single-phase inverters also play an important role. For example, it can provide stable AC power for greenhouses, farms, etc., to meet the power needs of irrigation, lighting, ventilation, and other equipment.
Solar Power Plant: In a solar power plant, a single-phase vfd inverter is used to convert the DC power generated by the solar panels into AC power and inject it into the grid. This application can not only improve the utilization rate of solar energy but also reduce the load on the power grid and achieve sustainable development.
Wind power generation: In wind power generation systems, frequency drive inverters are usually used to rectify and invert the AC power generated by wind turbines to provide stable AC power.
Other fields: In addition to the above application fields, variable frequency drive inverters can also be used in electric vehicle charging piles, uninterruptible power supplies (UPS), and other fields.
