Modular UPS power module adopts double-conversion online structure, including rectifier, inverter, charger, control circuit, and disconnect switch of input and output battery bus. With input power factor compensation function. All modules can be hot-swapped online to provide the highest level of availability and maintainability.
A voltage stabilizer may be a simple "feedforward" design or may contain a negative feedback control loop. voltage stabilizers may also use electromechanical mechanisms or electronic modules. According to different designs, voltage stabilizers can be divided into DC voltage stabilizers and AC voltage stabilizers.

Three-in-one-out high-frequency online UPS is widely applicable to the basic equipment needs of users in finance, telecommunications, government, transportation, manufacturing, education, etc...
Modular online UPS is mainly used in data processing centers, computer rooms, ISP service providers, telecommunications, finance, securities, transportation, taxation, medical systems, etc.
When the power supply to the grid is interrupted due to special factors, and the photovoltaic power generation systems connected to the grid are still running and continue to supply power to the grid and the load, this phenomenon is called the islanding effect. Off-grid solar inverters, like photovoltaic grid-connected inverters, have higher requirements for inverters; higher reliability is required; a wider application range for DC input voltage is required.
