3:Product Rationale

 

 

1), Inverter functionThe DC can be converted into AC electrical energypure sine wave outputAdopting the most advanced conversion technology with huge load capacity, high conversion efficiency; It is suitable for commercial, industrial, energy industry, solar energy systems high demand industries;

 

2), High power intelligent charging function :

 

1/ You can choose different types of global battery charge, please check specific product parameters:
Note: Commonly used for maintenance free lead acid battery

2/Charging mode is divided into three sections charge:
Section I: with maximum fast charge constant current to enhance the backup power as quickly as possible.
Section II: getting into a constant voltage of the battery is fully charged , fully absorb the energy to the battery, protect the battery electrodes extend battery life while avoiding overcharging .
Section III: when the full of power in the battery , it will switch to battery float voltage to maintain long time at full power status , and automatically detects battery power, when the charging is completed it could automatically stop working to save electricity.

 

3), With UPS automatic conversion functions

Uninterruptible AC output

Step 1 : When there is electricity , it through the stable voltage and output directly,at the same time, charging for the battery;
Step 2 : When the electricity is switched suddenly, the system automatically changes into the inverter power supply within 4ms, then ensure the load continue to work;
Step 3 : After there is electricity, the system can converted to electricity supply automatically, as well as charging for the battery;  

 

4), Sleep function : When the switch is in the energy-saving mode , Low power consumption,1W6W under sleep state, only the chip at working, the inverter could be automatically cycle detection in a dormant state, when the connected load over 30W, the system will boot into the normal work within the 15S model for load power automatically; when the load is less than 30W, the system will goes to sleep within the 15S automatically ; this function greatly reduces the system unnecessary power waste ;
