Product Function Introduction
1.Product schematic diagram
2: Product Principle Description (AC Main Supply / DC Main Supply, selectable via DIP switches on the rear panel)
A. AC Main Supply (AC Priority Mode)
Step 1: When AC power is available, the AC bypass outputs directly, simultaneously charging the battery.
Step 2: In the event of a sudden AC power outage or abnormality, the system automatically switches to inverter power supply within 8ms to ensure continuous load operation.
Step 3: When AC power is restored, the system automatically switches back to AC power supply, simultaneously charging the battery.
B. DC Main Supply (Inverter Priority Mode) (Example shown below using 12V battery mode; other voltage levels are doubled accordingly)
Primarily used for battery power supply; AC power serves as backup.
Step 1: When mains power is available, as long as the battery voltage is above 10.5V, the power supply will output battery inverter power.
Step 2: When the battery discharges to 10.5V, the power supply will automatically switch to mains bypass output, while the mains power assists in charging the battery.
(This function mainly achieves complementary mains power supply to ensure continuous operation of electrical equipment. If mains charging is not needed, it can be disabled on the control panel.)
Step 3: When the mains power charges the battery to 13V through the inverter (or switches to constant voltage mode or float charging mode), the inverter will automatically switch to battery inverter mode output.
Step 4: When there is a mains power failure and the battery voltage is below 10V, the inverter will shut down its output.
If the mains power returns to normal at this time, the inverter will automatically turn on to achieve bypass output while charging the battery.
If the mains power is still abnormal, when the battery charges to 12V, the inverter will automatically turn on and output in inverter mode.
3. High-Power Intelligent Charging Function Description
1) Can charge different types of batteries. Please refer to the product parameters (Section 5 of the instruction manual) for details.
2) The charging method is a three-stage intelligent charging:
Stage I (Constant Current Charging): Uses the maximum constant current for rapid charging to quickly activate the battery and improve backup power.
Stage II (Constant Voltage Charging): Switches to a constant voltage to gradually fully charge the battery, giving it sufficient time to absorb energy, protecting the battery electrodes, extending their lifespan, and preventing overcharging.
Stage III (Float Charging): When the battery is detected to be fully charged, it switches to float charging with a small current and voltage to ensure the battery is at full charge. It automatically detects the battery level and automatically stops charging upon completion to save power.
4. Energy Saving Mode
(Energy Saving Mode Detection Time 5S): When energy saving mode is selected, the power consumption is between 1W and 8W; only the chip is working.When the inverter is in operation, it automatically performs cyclic detection in energy-saving mode. When the connected load is greater than 30W, the system will automatically turn on within 5 seconds to enter normal working mode and supply power to the load. When the load is unloaded (less than 30W), it will automatically enter energy-saving mode within 5 seconds. This function greatly reduces unnecessary power waste of the system and minimizes idle power consumption as much as possible.
