How to use the portable UPS outdoor mobile power supply correctly? The main function of the portable UPS outdoor mobile power supply is to store electric energy. Once the mains power is interrupted, the battery discharges and supplies the inverter. The inverter converts the DC power released by the battery into a sinusoidal AC power to maintain the UPS. How to use portable UPS correctly in our daily life?
Precautions for use and maintenance of portable UPS mobile power supply:
1. Secondary charging must be skillful
After purchasing a new portable UPS power supply, the UPS should be plugged into the 220V power grid and charged for at least 12 hours to ensure that the battery is fully charged. If the UPS is not used for a long time. It should be turned on for 24 hours every 2 to 3 months to make it fully charged, and the UPS power supply should be in the inverter working state for 2 to 3 minutes to ensure the normal service life of the battery. The battery pack charges when the UPS power is turned on. Press and hold the power button for more than 1 second to turn on the inverter.
2. Reasonably choose the installation location
A good installation location is very important. The place where the portable UPS is placed must be well ventilated. Keep away from water, flammable gases and corrosive substances. The ambient temperature should be between 0 and 40°C. The air inlet and air outlet should be kept unobstructed.
3. Install a portable UPS
Pay special attention to whether the order of the neutral wire (N), live wire (L) and ground wire (G) is wrong, and pay special attention to the ground wire. When the system ground fails, do not connect the ground wire to the portable UPS.
4. Pay attention to the safe operation of operators
Safety measures should also be taken when connecting output power to a portable UPS. Since the output voltage and current of the portable UPS are relatively large, you must pay attention to safety when connecting the output power to prevent electric shock accidents.
5. The sequence of power-on and power-off when using a portable UPS
The correct power-on and shutdown sequence should be to first turn on the UPS to supply power to it, and then turn on various loads to avoid damage caused by instantaneous current shock during startup to the portable UPS. According to the shutdown sequence, the load should be turned off first and then the UPS.
6. Avoid overloading with portable UPS
When using a portable UPS, calculate the load size. To avoid overloading or underloading, overloading will cause the UPS to be in an overloaded state for a long time, shortening the service life of the portable UPS. If the load is too small, the UPS working circuit is in an abnormal state for a long time, which is also harmful to the UPS. A reasonable load should be controlled between 50% and 80%.
7. Portable UPS cannot be idle for a long time
For the portable UPS power supply that has not been used for a long time, please let the UPS power supply be charged by the charging circuit in the machine for 12 hours before restarting the power supply. For backup UPS power, it is best to run the portable UPS in reverse every other month. The transformer state works for 2 to 3 minutes to activate the battery.
8. Operation and maintenance
Strictly follow the corresponding power operation procedures during operation. In daily use, all power sockets on the load side of the UPS should be strictly managed; it is best to distinguish them from the power sockets by color or other effective methods. Unused UPS outlets should be turned off or switched off. It is strictly forbidden to connect electrical equipment not related to the computer on the UPS socket, especially high-powered tools.
