When choosing UPS devices, a number of important criteria must be considered, including:

1. Electrical capacity: The electrical capacity required to operate the devices and equipment that is used must be determined, and the UPS must be selected with sufficient capacity to meet the electrical needs.

2. Battery type: A UPS that uses a high-quality and high-efficiency battery must be selected to ensure the continuity of operation of devices and equipment when a power outage occurs.

3. Charging time: You should choose a UPS that charges its battery quickly and has the ability to quickly recharge the battery after a power outage.

4. Size and weight: A UPS must be chosen that matches the size of the space and the required needs, and it must be easy to carry, store and install.

5. Sound: A UPS must be chosen that produces an appropriate sound level and does not cause disturbance to neighbors or workers in the same place.

6. Warranty: Choosing a UPS should come with a good warranty that covers manufacturing issues, breakdowns, and maintenance.

7. Safety: Ensure that the UPS has the necessary safety features, such as circuit protection, overheating and overcurrent protection.

8. Rapid Response: A UPS must be chosen that is characterized by rapid response and immediate operation to provide electrical energy when a mains power outage occurs.

9. Environmental Sustainability: A UPS should be chosen that has energy saving and environmental sustainability features such as automatic stopping when the battery is fully charged.

By choosing a UPS that meets these standards, it is possible to achieve maximum efficiency and safety in its operation, and to ensure the continuity of operation of devices and equipment without interruption in the power supply
