There are 3 types:

1. Offline/Standby: This type of UPS protects against power failures and voltage fluctuations only. It is inexpensive and has a simple design, but is no longer widely produced in the market.
2. Line Interactive: This type of UPS is an improved version of the Offline type, featuring an automatic voltage regulation system called a Stabilizer, which helps handle problems more effectively. It is moderately priced.
3. True Online UPS: This is the most advanced and reliable type of UPS, as it continuously receives and converts power, ensuring a constant and clean energy supply. It is highly effective in protecting against all types of power issues but is priced higher.

A UPS is suitable for various types of use, especially where continuous power is essential, and where protecting equipment from power problems is necessary, such as:

1. Data Centers, Servers, and Networks: To ensure continuous operation and service without interruption.
2. Small Offices and Businesses: To protect against data loss and damage caused by power problems.
3. Hospitals and Healthcare Facilities: For critical life-supporting equipment that requires an uninterrupted power supply, such as ventilators.

Generally, we consider the Load that needs protection:

1. Type of Load: If the load is critical, such as a computer server or medical equipment, a True Online UPS should be used.
2. Power Capacity: The size of the power required.
3. Backup Time Required: The duration for which backup power is needed.
4. Manufacturer and After-Sales Service: The reliability of the manufacturer and the quality of after-sales service or support center.

1. Connect the Load appropriately to match the UPS’s power capacity and type.
2. Place the unit in a location with proper ventilation and suitable temperature and humidity.
3. Turn off the unit and disconnect it when not in use for long periods. In case of power failures or fluctuations, keep the AC input cable connected at all times.
4. Perform a discharge test at least once a month to keep the battery in good working condition.

1. In a well-ventilated location with a temperature range of 0 – 40 degrees Celsius.
2. Maintain a distance of 2.5 cm from the sides of the UPS.
3. Close to the Load that needs protection to reduce the chances of overload

• Power failure
• Power surge
• Power drop
• Power spikes
• Brownouts

If the model has an LED/LCD display, it will indicate if there are any faults or errors. If there are no warning lights, fully charge the Load and perform a discharge test by unplugging the AC input.
