IV. What should the UPS power rating be?

Power in UPS devices is a key parameter that defines the device’s ability to maintain power to connected loads during an outage. It is expressed in two units: kVA (kilovolt-amperes) – apparent power, and kW (kilowatts) – real power actually used by the equipment. The real power rating depends on the Power Factor (PF), which for most UPS units ranges from 0.6 to 1.0
EXAMPLES 💠A 5 kVA UPS with PF 0.6 delivers a maximum of 3 kW of real power💠 💠A 5 kVA UPS with PF 0.8 delivers a maximum of 4 kW of real power💠 💠A 5 kVA UPS with PF 1.0 delivers a maximum of 5 kW of real power💠
The UPS power rating should be selected based on the sum of the maximum power of the devices you want to support during an outage. It is a good practice to include a power margin of 20–30% above the total connected load to prevent overloading. When choosing a UPS, also consider equipment with high inrush current requirements—like servers, air conditioners, or pumps—which require a UPS with a higher apparent power rating (kVA) and a pure sine wave (PSW) output for reliable operation.

V. Three-phase or single-phase UPS?

Three-phase UPS and single-phase UPS are power protection devices that differ primarily by the number of phases they handle, affecting their applications, design, and performance. UPS selection should consider the specifics of the electrical installation and power demand. Notations like UPS 3:1, UPS 3:3, UPS 1:1, and UPS 1:3 refer to input-output phase configurations in UPS systems. Below is a detailed comparison:

Input: Single-phase supply (230 V).
Output: Single-phase output (230 V).
Application: Most common for homes, offices, small server rooms, PCs, and office equipment.
Example: Protecting a PC or home router.

3:1 or 3/1
three-phase input, single-phase output

Input: Three-phase supply (400 V).
Output: Single-phase output (230 V).
Application: Used when three-phase power is available but only single-phase protection is needed.
Example: Protecting single-phase equipment in larger industrial or office installations.

3:3
three-phase input, three-phase output

Input: Three-phase supply (400 V).
Output: Three-phase output (400 V).
Application: Protects three-phase loads like motors, cooling systems, large data centers, or industrial machinery.
Example: Large server rooms or industrial infrastructure.

1:3
single-phase input, three-phase output

Input: Single-phase supply (230 V).
Output: Three-phase output (400 V).
Application: Rare, specialized solutions requiring generation of three-phase output from a single-phase source.
Example: Experimental or specific industrial applications.

How to choose the right configuration?

1:1 – For individual devices and simple applications.
3:1 – When you have three-phase input but need single-phase protection.
3:3 – For large industrial installations, data centers, and three-phase loads.
1:3 – Very rare, for non-standard systems.
