FAQ

 

1. Is a 3-phase UPS necessary for industrial equipment?

Yes. A 3-phase UPS is ideal for high-power equipment such as motors, CNC machines, pumps, elevators, servers, and medical instruments. It provides balanced output, higher efficiency, and stronger overload capability compared to single-phase UPS systems.

---

2. What is the difference between online UPS and offline UPS?

For industrial and IT applications, online UPS is strongly recommended.

3. How do I choose between 10kVA, 15kVA, and 20kVA UPS?

Base your choice on:

• Total load power

• Starting surge current

• Whether loads are nonlinear (motors, compressors, servers)

• Expansion needs in the next 3–5 years

As a rule:
Choose a UPS with 25–30% higher capacity than your current total load.
