Which Three Phase UPS Family Suits Your Requirements?
Choosing the right three phase UPS system depends on your environment’s size, risk tolerance, and future expansion plans. Here’s how our range supports different operational demands:
Easy UPS 3‑Phase Modular
Best suited for mid-sized facilities where space, cost efficiency, and modular redundancy are top priorities.
Eaton 93PR UPS 25-200 kW
Ideal for small to mid-sized data centres and other mission-critical applications where efficiency, reliability, safety and scalability are essential.
Galaxy V Series
Designed for high-density, scalable infrastructure, suitable for cloud providers, colocation data centres, and universities preparing for rapid digital transformation.
For businesses unsure where to start, Vallous offers consultation using tools akin to a UPS size calculator to help assess load requirements, battery runtime expectations, and lifecycle costs.
When choosing your solution, consider:
- Runtime requirements – Will your loads need extended battery support or generator bridging?
- Power factor and load type – Match UPS output characteristics to the equipment being protected.
- Battery technology – Lithium-ion offers longer life and smaller footprint, while lead-acid provides cost-effective deployment.
- Scalability – Modular or parallel-ready designs support long-term growth without rework.
