Technical FAQs 4

What is a Megaflex ul uninterruptible power supply (UPS)?

The MegaFlex UL uninterruptible power supply (UPS) merges advanced innovation with reliable power protection. Engineered to be AI-ready, it's the perfect choice for colocation, hybrid, hyperscale and neocloud data centers, ensuring continuous power and security for critical infrastructure.

Is phase selection a problem in a three-phase power supply system?

As observed in practice, phase selection is manually done in three-phase power supply system in most developing countries and this process often leads to power supply interruption which is unhealthy to mission-critical systems.

What is an uninterruptible power supply (UPS) system?

Power distortions such as power interruptions, voltage sags and swells, voltage spikes, and voltage harmonics can cause severe impacts on sensitive loads in the electric systems. Uninterruptible power supply (UPS) systems are used to provide uninterrupted, reliable, and high-quality power for these sensitive loads.

How powerful is a 3 phase UPS?

With the advent of the new hyperscale data centers, sizing a three phase power supply has changed. 80-750 kVA UPS products are now considered medium and are commonly, but not exclusively, utilized in medium size, or edge data centers with a 1-5MW load range. Small is powerful with the 10-80 kVA three phase UPS models from Mitsubishi Electric.
