Frequently Asked Questions (FAQs)

  1. What is unity power factor and why does it matter?
    Unity power factor means that 1 kVA = 1 kW; you get full usable power without de-rating. Many UPS units lose usable capacity if power factor < 1.
  2. How long will the battery last under load?
    Runtime depends on load size and battery configuration. The M90LU and M90‑BC options allow extended runtime for high‑uptime applications.
  3. Can I perform maintenance without downtime?
    Yes. Hot‑swappable power modules and batteries plus integrated maintenance bypass allow servicing without interrupting power to the load.
  4. Is the M90U UPS compliant with industry safety and regulatory standards?
    Yes. Certifications include UL‑1778, cUL, RoHS, FCC Class A, and it’s TAA compliant as needed.

What Is a Modular Three-Phase UPS?

A modular three-phase UPS is an advanced uninterruptible power system designed to protect critical equipment from power outages, voltage drops, and surges. It provides three-phase power (commonly 208V or 400V) and features modular architecture, allowing you to scale both power and runtime on demand. This is ideal for dynamic environments like data centers, industrial automation, and mission-critical facilities that require:

  • High power capacity

  • Scalability without downtime

  • Redundant, fault-tolerant design

  • Space-efficient installation

Unlike traditional UPS systems, a modular three-phase UPS allows hot-swapping of power and battery modules, reducing service costs and increasing uptime.

Benefits of Choosing a Modular Three-Phase UPS

Here’s why businesses are switching to modular UPS solutions:

  • Scalable Design – Add or remove modules as power demands evolve.
  • Cost-Efficient – Buy only what you need now; expand later without overhauling the system.
  • High Availability – N+1 redundancy ensures no single point of failure.
  • Faster Deployment – Pre-engineered modules simplify installation.
  • Reduced Footprint – Smaller cabinets save valuable rack and floor space.
  • Simplified Maintenance – Hot-swappable components allow service without shutdown.

The M90U Series is one of the few systems in its class to offer true modularity in a three-phase UPS, making it a top choice for organizations needing maximum flexibility and uptime.

Why Modular Architecture Matters in a Three-Phase UPS System

With traditional UPS systems, upgrading power capacity often requires a full system replacement. In contrast, a modular three-phase UPS like the M90U allows:

  • Vertical scalability: Add modules in the same cabinet.

  • Redundant configurations: Enable N+1 or N+X designs.

  • Rapid serviceability: Swap out failed modules without affecting load.

This is crucial in industries like colocation data centers, financial institutions, and smart manufacturing, where downtime can cost thousands—or even millions—per hour.

Modular Three-Phase UPS vs Standalone UPS Systems

Feature Modular Three-Phase UPS Standalone UPS
Scalability ✅ Scalable in real-time ❌ Fixed capacity
Downtime During Service ✅ None (hot-swappable) ❌ Often requires shutdown
Efficiency ✅ Optimized for load conditions ❌ Lower partial-load efficiency
Redundancy ✅ Easily configured ❌ Harder to implement
Cost Over Time ✅ Lower TCO ❌ Higher service costs

Clearly, a modular three-phase UPS like the M90U is the superior long-term choice for critical applications.
