Philippines Factory Data Center UPS Project: Dual 60kVA Industrial UPS with 2-Hour Backup
How a factory data center replaced scattered small UPS units with two independent 60kVA three-phase industrial online UPS systems and 128 external batteries to protect critical IT and production data from voltage sags, surges and planned outages.
Power Protection for a Factory Data Center on an Unstable Industrial Grid
The customer's central data center supports far more than office IT. Its servers, MES hosts, storage arrays and core network equipment form part of the factory's production-data infrastructure. When grid quality is unstable, even a short voltage sag can interrupt data processing, trigger server faults or disrupt production-system communications.
The existing arrangement relied on multiple small-capacity UPS units distributed across different loads. As the server environment expanded, this fragmented architecture no longer provided sufficient total capacity, balanced load distribution or the required two-hour emergency runtime.
Voltage Sags Were a Data-Center Problem, Not Just a Grid Problem
The local industrial power environment was affected by recurring voltage sags, lightning-related surges and planned power outages that could last up to 120 minutes.
For a factory data center, these disturbances can affect production servers, MES industrial-control hosts, storage systems, remote equipment monitoring and financial databases. The consequences are therefore not limited to an IT restart: power-quality events can propagate into the factory's wider production and information workflow.
The key requirement: provide stable conditioned power during voltage disturbances while also maintaining enough battery autonomy to bridge a two-hour planned outage.
Three Weaknesses of Scattered Small UPS Units
Insufficient Combined Capacity
As server and storage loads increased, small standalone UPS units could no longer provide a reliable capacity margin for the complete data-center load.
Uneven Load Distribution
Distributed UPS units made it more difficult to organize server clusters into a controlled load architecture and increased the risk of individual UPS overload.
Runtime Was Too Short
The existing battery arrangements could not satisfy the factory's two-hour emergency power requirement during planned utility outages.
Dual 60kVA Industrial Online UPS Systems with Zoned Critical Loads
ShanPu configured the upgrade around two independent 60kVA three-phase industrial online UPS units. Instead of feeding every server and IT device through one mixed power path, the protected loads were divided into zones so that the two UPS systems could support defined groups of critical equipment.
This architecture provides a clearer way to distribute load, simplify capacity management and reduce the dependence on numerous small UPS units.
Conceptual Power Architecture
How Online Double Conversion Helps Against Voltage Sags
A voltage sag is different from a complete outage: the grid is still present, but its voltage temporarily falls below the level expected by sensitive equipment. Servers and network devices can reset or fault even when the disturbance lasts only briefly.
The ShanPu three-phase industrial online UPS uses continuous double-conversion architecture. Incoming AC power is converted and reconstructed before being supplied to the protected load, helping isolate downstream equipment from upstream voltage fluctuations and other grid disturbances.
0 ms Transfer Time
Critical loads remain on the UPS power path without a transfer gap when the input supply fails and battery operation is required.
±1% Output Regulation
Stable regulated output helps sensitive IT and control equipment operate independently of normal upstream voltage fluctuation.
Pure Sine Wave Output
The UPS provides a clean AC waveform suitable for server, storage, network and other sensitive electronic loads.
128 External Batteries for a 2-Hour Emergency Backup Target
Voltage conditioning solved only one part of the factory's problem. The site also needed enough stored energy to keep critical systems operating during scheduled utility interruptions lasting as long as two hours.
| System Element | Project Configuration | Why It Matters |
|---|---|---|
| UPS Capacity | 2 × 60kVA three-phase industrial online UPS | Provides two controlled power zones for the factory data-center load. |
| Battery Quantity | 128 external maintenance-free lead-acid batteries | Extends autonomy beyond the runtime available from small local UPS units. |
| Backup Requirement | Up to 2 hours at full protected load | Designed around the site's planned outage duration. |
| Protected Loads | Servers, MES hosts, storage arrays and core network equipment | Keeps production-data and business-critical systems available during utility events. |
Why This Factory Needed Data-Center-Grade Power Continuity
The protected infrastructure included systems responsible for production-data collection, order archiving, remote equipment monitoring, storage and core network communications.
That makes the data center part of the factory's operational technology environment, not an isolated office IT room. If the server cluster becomes unavailable, production visibility, process information and business-system access can all be affected.
For industrial sites, UPS sizing should therefore account for both IT load and the operational consequence of losing the applications those servers support.
From Fragmented Backup to a Structured Critical-Power System
The upgrade replaced a scattered small-UPS arrangement with a centralized, zoned industrial UPS architecture designed around the actual factory data-center load and the site's two-hour backup requirement.
The result was a more structured power-protection system capable of conditioning unstable grid input, supporting defined server clusters and providing extended emergency runtime during planned outages.

Planning UPS Backup for a Factory Data Center?
A reliable specification starts with more than the server nameplate load. Provide the actual kW/kVA demand, input voltage, backup-time target, battery preference, load growth allowance, redundancy requirement, generator information and known grid-quality issues such as voltage sags or frequent outages.
These inputs allow the UPS and battery system to be sized around the operating risk of the facility rather than around a generic equipment list.

FAQ
Why does a factory need a UPS for its data center?
A factory data center runs production data, equipment control commands, and quality-inspection systems. Grid fluctuations or voltage sags — even a few hundred milliseconds — can crash servers, corrupt data, and halt the entire production line. A UPS with 0ms transfer bridges every grid anomaly so the line never stops.
What is a voltage sag and why is it worse than a blackout?
A voltage sag is a momentary dip or short interruption of grid voltage, lasting milliseconds to seconds. Unlike a blackout (which triggers redundancy plans), a sag is usually unnoticed until servers crash, data is corrupted, and reboots take 30+ minutes — dragging the whole production line down with them.
Why custom 3-phase 220V UPS output?
Standard UPS output is often 3-phase 380V, but many markets — like the Philippines — use 3-phase 220V as the local industrial standard. The UPS's inverter architecture, output transformer, and protection logic must be re-engineered to match the site's grid and equipment, not the other way around.
What size UPS does a factory data center need?
It depends on the load zones. In this project we deployed three tiers — 10kVA units at individual critical equipment/control nodes, 20kVA units at workstation clusters/subsystems, and 70kVA units at main production lines/core server areas — 212 units in total. The right size matches each zone's load class and backup requirement.
Can a UPS handle inductive loads like motors and air conditioners?
Yes — if it is properly engineered. Motor startup draws a high inrush current that exposes weak dynamic response. Ordinary UPS rated for resistive loads can trip into protection mode. This project's UPS ran stably with mixed inductive loads on site, verified under real conditions.
What is factory pre-commissioning and burn-in, and why does it matter for cross-border projects?
Pre-commissioning means every unit is fully tested and parameter-verified at the factory before shipping; burn-in runs the equipment under load for an extended period to expose latent defects. For cross-border projects, engineer visits cost flights, visas, and schedule — eliminating defects before shipping means on-site work is execution only, never experimentation. Zero rework.
How do battery electronic monitors protect a large UPS fleet?
Each battery cell is monitored for internal resistance, voltage, temperature, and health in real time. On a 4,064-battery installation, per-cell monitoring turns "wait until it fails" into proactive warning — a degraded cell is located and replaced before the critical moment, so the backup system is always ready to take over.
How long does a large-scale UPS deployment take on site?
It varies with scale. In this project, battery work alone (unboxing, racking, wiring, testing 4,064 cells) took 10 days, followed by full system commissioning with live load testing. Because everything was pre-commissioned at the factory, the on-site phase ran fault-free and was accepted on the first pass.
