Some manufacturing businesses gradually increase production capacity rather than expanding everything at once.

Modular UPS systems provide flexibility by allowing additional power modules to be installed when required.

Depending on the configuration, they can offer:

– Flexible capacity expansion.

– Redundancy options.

– Convenient module-level maintenance.

– Better adaptability to changing requirements.

This makes them worth considering for growing manufacturing facilities.

4.Industrial-Grade UPS Systems

Manufacturing environments can expose electrical equipment to dust, heat, humidity and vibration.

Industrial-grade UPS systems are designed for demanding applications and may include specialised enclosures, wider operating temperature ranges and industrial communication options.

Always check the manufacturer’s environmental ratings before selecting a system for a particular installation location.

How to Choose the Best UPS for Manufacturing Industry

Selecting an industrial UPS requires a proper understanding of the factory’s electrical requirements. The following factors can help narrow down the options.

1.Understand Your Critical Electrical Load

Start by identifying which machines and systems actually need backup power.

These may include:

– PLC controllers and automation panels.

– CNC machine controllers.

– Industrial computers.

– Monitoring and communication systems.

– Production control equipment.

– Essential safety and instrumentation systems.

Not every machine needs to be connected to the UPS. Separating critical and non-critical loads can prevent unnecessary investment in oversized equipment.

2.Calculate the Required UPS Capacity

UPS capacity is commonly expressed in kVA and kW. Both ratings should be considered when selecting a system.

A basic estimation formula is:

UPS Capacity (kVA) = Total Critical Load (kW) ÷ UPS Power Factor

For example, if the critical load is 90 kW and the UPS has a rated output power factor of 0.9:

90 ÷ 0.9 = 100 kVA.

This provides an initial capacity estimate. The final selection should also consider load characteristics, future expansion, harmonics, transient requirements and redundancy.

3.Decide the Required Battery Backup Time

Different manufacturing processes require different backup durations.

A facility may need only a few minutes to shut down equipment safely, while another may require enough backup time for a generator to start and stabilise.

Consider the following:

– Expected duration of electricity interruptions.

– Generator availability.

– Time required for controlled shutdown.

– Critical production activities.

– Battery replacementand maintenance costs.

Battery runtime should be calculated using the actual load and manufacturer’s battery specifications.

4.Evaluate Power Quality Requirements

Voltage fluctuations, frequency variations and electrical disturbances can affect sensitive equipment.

An appropriate UPS should provide the input and output characteristics required by the connected machinery.

For sensitive electronic applications, online double-conversion technology is often worth considering.

5.Plan for Future Expansion

Manufacturing requirements change as businesses introduce new machinery, increase production capacity or automate additional processes.

Choosing a scalable UPS configuration can reduce the need for major modifications when electrical requirements increase.
