Modular UPS

The modular architecture of a UPS enables a flexible adaptation of UPS power to the needs. The modular UPS system is a scalable solution capable of flexible redundancy. Such as - Vertical redundancy, containing several power modules within the UPS rackmount (N+1, N+X architecture) and horizontal redundancy, expanding several UPS racks in parallel. Creating side-by-side systems also allows for further redundancy such 2N and 2[N+1] architectures. 

Each UPS power module has all the hardware and software needed for autonomous operation; a rectifier, inverter and a built-in controller. Hence, each power module can operate independently, without any need for an external controller giving increased availability.

The power module is hot-swappable which enables a seamless replacement during normal system operation with no impact on the load.  All modules are active and share the load equally.

Each power module has the automatic capability to be the master-system controller so if one module malfunctions, another will take its place without down time or a loss of UPS back up.

In a modular system, each module is lightweight, less than 20kg, enabling easy replacement by a single person.

The modular UPS system is scalable to a higher capacity by simply adding more power modules. This means that as your load grows power modules and batteries can easily be added to increase capacity and run time or to add redundancy. In most cases extra power modules can be installed in a just a few minutes and can even be fitted by the facility support staff, reducing engineering costs and implementation time.

The modular UPS can be equipped according to the current business needs, and in the future to add more power modules. The optimization of this system can significantly reduce the total cost of ownership (TCO).

Modular planning provides a great deal of flexibility in reassembling power to meet changing business needs. Independent components, standard interfaces, and simple operation saves time and cost savings when installing, deploying, reassembling, or moving modular systems.

Modular UPS system's reduce operating costs, especially when factors such as initial transportation and infrastructure costs, spares and maintenance are taken into account.

In addition to reduced costs, the modular approach offers a smaller footprint.

Modular UPS increase availability through superior quality, redundancy, reliability and serviceability.

Deployment Costs of Modular UPS




What modular means for you

Cost Effectiveness Pay for the power you need Often oversized due to limited power granularity Control upfront costs
Redundancy Flexible – achieved also within the system between modules  Limited – achieved only by installing parallel systems Less cost to deploy N+1/N+N redundancy
Footprint Small footprint, high power density Footprint up to twice as big Leave more floor space for income generation
  • Light
  • Only one person needed for module replacement
  • Heavy
  • Forklift needed for system replacement
Cheaper to design and build by avoiding floor stress constraints


Operating Costs




What modular means for you

Energy Costs
  • Sized to fit the load
  • Higher efficiency due to right selection of capacity
  • Designed to work at optimal high-efficiency point
  • Non-optimal sizing
  • Low efficiency due to overpower dimension
  • Operating in a non-optimal  efficiency point causes energy loss
Reduce energy expenses by up to 2%
  • Quick removal/replacement of modules
  • Loads are always protected due to hot swappable modules
  • Less prone to human error
  • User-friendly system controller enables a quick diagnosis 
  • Complex service parts and procedures
  • Load unprotected during service
  • Service can take hours
Easy maintenance saves time and money


Risk Reduction




What modular means for you

Quality Standardized mass production and testing Manual production and testing Reduce number of failures
  • Built using proven, low power components
  • Active current sharing prevents singular hot spots
  • Cooling spread throughout the rack 
  • High power block utilizing specialized components
  • High current and stress on switching elements
  • All heat generated in one place
Increase time between failure
Scalability Quick to deploy when more power is needed Need to add whole new system when loads are increased React fast when you need to deliver more power
