Construction Savings Opportunities
Deployment of the Validus system creates numerous opportunities to reduce equipment, construction and installation costs associated with the critical facility infrastructure. The components used in the alternating current (AC) world are simply no longer required in a direct current power system, yet reliability is improved. Major cost reductions can be achieved from the following:

Mitigation of Equipment Components
When compared to a traditional multi-module AC uninterruptible power system (UPS), a single Validus system can displace up to 5 paralleled AC UPS modules and their associated DC disconnect switches, system static transfer switches, input switchboards and associated controls. When the Validus Power Quality Module can be served from a medium voltage input the need for a medium to low voltage substation which is also mitigated.

With the Validus system, larger battery strings can be used to accommodate the required run times. When compared to a multi-module AC UPS system of comparable run time, Validus can utilize higher capacity batteries within a similar footprint while eliminating one or more battery strings and the associated DC disconnects, spill containment, installation, monitoring, rack, seismic restraint and testing costs. 

Construction & Installation Savings

  1. 1.Mitigation of Equipment Components

  2. 2.Simplified Monitoring

  3. 3.Reduced Installation Costs

  4. 4.Reduced Square Footage Requirements

Reduction of Copper and Steel
Direct current does not suffer from skin effect like AC circuits do. This supports the use of smaller sized DC conductors (approximately 17% less) than comparable AC rated conductors.  This reduction in conductor size drives an equivalent reduction in the conduit sizes used to protect them. The Validus topology also displaces the main UPS input and output feeders yielding a reduction of approximately 15,000 amps of 480 VAC feeder capacity in a typical 4 x 750 KVA AC UPS System. Additionally the DC topology requires only a positive, negative and ground connection, far less that common AC deployments.

Simplified Monitoring
The Validus system has been designed to integrate an advanced monitoring feature set into each discrete system component. This approach eliminates the need for expensive third party add-ons or customized software. Each component of the Validus system communicates with a centralized display through a simple Profinet connection. No additional wiring or data acquisition components are required and it can be readily expanded to integrate additional functionality if desired by the owner.

Reduced installation Costs
Due to the significantly reduced numbers of components required in the Validus system, significant installation cost savings can be realized. A single validus Power Quality Module takes the place of a medium voltage substation, UPS input boards, UPS module input feeders and 5 UPS modules. A single output feeder serves the Validus Power Distribution Module switchboard in lieu of multiple UPS module output feeders. Additional installation savings are attained from the reduction in equipment handling, rigging, installation and the aggregation of battery strings and their associated equipment. 

Reduced Square Footage Requirements
Due to the reduction in the number of required equipment components in the Validus system less total square footage is required to support the power and cooling infrastructure. When compared to a traditional AC multi-module UPS system, space reductions along the order of 30% to 40% can be attained.
