UPS Systems

An uninterruptible power supply or a UPS is a system that protects data centers and equipment from temporary power outages and power surges. UPS systems contain a battery backup system that stores incoming AC power for use when your electric power supply falters. Your equipment can then run off of DC power for a short time. Once the power comes back on, the batteries are recharged. Industrial UPS systems protect your servers, computers and other IT equipment from inconsistent voltage that can damage your equipment or cause it to malfunction.

When the electricity goes out completely, UPS systems provide backup power in those crucial moments before your generator kicks in. If your equipment isn’t protected in those few minutes beforehand, it can be costly to your organization, causing you to lose time, money and vital information. UPS systems allow you the valuable time necessary to save information and shut down your equipment, or wait until the generator power kicks in. Interactive Building Solutions installs the industry’s best UPS power supply systems to protect data centers and mission critical facilities.

VFD Service Agreements

What do you want out of a Building Automation project? It could be a high level of technology to sell to tenants. It could be lower operating costs or LEED certification, but without sacrificing performance. It could be greater security.

Whatever your goals are, using IBS in the commissioning process is the best way to make sure you get the project results you need.

Our unbiased expertise gives you an independent, expert assessment of project installation, functionality, training, and service activities. Our work doesn’t add to the scope of the contract.
