Foley Power Systems understands the importance of high-quality power to your operation. Whether supporting critical processes or defending servers from harmful power problems, Caterpillar UPS systems will provide years of low maintenance protection. With the lowest operating costs in the industry, Cat UPS provides peace of mind as you grow your business.
STARTING WITH A SOLID FOUNDATION
All Caterpillar power quality systems begin with the Cat UPS with flywheel energy storage. The Cat UPS provides immediately available power to ride through disturbances and conditions power from the source. When integrated with other Caterpillar products –which include generator sets, automatic transfer switch (ATS) and switchgear – you can be assured of the cleanest, most reliable source of power protection.

UPS Power Quality & Protection Brochure
Most importantly, the Cat UPS is backed by the solid Caterpillar reputation that comes from more than 75 years of building the best engines and power solutions available. Caterpillar engineers stay on the leading edge of power technology, and you can rely on Stowers every step of the way. Caterpillar sets the standard for single-service support, from extensive parts inventory to preventive maintenance programs, diagnostics and emergency response service.
POWER PROTECTION PLUS
Like other UPS systems, the Cat UPS works by storing enough energy to ride through power disturbances such as dips or surges in voltage and/or current. Match the UPS with a Cat generator set to provide long-term backup during an outage or extended power reliability situation.
What sets the Cat UPS apart is how the power is provided. The Cat UPS uses a highly power dense integrated flywheel to store energy. The stored power is immediately available for delivery to a critical load during a power disturbance. This system provides ample electricity to ride out disturbances or, when paired with a Cat generator set, to allow the engine to pick up the load for a longer backup period. The integrated flywheel design is modular, allowing for easy expansion
to meet future power quality/power protection requirements.
In normal operation, the Cat UPS continuously conditions power from the utility and regulates incoming voltage while using a small amount of energy to keep the flywheel charged. This continues until the UPS senses a power fluctuation. The flywheel then either supplies power to the critical load or consumes electricity from the stored supply to maintain consistent power to the connected load until normal conditions return. The Cat UPS system provides performance that is 97 percent efficient.
THE FACTS ABOUT CATERPILLAR UPS
Caterpillar UPS systems are available from 150kVA to multiple MVA. Consider these facts about Cat UPS systems:
Size and installation. Requires only one-fourth of the floor space of a static UPS system. Maintenance. Requires only minimal upkeep and periodic air filter changes. Reliability. Field-proven mechanical energy storage is predictable and fail-safe. Longevity. Nearly unlimited life with no fall-off in performance. Energy efficency. 97 percent efficient. Temperature. Broad operating temperature range up to 104° F.
MAKING A PERFECT MATCH
Compatibility between UPS systems and standby generator sets can be challenging due to the inconsistency of UPS filters and power electronics. Caterpillar has solved these issues by designing the UPS to work with the generator set from the start. Coupling the Cat UPS with a generator set ensures proper sizing and synchronization. Line noise and generator heating are also less of an issue because the contributed total harmonic distortion is limited to less than four percent. In the event of a full kinetic power discharge, the flywheel can be recharged to 100 percent of energy capacity in less than 2.5 minutes.
LOWERING LIFE CYCLE COSTS
One of the Cat UPS system’s biggest advantages is its lower operating costs over the life of the unit. The Caterpillar system offers less than half the life cycle cost of any battery-based unit. Contributing factors include:
Lower maintenance/replacement costs More efficient management of maintenance resources Space savings of up to 75 percent. Small footprint with no added floor space required for HVAC, temperature control or ventilation equipment Higher system efficiency and reliability Yearly energy efficiency improvement of 4%, resulting in thousands of dollars in savings
PROTECTING THE ENVIRONMENT
By eliminating batteries from the UPS, Caterpillar has created a power quality solution that poses no safety hazards to personnel or the environment. There are no toxic chemicals needed for its operation, no material disposal concerns and no special HVAC or ventilation requirements to address the buildup of heat or harmful/volatile fumes that can be associated with lead acid batteries.
