Reliable Power protection for critical applications
The Cat® CONTINUOUS POWER MODULE (Cat CPM) provides constant power protection against
surges, sags, and power interruptions that can disrupt operations or cause loss of valuable data or
system capacity. Caterpillar engineers have designed the CPM for best reliability and space utilization,
and optimized all critical components such as the Generator Set, a high efficient Uninterruptible Power
Supply (UPS) and an Automatic Transfer Switch (ATS) as a complete Cat product.
In the event of a utility power failure, the Flywheel will maintain the UPS output until the generator has
started and the ATS has transferred to the generator supply.

UPS Generator Set Integration
By cancelling harmonic distortion, the UPS operates seamlessly with the generator set to provide a higher
total electrical load capacity without oversizing the generator set. Cat UPS effectively insulates the
generator set from block loads and transient, and can improve its fault clearing capabilities. The CPM is
factory tested and all programmable integration parameters adjusted at factory that assures greater
system reliability and improves the total system operation.
UPS Lower Operating Cost
Caterpillar’s high operating efficiency (>97%) means yearly savings versus many other UPS products.
In addition, lower Cat UPS heat rejection reduces up front HVAC costs and electrical consumption over
the life of the product.
UPS Superior Design
Superior system design and the use of robust digital components throughout the system yield the most
reliable and trouble-free UPS system on the market. Protection is delivered in the industry’s smallest
package with the highest efficiency and superior performance.
Automatic Transfer Switch
A 4-pole, Open Transition Automatic Transfer Switch will switch the load between the utility source and
the generator. It is fully rated to the generator output and incorporates convenient customer connections
for Continuous and Non-critical load. Connection points are also available for load bank testing or a rental
generator set.
