Yes, I would like to receive future marketing communications (such as email) from Caterpillar Inc., its affiliates and subsidiaries worldwide and the Caterpillar dealer network. Regardless of whether you decide to receive these marketing communications, Caterpillar will continue to send service/transactional messages, including those that have to do with any accounts that you may have with us.

Overview

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.

    World Wide Product Support

     Cat Dealers provide extensive post sale support including maintenance and repair agreements.  One single service contract for the complete Cat CPM  Cat dealers have over 1,800 dealer branch stores operating in 200 countries.  The Cat S•O•SSM program cost effectively detects internal engine component condition, even the presence of unwanted fluids and combustion by-products

    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 traditional battery 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
