Caterpillar Inc. has released a new version of SpecSizer, the popular software tool that helps engineers select a competitively sized generator set for electric power products

Available now for PC users, SpecSizer version 2.7.0 features an optimized 20-Step wizard that automatically calculates the least number of steps for building a load scenario. The 20-Step wizard collects loads, evaluates voltage dip and load demands, and then organizes the loads into steps to help users select a generator set with an optimal rating and footprint that minimizes costs. Along with voltage dip and kVA, the tool now provides an additional method for sizing based on customer-specific frequency dips.

SpecSizer has been updated with technical specifications on several new Cat power systems introduced this year, including generator sets, automatic transfer switches (ATS), switch gear, and uninterruptible power systems (UPS). The latest version of SpecSizer also features Olympian generator sets for markets outside North America, including open generator sets with improved derate capability as well as enclosed units.
