From diesel and gas generator sets to uninterruptible power supplies, automatic transfer switches and electrical switchgear, we'll help you build an integrated independent energy solution to your specifications.

HOLT® CAT Power Systems offers reliable, independent energy solutions when utility power is unavailable or impractical. With power options from 12 kW - 17,460 kW CAT® industrial engines offer the widest power range in the industry.

Our in-house project engineers/management team provides complete specification and installation consultation, working directly with electrical contractors and engineers, supplying the information needed to complete projects on time and within budget.

TOTAL SYSTEM INTEGRATION

All Cat products are designed to work together, with all elements relating to the generator set production, control and monitoring function integrated into a single-source package.  You’ll also have the benefit of a single source for parts and service. HOLT is always available to provide the support you need, from system design to long-term maintenance.

Generator Paralleling Switchgear

This advanced family of generator control switchgear products provides paralleling and load management for Cat products and is an integral part of any electric power solution.  Cat switchgear provides a seamless integration with Cat generator sets and is available in single-standby to load management to multiple/utility paralleling configurations from 600-volt class through 15kV to create a harmonized system solution.

Automatic Transfer Switch (ATS)

Caterpillar offers a broad range of ATS products, with digital microprocessor controls, to suit any application – from a single ATS installation to a complex multi-ATS/generator switchgear system. Both open and closed transition designs are available with optional bypass/isolation and delay features in sizes from 40 to 5,000 amps.

Uninterruptible Power Supply (UPS)

Whether your application is suited for Flywheel UPS or Double Conversion UPS, you can expect the reliable backup power you depend on. Your Cat system continuously conditions power and regulates voltage from the source, and provides ride-through power to bring the generator set online.

It provides precision voltage regulation, fault tolerant output, user-friendly interface, good generator to UPS sizing ratio and reduced installation costs.
