ATS, UPS & Switchgear

ATS, UPS & Switchgear 

With a Cat continuous power solution, you can protect your critical operations with a full range of power quality and power protection systems. From diesel- and gas-powered generator sets to the Cat UPS, ATS and Switchgear, Caterpillar has everything you need to maintain clean, uninterrupted power for your business operations.

Power Quality Systems 

Continuous power isn’t the only issue when it comes to electrical supply. Even when the electricity is on, the quality of the power can be compromised. Dips, sags and surges create an unstable flow of electricity that can be just as damaging as a complete outage – if not more so – making a clean power supply an equally critical priority. The most common sources of power quality issues are natural causes such as weather, technological issues involving equipment or wiring malfunctions and human error. These issues can create a myriad of problems, including:

  • Loss of critical data
  • Dropped sales or service calls
  • Damage to manufacturing equipment
  • Loss of product or a batch of materials
  • Environmental safety risks
  • Legal liabilities resulting from service lapses

Power Protection Systems 

Business applications that benefit from Cat power protection systems include:

  • Continuous process manufacturing such as plastics, chemicals and pharmaceuticals
  • Information technology providers including data centers, call centers and broadcast companies
  • Critical services including hospitals and emergency response systems
  • Government entities including schools and universities, mass transit systems and public utilities
  • Financial and retail operations such as banks, insurance groups and department stores
  • Companies that would suffer operationally, financially or legally from a power disturbance of any length of time

Uninterruptible Power Supply (UPS) 

Starting with a solid foundation 

All Cat power quality systems begin with a Cat UPS. It provides immediately available power to ride through disturbances and conditions power from the source. When integrated with other Cat products – which include generator sets, Automatic Transfer Switch (ATS) and Switchgear – you can be assured of the cleanest, most reliable source of backup power protection.

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.

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.
