Dynamic Cat UPS systems

Uninterruptible Power Source – Dynamic UPS

  • Cat® dynamic UPS systems come in the form of a compact cabinet easily installed close to your sensitive equipment.
  • Ratings from 250 kVA to 1,000 kVA (7,000 kVA in parallel mode)
  • Flywheel energy storage.

Critical power module (CPM) Caterpillar

  • Developed as a containerised solution, Caterpillar’s Critical Power Module (CPM) is a high-efficiency module that can provide uninterruptible power supply of up to 1,500 kVA for critical consumers.
  • A Cat® generator set and battery-free UPS become a seamlessly integrated unit. The Caterpillar CPM is truly a Plug and Play design that meets growing demand for flexible, modular solutions.

Economic investment, low operation and maintenance cost for your equipment:
  • no electrochemical battery (based on a kinetic energy storage system);
  • does not require antiharmonic filter, which is included in the system;
  • saving cost for air conditioning;
  • important space economy;
  • easy to install, low cost maintenance;
  • longlasting and reliable.

  • small percentage of harmonics injected into the grid;
  • unlimited charge / discharge cycles;
  • reduced charging time: 7.5 minutes at first start and within 2.5 minutes after the first discharge;
  • full power operation from -20 to +40 degrees Celsius;
  • easy downstream circuit breaker selection;
  • higher permissible overload.

Operating principles

Cat® dynamic UPS systems can operate alone or integrated with a generator set. Integrating Cat® UPS systems with generator sets guarantees optimal sizing and synchronisation of both systems.When the utility grid is present: it supplies critical load through the filtration system of the Cat ® UPS and allows storing of kinetic energy on dynamic UPS flywheel. Cat ® UPS eliminates any disturbance.
When the utility grid disappears: the dynamic UPS flywheel returns energy instantly to the critical load as an alternating electric current.
When the utility grid returns to normal, Cat ® UPS synchronizes and connects to it, the utility grid resuming uninterrupted critical load supply. Dynamic CAT UPS flywheel recharges.
