Uninterruptible Power Supply (UPS)

Single-phase and Three-phase systems are suitable for a wide range of applications including data centers, telecommunication, retail, healthcare, broadcasting, and industrial.


About UPS Systems

An Uninterruptible Power Supply system, UPS, protects hardware in applications where a disruption of power simply cannot take place.

UPS systems provide a solution for common power problems:

  • Voltage Spikes & Reductions
  • High-Frequency or Oscillation Noise
  • Instability
  • Harmonic Distortion

Common applications that employ UPS systems:

  • Data Centers
  • Telecommunications
  • Process Controls
  • Other Critical Equipment Environments

Types of UPS Systems

Double Conversion/On-Line UPS System

  • Always connected to the inverter
  • In the event of power loss, the system battery keeps power flowing as if nothing happened
  • Once power is restored, the normal system takes over and re-charges UPS system batteries
  • Biggest Advantage: its ability to essentially provide an electrical firewall between the power source and the electronic equipment.

Line-Interactive UPS System

  • A simpler solution to common power problems
  • Offers surge protection and battery backup
  • Allows equipment to be directly connected to the utility power source
  • If a rise fall in normal voltage is detected, the system kicks into place


Single-phase UPS models range from 1 to 22 kVA, while three-phase single module systems range from 15 to 2,000 kVA, and three-phase parallel module systems are available in 80 to 16,000 kVA. All Toshiba UPS systems have a wide range of optional accessory gear available including DC backup solutions, maintenance bypass cabinets, and power distribution equipment.

These End-to-End systems are suitable for a wide range of applications including datacenters, telecommunication, retail, healthcare, broadcasting, commercial, emergency lighting, and industrial.
