An Online Uninterruptible Power Supply (UPS) is a critical power protection device that provides continuous power to connected equipment by converting incoming AC power to DC and then back to AC. This ensures that the output power is clean and stable, free from fluctuations and interruptions. Online UPS systems are typically equipped with a battery that provides backup power during outages, allowing for seamless operation of sensitive electronic devices.
| Input Voltage Range | 100V to 300V AC |
| Output Power Capacity | 1 kVA to 500 kVA |
| Battery Type | Lead-acid or Lithium-ion |
| Transfer Time | Zero milliseconds |
| Form Factor | Tower or Rack-mounted |
| Operating Temperature | 0°C to 40°C |
When selecting an Online UPS, consider the total power requirements of your equipment to ensure the UPS can handle the load. Look for models with appropriate input and output voltage specifications that match your systems. Additionally, check the battery type and runtime to ensure it meets your backup needs. Certifications such as ISO or IEC standards may also be important for compliance in certain industries. Specify the quantity needed, as bulk orders may influence pricing and availability.
