Product Specifications

Technical details and manufacturing context for Uninterruptible Power Supply

Definition
A critical component within an Emergency Power System that instantly switches to battery power during power interruptions, ensuring continuous operation of connected equipment without disruption. It serves as a bridge between the main power supply and backup generators, providing immediate power during the transition period.
Working Principle
Continuously charges internal batteries while mains power is available. When power failure is detected, an inverter converts DC battery power to AC power within milliseconds, maintaining uninterrupted power flow to connected devices until mains power is restored or until backup generators take over.
Common Materials
Lithium-ion batteries, Printed circuit boards, Aluminum heat sinks, Steel casing
Technical Parameters
  • Power capacity rating indicating maximum load the UPS can support (VA/kVA) Customizable
Components / BOM
  • Rectifier/Charger
    Converts AC mains power to DC to charge batteries and power inverter
    Material: Semiconductor components, copper windings
  • Inverter
