UPS Products

Whether safeguarding critical data, sustaining operations during power outages, or ensuring seamless connectivity, having an uninterruptible power supply to safeguard against voltage and frequency disturbances and provide back up power in the event of mains failure is crucial in today’s digital age. At its core, a UPS system is the guardian against power disruptions, when your primary power supply wobbles or fails it ensures that your critical equipment, services and infrastructure can keep on working.

UPS systems come in various types, each offering different levels of protection and efficiency. Single-phase UPS systems are designed to provide power backup for smaller applications and individual devices.

Three-phase UPS systems are engineered for applications such as server rooms, data centres, hospitals and commercial buildings where the feed is a three-phase power supply, replacing mechanical, rotating cylinder (rotary) UPS in almost all applications, most three-phase systems nowadays tend to of the static (i.e. based purely on electronic processing) online double conversion type, though there are three main architectures.

Three Main Architectures

Replace with Standalone, Modular and Semi-modular:

• Standalone UPS: Standalone (also known as monolithic) three phase UPS systems have one of each main components of a UPS, all together in a single unit.  They are used where no redundancy is required or where a user wants separate, complete, full capacity systems on different feeds i.e. N+N redundancy.

• Semi-modular UPS: Semi-modular UPS units share some components internally, such as a charger or static switch, and replicate others across modules. This offers a degree of scalability for future expansion and potentially some efficiency savings by enabling surplus modules to be put into standby if the load drops. However, as they share single points of failure the modules do not truly increase redundancy.

1. Battery: The heart of the UPS, the battery stores electrical energy and releases it when needed during power interruptions.
2. Inverter: Converts the DC power from the battery into AC power, ensuring compatibility with connected devices.
3. Rectifier/Charger: When utility power is available, the rectifier charges the battery, keeping it ready for use during outages.
4. Static switch: A static switch automatically and immediately diverts the supply of the load to be fed from the mains supply in the event of a failure within the UPS system.

In conclusion, by understanding the differences between each solution and their respective applications, you’ll be able to find the right option for your requirements; our UPS kVA Load Calculator can help identify the right uninterruptible power supply system for you.
