What Is Online Double-Conversion UPS Technology?

/

Introduction Online double-conversion is a UPS architecture designed for continuous power conditioning and protection. How It Works The incoming AC power is converted to DC and then converted back to AC before being delivered to the connected load. This creates a controlled output supply for connected equipment. Why It Matters Online double-conversion UPS systems can be useful for applications where: Where Are They Used? Common application areas include: Final takeaway The UPS architecture should match the importance and sensitivity of the connected equipment.

How to Choose the Right UPS Capacity for Your Equipment

/

Introduction UPS capacity is commonly expressed in VA and watts. Choosing a UPS solely because its VA rating appears sufficient can be a mistake. The connected load and required operating margin also matter. Start With Your Load Identify the equipment that needs protection and determine its expected power consumption. Consider VA and Watts VA represents apparent power while watts represent real power consumption. The relationship between the two is affected by power factor. Allow Appropriate Capacity Avoid selecting a UPS that operates permanently at its maximum capacity. A suitable operating margin can provide additional flexibility for changing loads. Consider Runtime If backup runtime matters, battery capacity and external battery options should also be evaluated. Final takeaway Tell Power Icon your equipment and load requirements rather than selecting a model based solely on its headline capacity.

Online UPS vs. Standby UPS: What’s the Difference?

/

Introduction Not every UPS uses the same power-protection architecture. Two commonly discussed approaches are standby UPS systems and online UPS systems. Understanding the difference can help when evaluating equipment for critical applications. Standby UPS A standby UPS normally supplies incoming utility power to connected equipment and switches to battery power when the input supply fails or moves outside acceptable limits. Online UPS An online double-conversion UPS continuously processes incoming electrical power before delivering output power to the connected equipment. This architecture is commonly used where power quality and continuity are important. Why Choose Online? Online UPS systems can be appropriate for: Final takeaway UPS selection should be based on the actual application rather than simply choosing the cheapest available backup system.

What Is a UPS and Why Does Your Equipment Need One?

/

Introduction A UPS, or Uninterruptible Power Supply, is designed to provide protected electrical power to connected equipment during power disturbances and outages. For businesses operating computers, network infrastructure, medical equipment, industrial electronics or other sensitive loads, a UPS can form an important part of an overall power-protection strategy. What Does a UPS Do? A UPS can help protect connected equipment from: Online UPS systems take power protection a step further by continuously converting incoming power before supplying the connected load. Why Is This Important? An unexpected power interruption can cause equipment shutdown, interrupted operations, and potential data or equipment problems. For critical environments, maintaining protected power can be an important operational consideration. Final takeaway The right UPS depends on the equipment, electrical load, required runtime, and operating environment.
