How do I determine the right uninterruptible power supply size?
To size your needs: Total watts of your equipment x their total amperage and add 15% of that total to get your total requirement. The difference in UPS capacity compared to its load can increase runtime if significant enough. This article explains how to determine the right uninterruptible power supply size to fit your needs.
What is an uninterruptible power supply (UPS)?
An uninterruptible power supply (UPS), offers guaranteed power protection for connected electronics. When power is interrupted, or fluctuates outside safe levels, a UPS will instantly provide clean battery backup power and surge protection for plugged-in, sensitive equipment.
How much power does an ups need?
When sizing a UPS for your specific requirements, the power factor matters most. Generally, your UPS should have an Output Watt Capacity 20-25% higher than the total power drawn by any attached equipment. How much runtime do you need to support your attached equipment? That depends on what you intend to backup with your UPS.
Can I have multiple ups installed?
You can have multiple UPS installed, depending on your requirements. It may be worth looking into having a backup generator installed that will provide enough power, and then looking for a UPS system that can provide enough juice until you can power up the backup generator accordingly.
Do I need a 5 minute ups if my PC shuts down?
Since you just want to power down gracefully, then that should be achievable with a 5 minute UPS. Also, if the PC shuts down automatically, then there is no need to have the monitors on the UPS - you just need your PC. Shutting down should not be power consuming. Hi iosn,
Do I need a 5 minute ups if I have a power outage?
Remember that if you get a power outage then all the peripheral equipment is out - no modem router, etc. Since you just want to power down gracefully, then that should be achievable with a 5 minute UPS. Also, if the PC shuts down automatically, then there is no need to have the monitors on the UPS - you just need your PC.
