What is a UPS (uninterruptible power supply) calculator?
A UPS (Uninterruptible Power Supply) Calculator is a vital tool designed to help users determine the appropriate UPS size required to support their electronic devices during a power outage. This calculator assists in ensuring that all connected devices can continue operating smoothly without interruption when the main power source fails.
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.
What is a watt rating on a ups?
However, the Watts rating determines the UPS’s “real power.” In a circuit running on direct current (DC) energy, watts equal volts times amps, where 1 kW = 1 kVA. When the uninterruptible power supply uses AC energy, which is what most buildings run on, it reduces the available wattage, creating what’s known as a power factor.
How does an uninterruptible power supply work?
All uninterruptible power supplies offer different runtimes based on the system’s rating, total load, and battery capacity. UPS ratings are measured in volts amps (VA), kilowatts (kW), or kilo-volt-amperes (kVA), indicating the maximum energy the uninterruptible power supply can deliver. However, the Watts rating determines the UPS’s “real power.”
Can I use ups if my power needs more than wattage?
Yes, as long as the total power requirement of all devices does not exceed the UPS capacity. Always calculate the total load and choose a UPS that can handle the combined wattage. The UPS Calculator assists users in selecting a UPS system that matches their power backup needs by calculating the required capacity.
What is ups capacity?
Capacity is how much power a UPS system can provide (measured in Watts). The higher the capacity, the more electronic equipment, and devices it can support. A good rule of thumb is not to exceed the rated capacity of the UPS by more than 80% of the UPS. Be sure to allow for inrush currents of fans, capacitors and motors.
