An uninterruptible power supply (UPS) provides guaranteed power protection for connected electronics. When power is interrupted or fluctuates out of safe levels, a UPS will instantly provide noiseless power from the emergency battery and protection against overvoltage to sensitive equipment connected to it.
Why You Need A UPS At HOME
The electronic devices that you depend on daily for communication, security, and entertainment risk being damaged or failing due to voltage fluctuations, power outage, or other power disturbances. A UPS battery provides emergency power and protection for your electronics such as:
- Wireless network equipment (routers, modems)
- Computers
- Televisions
- Security systems
- Game consoles
- Mobile devices
Why You Need A UPS AT YOUR Company
Downtime caused by prolonged service cuts is can be frustrating for anyone but can be financially devastating for companies or organizations. Billions of dollars are lost every year due to downtime caused by power disturbances that could have been avoided with a UPS
Small to medium-sized companies are perhaps the most subject to financial risk due to their limited ability to generate revenue during downtime.
What UPS Size Do You Need?
Electronic systems have both a maximum watts value and a maximum VA (volt-ampere) value. Neither one nor the other value can be exceeded by the connected equipment. The watts measure the active power consumed by the equipment, while the volts-amperes are the product of the voltage applied to the equipment times the current consumed by the equipment.
The Power Factor
In the case of computers and UPS units, the watts and VA values can differ significantly, although the VA value is always equal to or greater than the watts value. When dimensioning a UPS for your specific needs, the power factor has the most weight. In general terms, your UPS should have an output capacity in watts 20% to 25% higher than the total power consumed by any connected equipment.
How Long Do You Need To Keep Your Equipment Up And Running?
This depends on what you want to protect and power with your UPS. Run time refers to the amount of time that a UPS will be able to power connected equipment in the event of a power failure. The more equipment you have connected to your UPS, the less uptime you have. Therefore, it is important to ensure that your UPS is only providing emergency power for your most critical equipment.
What Power Conditions Will A UPS Emergency Battery Protect Against?
Many supply problems stem from the commercial electrical network, which, with its thousands of miles of transmission lines, can be damaged by weather variations, traffic accidents, and equipment failures.
Some Basic Features to Know When Choosing a UPS System
- The batteries should be replaceable – it allows you to perform battery replacements and updates.
- Overvoltage protected outputs – Protects your secondary devices against prolonged or short over-voltages without minimizing the battery power used to allow primary electronic devices to function during power cuts.
- Connection failure indicator – In case of a problem with connections, a LED indicator informs the user.
