Tips on buying a UPS
So you’re thinking about investing in a Uninterruptible Power Supply or UPS. Here are some things to consider before purchasing. Let’s discuss the key difference and specific applications that your need to know when it comes to meeting your specific needs.
What is UPS?
UPS stands for Uninterruptible Power Supply. In the case of an unexpected power failure, whether it affects your home or business, when it comes to protecting crucial electrical equipment, a UPS is a must.
How does UPS work?
A UPS device works by converting AC (alternating current) to DC (direct current). The current is then stored as usable energy that can safely power electrical components in an emergency situation. A common example would be power outages caused by natural disasters. The UPS provides emergency power to your electrical devices when the primary power fails. A UPS can also provide protection from power surges by intercepting a surge, keeping your electrical devices safe.
What are the Different UPS types?
Depending on your specific needs, here are somethings you should consider when buying a UPS:
There are three types of UPS that provide specific levels of power protection: standby, line interactive, and double conversion (online).
Standby:
Standby will cover your most basic needs. In an unexpected loss of power, a standby UPS will switch from DC battery power to AC power to keep your connected electronics running. These models are best used for consumer electronics such as computers, laptops, and other common electronic equipment.
Line interactive:
This allows your UPS to manage and correct minor power fluctuations (under-voltage or over-voltage) This is achieved by using an autotransformer that regulates low voltages and over voltages without having to switch to the backup battery. This type of UPS will keep your electronics protected in an unexpected emergency.
Double-conversion (Online) UPS:
This type of UPS provides consistent, clean, and near perfect power regardless of the condition of incoming power. Incoming AC power is converted to DC power, and then back to AC. UPS systems with this technology operate on isolated DC power 100 percent of the time. There is a zero-transfer time because there is never a need to switch to DC power. Double-conversion UPS systems are specifically designed for protection of mission-critical IT equipment, data center installations, high-end servers, large telecom installations, storage applications, and advanced network equipment where it is crucial to protect from damage caused by such situations as power blackout, voltage sag, voltage surge, over voltage, voltage spike, frequency noise, frequency variation, or harmonic distortion.
Not all UPS are Created Equal
When it comes to UPS it is important to know your specific needs and be familiar with key differences for certain applications. There are two fundamental differences you should know about when it comes to power output and that is the two types of functions: simulated sine wave, and sine wave.
Simulated sine wave output: For basic needs most UPS function as a simulated sine wave output waveform. It uses pulse wave modulation to generate a stepped, approximated sine wave. Simply put, simulated sine wave output is a cost-effective way to protect your electronic equipment and will cover your basic needs. This form of wave function is found in most standby and line interactive UPS systems. It’s important to note that Simulated sine wave may damage appliances that use AC motors like refrigerators, microwaves, compressors, and sensitive medical equipment.
Sine wave output: This is the highest quality waveform output. It is smooth, repetitive oscillation of AC power. In other words, it produces similar power output of your standard electrical outlet. This is a prime consideration when it comes to critical equipment that is particularly sensitive to input power such as medical equipment. Sine wave will protect even your most sensitive electronics.
Other important factors to know when purchasing a UPS
Be very aware of your specific needs. Here are somethings to consider when looking for a UPS right for you:
Length of plug:
First thing that should not be overlooked is the length of the plug. Make sure your device has a plug long enough to suit you’re set up.
UPS wattage output:
Next is the capacity of the UPS battery. Look for UPS that has an output of at least 800 watts for best performance capabilities.
Sine wave:
If you’re intending to run appliances such as refrigerators, microwaves, power tools, or crucial medical equipment, it is recommended that your UPS uses a sine wave output to ensure proper function and safety.
When it comes to UPS systems, what brand is best?
It is wise to do your homework. There are many brands that are well suited and reputable. Just be certain that the brand’s product meets your specific needs, from your basic cost-effective home needs to mission-critical systems that are crucial to keep your sensitive equipment safe.
If you are in southeast Asia, Thailand has a very affordable and high-quality product. If you’re interested, look up Syndome uninterruptible power supply systems.
In conclusion
With todays modern world so reliant on electronic equipment, whether it’s for your home needs, especially if you work at home as a virtual assistant, or crucial to your business operation. A UPS will provide you with safety and peace in mind, when it comes to the unexpected.
