im confused on what to buy for our recently purchased PC set, unsa man mas preferable an AVR or UPS, seems i cant buy both ky were on tight budget,
for sure AVR is not capable of back up power, ang UPS cable ba mo regulate power?

Buy UPS atleast 500W. Kanang daghan ug features like u can backup, surge protection etc...
Ive been using UPS for 3-4 yrs already and its very convenient.
ya try to use a UPS rather than AVR becuase thier are ups that are voltage regulator already....... if you like YM me for more inquiries.... apc_three.![]()
i go for ups , stable man kaha inyo kuryente diha
stable rna bro.
wla nay problema.
maayo na ang ups kay lisod kung in the middle of the game kay mag brownout.
hehehe
IMO... AVR mas importante kesa UPS. lalo na pag power serge ang kalaban. Advantage talga ang AVR. This will save your hardware.
Uninterruptible Power Supply Technologies Explained
Offline, Online and Line-interactive
What's the difference, and which technology is right for you?
There a three different types of UPS all suitable for different tasks, and supporting different types of load. Here are explanations of the different technologies, along with their advantages and disadvantages. Hopefully it will help you decide which type of UPS is suitable for you:
Offline-Standby Technology
During normal operation, the power flows straight through the unit and hence only RFI filtering is usually provided. When the input voltage fails or fluctuates outside of a pre-set tolerance window, the UPS detects this and a relay will close, allowing the UPS to start feeding battery power via the inverter. The inverter is then switched on and either a square, step or sinewave form output is supplied. Upon the return of mains power, the output is switched back onto mains and the inverter is turned off. Typically there will be a break of between 4-10 ms during the transfer to and from the battery mode.
Advantages: Low cost
Silent operation (when in standby)
Efficient
Disadvantages: Minimal power protection – only protects against a small percentage of problems
Poor output voltage regulation – fluctuations such as sags and surges will be passed straight to the load
Break transfer to battery mode
No failsafe – UPS will drop the load if there is a high start-up current, overload or inverter failure.
Line-Interactive Technology
A line-interactive UPS operates in a very similar fashion to an offline UPS, except with the advantage of better filtering and output voltage boost/reduce features. Whilst not eliminating mains-borne interference, line-interactive technologies reduce the impact of spikes, surges and sags by ‘clipping’ the peaks and valleys, boosting power or switching to battery back-up. As with offline UPS, when the input voltage fails or fluctuates outside of a pre-set tolerance window, the UPS detects this and a relay will close allowing the UPS to start feeding battery power via the inverter. The inverter, in a good line-interactive UPS, will supply a sinewave output. Upon the return of mains power, the output is switched back onto mains and the inverter is turned off. As with offline UPS, typically there will be a break on the transfer to and from battery mode, though usually this will be shorter than with an offline UPS.
Some manufacturers will try to pass their line-interactive UPS off as online models by calling them ‘digital online’, ‘inline’ or ‘online interactive’ – make sure you know what technology the UPS you are buying actually uses.
Advantages: Lower cost than online
Gives better protection than offline
Silent operation when in standby
Efficient
Disadvantages: Fluctuations, such as spikes, can still be passed straight to the load
Break on transfer to battery mode.
No failsafe – UPS will drop the load if there is a high start-up current, overload or inverter failure.
Online Double Conversion Technology
An uninterruptible power supply using true online double conversion technology provides the highest level of power protection available. The UPS converts the 230V input AC mains supply to DC power which is then used to charge the battery. The DC current flow is then fed through an inverter stage which reconstructs the 230V AC mains output. Because the AC output is completely regenerated, it will be completely free from any mains-borne interference such as spikes and voltage variations. The output voltage and frequency is controlled precisely, thus ensuring a clean and stable sinewave power output. Online UPS are able to withstand large fluctuations on the input voltage before transferring to battery power (typically 276V-184V) thus eliminating unnecessary battery discharges. Upon mains failure, transfer to battery power is seamless – no break. Online UPS also have various failsafe and self-diagnostic features that will instantly transfer the load onto mains power if there is a failure within the UPS hardware, or if the UPS is overloaded.
Advantages: Continuous & total power conditioning
Failsafe/overload protection with static bypass facility
No break on mains failure
Wide input voltage tolerance
Disadvantages: Because of the technology used, online usually costs more
hope maka decide na ka and to give info sa wala pa info about ups
depend on the brand of the ups naa sad ups with voltage regulation so avp and ups in one na.....
The problem with UPS is, if you have just a low budget, the UPS you get for that is crap. Battery wont last long.
matsalams sa mga reply, at least i have a starting point on what to purchase
APC or GIANT UPS reliable brand in the market. Im using GIANT for 3-4 yrs and its very reliable, all you have to do to make the battery last long, turn the UPS off when not in use. Kay for me I need not to backup man jud coz I have 500w actually then it would only last for 30-45mins when fully charged, pero for me I need not to do that as long as it protects me from brownouts, surge etc..ok na.
Dugay na jud ni akoa pero same as new ever got no problem.
