Q:What is the relationship between this tile and kva?

I recommend the use of frequency machines, because the frequency machine with a strong load capacity, but will be more expensive. 10KVA is apparent power, W is active power.

Q:Need to replace the backup battery

Ok can support a desktop + printer + monitor for 6 hours? To answer Can support, MT1000S and C1KS need external battery. According to your request MT1000S external 4 100AH battery, C1KS external 6 100AH battery on it

Q:The room with the ups power supply why some cold start, and some to hot start, why the hot start must be connected to the mains. What is the difference between the internal principle of the product is it, thank you

UPS normal start and cold start; normal start is a mains, there are batteries in the case of direct start UPS; cold start is no electricity, there are batteries, the battery directly start. A lot of Epson UPS is not one machine, there is no battery on the host, are external battery. There is no need to start the cold UPS power supply. If the battery fails, you can only replace the battery.

Q:When the electricity is used to put the battery in the battery with the electricity out of the USP automatically turned off by the open up with a one will put the electricity out of a power outage UPS can only work two minutes ago almost 10 minutes I used UPS with a Computer host and a liquid crystal display

You put the battery with a bad! do you know? UPS automatic shut down is to protect the battery, do not let the battery over discharge! If you use this, the battery is damaged due to excessive discharge! There is a way do not know can not, you can try to remove the battery out, with an external charger, a separate charge to each battery, filled with about 13.6 ~ 14V it, you find a load to it discharge, probably put 10 ~ 10.5V! Put it in after charging it, in the discharge, repeated several times! If you are lucky, the battery can be restored about 80%! If luck is not good! Then you honestly change the battery!

Q:Do not understand the ups on the 3 into the 3 out of this parameter in the end what advantage!

As for the advantage is nothing, but 3 into 3 out of the relatively stable point, this is mainly to see your own needs, you want UPS to provide you with what kind of power (380/220).

Q:What is the role of UPS uninterruptible power supply?

As the development of information technology, the network has become an indispensable part of people's lives and work, constitute the network of digital room power supply reliability has become the key, and the reliable power supply room is the most important,

Q:Power supply and ups power which is good?

1, power supply: it is designed for voltage instability, mainly as a back-end equipment to protect the use of equipment protection function is more perfect. General large UPS must also be equipped with a regulated bypass system. The scope of the power supply is very broad, almost need to use the electricity can be used (of course, the premise is the voltage instability). General home with a computer, with a TV, etc., choose high-precision automatic power supply can be, and is the market called SVC AC power supply, the price is real; if it is industrial, then of course, is the high-power AC voltage regulator Power, simple and practical. For the UPS power supply and power supply above are made a good introduction and description, hope that these can understand you for the regulator and UPS can have a very good help, so you in the future life can be very easy to distinguish them , And they can be used better.

Q:When the UPS load belt with more cases, in the absence of electricity when his duration will be short But if a UPS in the case of electricity, there will be no load too much, and over load, can not work properly?

The proposed load is less than 80% of the UPS capacity, because some load will have a high starting current, the load is too large will lead to UPS downtime risk, after the UPS problem can directly consult the Shanghai Wu Mai Electronic Technology

Q:Ups uninterruptible power supply back - up and on - line difference is what does anyone know?

Backup UPS is also known as non-online UPS ??Backup UPS: usually in the battery charge state, in the event of an emergency switch to the working state of the inverter, the battery provided by the DC into a stable AC output, so the backup UPS is also known as off-line UPS. Backup UPS power supply advantages are: high efficiency, low noise, the price is relatively cheap, mainly applicable to major fluctuations in electricity, the power supply quality requirements are not high occasions, more suitable for home use. However, this UPS has a switching time problem and is therefore not suitable for use where critical power supplies can not be interrupted. But in fact this switch is very short, usually between 2 to 10 milliseconds, and the computer's own switching power supply in the power failure should be able to maintain about 10 milliseconds, so the personal computer system is generally not because of this switching time problem. Backup UPS can only continue to power a few minutes to tens of minutes, mainly to let you have time to back up data, and as soon as possible the end of the work, the price is low. For computer applications that are not too critical, such as personal home users, they can be equipped with a low-power backup UPS.

Q:Output so 175 volts. Electricity is normal

Then you might as well do not use the UPS, the output 175, the load can work properly? The electricity is also stable than it is
