FAQ

I now have to design a set of UPS capacity of about 600 cameras, 40 LCD monitors (19 inches), 14 hard disk recorders, a matrix. There are 50 pairs of optical machines. Who knows this, the trouble told me about how much need to be equipped with the UPS.

The key of this camera is too wide, a few W to several hundred watts have. 40 LCD, if it is LED, also 2KW. If it is old, about 4KW DVR is also a 200-300W * 14 = 4.3KW Optical do not have to forget, too small. Matrix ... no specific parameters. If it is a terminal camera, each about 3-5W, probably a total of 20-30KVA is enough. ? If it is a film camera (estimated not, or else 600 too much): The key is that even 600 cameras every 20W, have 12KW. 20KVA if you need insurance. If it is 200W, you need 200KVA. And the camera is not also need to have a matching mobile shelves, if there is a motor, it is estimated how to use hundreds of KVA only safe. If there are still lights: a camera can take 2.6KW lights, it is estimated that the astronomical figures.

Half load is not that half of the load, full load is full load? I am a novice, I hope the old chefs do not joke.

Simple understanding, if the UPS rated output is 300W, full load refers to the UPS rated 300W, connected to the UPS above the load input power is 300W, half load is connected to your UPS above the load is 150W

Brother for the first time to play ups would like to ask about this connection is wrong. I am connected to the uninterrupted power supply on the spark, what is the problem ah?

At this time the connection method is short-circuited, so take a fire.

What does UPS mean?

Uninterruptible power supply, is a small box, one attached to the AC, a computer and other computers need to continue to do when the power to save the work of electronic products, which charge the power, the ordinary UPS can also be used when the power 2-20 minutes or so.

UPS power supply behind the serial how to use?

You can insert the card reader, before and after the same.

Will UPS burn in those cases? Is the mains voltage exceeding the input voltage range? Or because the load percentage is too large?

Large brand of UPS beyond the input voltage range will not burn, with a large percentage of load will not burn. Because UPS has a self-protection function. Voltage, load out of range UPS does not work. 90-270 access 380UPS does not work. Will not burn. Unless you sell fake. General burn is the aging of components, or internal dust, static and other UPS internal reasons. Cottage UPS I do not know. 380 input with 220 electricity will not burn, the voltage is too low when the battery-powered UPS work properly.

What is the difference between UPS and RPS power supply?

RPS power supply (Redundant Power System) is used as an external DC power supply for some switches RPS can be used as a redundant backup power supply for a switch or router: L If the RPS and the power receiving equipment adopt the same AC power supply system, the RPS can continue to supply the DC power supply to the faulty equipment when the internal power supply of the power equipment is abnormal. The equipment will continue to operate normally. L If the RPS and power receiving equipment use different AC power supply system, you can also provide DC power supply to ensure the continuous operation of the equipment when the external AC power supply fails.

What is the uninterruptible power supply

UPS (Uninterruptible Power System), that is, uninterruptible power supply, is the battery (mostly lead-acid maintenance-free battery) connected with the host, through the host inverter and other modules to convert DC power into the main system equipment The Mainly for a single computer, computer network systems or other power electronic equipment to provide a stable, uninterrupted power supply.
