The previous purchase of a mountain 300W UPS uninterruptible power supply but in the blackout when the server with a fixed host and CRT monitor, asked the seller, the answer is UPS power concerns small, to change the big, but I will not calculate concerns, Ask you: how much do I need to buy a UPS?
Hills UPS conventional backup can choose TG1000, the output power is 600W, if you need to adjust the voltage can choose K1000, the output power is 600W.
Host security 500W operator, and then count the power factor, the best load percentage, you can be equipped with a 1500VA or so UPS.
UPS uninterruptible power supply selection principle:
(1) According to the placement of the load equipment, use large-capacity UPS centralized power supply program. The reason is that the failure rate of a single UPS with a large capacity is low. The price of UPS per unit of KVA is reduced with the increase of UPS capacity. When a single capacity UPS is used, it is advantageous for the user to be more economical and reasonable Use the battery.
(2) according to the user's different distribution system selection UPS models to meet the user delivery system with the ability to load requirements. (3) choose to allow the mains power supply range of large UPS models, can better adapt to the city power grid harsh power supply environment. (4) selection of UPS overload capacity and has excellent resistance to output short-circuit capability models. As long as the UPS implementation of the mains AC bypass power supply and inverter switching operation, there is always the probability of failure. Obviously, UPS anti-overload capacity is stronger, the objective UPS to do the opportunity to switch the less, followed by the UPS failure rate is lower.
(5) to have the appropriate anti-transient surge suppressor, in order to better protect the network equipment.
(6) use the UPS output center line to ground potential low model, you can get as high as possible data transfer rate, reduce the data transmission bit error rate.
(7) according to the user centralized monitoring system at different levels of requirements, with different network control functions of the intelligent UPS system.
Need to change a more than 600 USP, but the mountain should not have 600, you can buy a 1000, absolutely enough for you
