Question:

UPS power supply room purchase program

Equipment room equipment as follows IBM X3650 M2 server one Rated voltage 100-127 / 200-240v Rated current of 7.8 / 3.8A IBM X3650 server one Rated voltage 100-127 / 200-240V Rated current 10A / 5A Ordinary switch a model parameter is unknown DVR A model parameter is unknown Mainly to ensure that the server can be power supply, the external power supply can be guaranteed to disconnect more than half a day can hope that the list of models, and the number of battery I am not very understanding of this, I hope to be able to explain in detail.

Answer:

The choice of UPS power supply room is based on the equipment required by the engine room, metaphor is equipped with monitoring, servers, switches and the like are capacitive load, buy UPS power supply when you choose a high frequency machine on it. If it is a printing press, automation equipment. Automatic access control system and so on belong to the inductive load, need to match the power frequency UPS power supply. Select the appropriate UPS according to the size of the load when selecting UPS. The load is generally 60-70% of the UPS capacity is appropriate. Backup time is based on the needs of customers with configuration!
Buy UPS to be divided into several steps: 1. According to the importance of the type of load to determine the structure: the landlord for the server equipment, the need for on-line UPS, if the home computer only need to buy cheap backup UPS 2. According to the load power to determine the power of the UPS section: the landlord of the two server power of 220V * 3.8A +220 V * 5A = 1936W switch + hard disk video recorder power is 200W-300W, so your total load power of about 2200W 3. consider the need for expansion, if you are not ready to add the server in the near future, buy a UPS can only load these loads, if the follow-up is also prepared to increase the service to 4 or more, then try to buy a little more power ups 4. You need to buy the UPS power of 2200W / 0.6 = about 3600W (0.6KW for the UPS's safety carrier load rate), and then remove a UPS input power factor 3600W / 0.8 = about 4500VA, rounded to 5KVA The proposed landlord to buy 5KVA online UPS, according to your application scenarios, the preparation of electricity 4 hours enough, the battery selection 12V20AH * 20 string UPS together with the battery price is expected to buy RMB8000 on the market Kehua Keshi Da Tiandi other brands such as high cost of the UPS Note: This configuration is more upscale, because although your two IBM servers marked with the rated power of 1936W, but according to my experience when the actual work will be less than 1000W (also 800W), plus your switch And hard disk recorders, generally 1200W load, buy a 3000VA / 2100W UPS can also be used, but if the server is unusually large when the power consumption may be due to the machine output power is not enough will be affected, so if the landlord is not bad money, Try to buy 5KVA, after you bring 2-4 IBM server or add 10 office computers together do not affect.
