What are the main uses of Shante UPS power supply and which industries use it?Shante UPS power supply is widely used in mine, aerospace, industry, communication, national defense, hospital, computer business terminal, network server, network equipment, data storage equipment, UPS uninterrupted power supply, emergency lighting system, railway, shipping, transportation, power plant, substation, nuclear power station, fire safety alarm system, wireless communication system, program-controlled switch, mobile communication, etc. Solar energy storage conversion equipment, control equipment and emergency protection system, personal computer and other fields.
UPS power supply is a system equipment that connects the storage battery (mostly lead-acid maintenance-free battery) with the host computer, and converts DC current into market electricity through module circuits such as host inverter. Mainly used to provide a stable and uninterrupted power supply for a single computer, computer network system or other power electronic devices such as solenoid valves, pressure transmitters, etc. When the city power input is normal, UPS will supply the city power to the load after stabilizing the voltage. At this time, UPS is an AC city power regulator, and it also charges the batteries in the machine. When the city power interrupts (accident power outage), UPS will immediately supply the DC power of the batteries to the load through zero-switching inversion method to continue to supply 220V AC, so that the load can maintain normal work and protect the soft and soft loads. Hardware is not damaged. UPS devices usually provide protection against high or low voltage.
UPS battery configuration scheme and UPS uninterruptible power supply selection method:
Battery power supply time is mainly affected by load size, battery capacity, ambient temperature, battery discharge cut-off voltage and other factors. According to the delay ability, the capacity of the required battery is determined, expressed by the AH value of ampere time, and calculated by the time hours of discharging when the ampere number of current is given.
General UPS configuration is calculated by the following formula:
UPS power supply power (VA)*delay time (hours)UPS power supply start DC = required battery ampere hours (AH)
Taking Shante C3KS as an example, we calculate the following: Note: The starting DC of Shante C3KS is 96V.
3000 volt-ampere x 4 hours_96V = 125AH
The result is that 125 AH batteries are needed to supply power for 4 hours, but ordinary batteries generally do not have a group of 8 batteries with a capacity of 125 AH (because the starting DC of C3KS is 96V - (the standard DC voltage of UPS at the time of factory). Generally, most batteries are 12V DC, 96V (the starting DC voltage of UPS) 12V (the DC voltage of battery) = 8, so eight batteries are used as a group).
We can choose a set of 100AH batteries to configure it; the delay time is 100AH (battery capacity)*96V (UPS start DC)3000V (UPS power)=3.2 hours.
Two batteries (16 batteries) of 65AH can also be configured in parallel. The delay time is 65AH*2*96V_3000VA=4.16 hours.
