| Operation mode of Santak power UPS |
| Time：2018-10-04 Source： Views：3223 |
Shante UPS power supply is a common uninterrupted emergency power supply system, and its working mode is different under normal and abnormal power supply. This paper mainly introduces four working modes of Shante UPS: normal operation, battery operation, bypass operation and bypass maintenance.
1. Normal operation mode
The power supply principle of Shenzhen Shante UPS power supply system is that when the city power is normal, the machine will convert the AC power to DC power, and then charge the battery for use in case of power interruption; it should be emphasized that the uninterrupted power supply system will not work only when the power is cut off, such as when the voltage is too low or too high, instantaneous burst, and so on, enough. When the power quality of equipment is affected, UPS system is in working state, which provides stable and clean power environment for load equipment.
2. Bypass operation mode
When on-line Shante UPS emergency power supply overload, bypass command (manual or automatic), inverter overheating or machine failure, the UPS power supply generally converts the inverter output to bypass output, that is, direct power supply from the city. Because the output frequency phase of UPS should be the same as that of power supply, the phase-locked synchronization technology is adopted to ensure the synchronization of power supply output and power supply. Bypass switch bi-directional SCR parallel operation mode, solve the bypass switching time problem, truly achieve zero time switching, control circuit is complex, generally used in high-power UPS power supply. If UPS is overloaded, the load must be reduced manually, otherwise the bypass short circuiting device will automatically cut off the output.
3. Battery working mode
In case of abnormal power supply, Shenzhen Shante UPS converts the DC power stored in the battery into AC power. At this time, the input of the inverter is supplied by the battery pack. The inverter continuously provides power, and the supply load continues to use to achieve the function of continuous power supply. The power source of UPS power supply system is battery, and the capacity of battery is limited, so the UPS system will not continue to supply power like city power, so no matter how large the capacity of UPS power supply system, in its full load state, its power supply time must be limited, to extend the discharge time, you must buy more batteries. Capacity and battery pack to meet UPS power supply.
4, bypass maintenance mode
When the UPS power supply is repaired, the normal power supply of the load equipment is guaranteed by setting the bypass manually. When the maintenance operation is completed, the UPS power supply of Shante is restarted and the UPS power supply is turned into normal operation.
