The Santak UPS power supply system is mainly composed of the following parts:
UPS host
Required functional components (such as BCBBOX, etc.)
storage battery
Supporting battery cabinets/racks, battery switches, etc
Functional options (such as lightning protection, monitoring, harmonic control, upper and lower output lines, etc.) Input characteristics:
1. A wide input voltage range can reduce the chance of battery discharge and extend battery life.
2. Low input power factor, high input reactive power, harmonic current pollution of the power grid, affecting other equipment
3. The allowable range of main power frequency.
4. Input current harmonic components. (PFC, 6/12 pulse transformer) output characteristics:
（1）Static stability. 1% for large and 2% for small and medium-sized.
（2） Output transient characteristics. Large 5%, medium and small 8%.
(e.g. overload 125% 5MIN; 150%10S.
（3）Output overload capability.
（4）Output power factor. (0.8、0.9、1)
（5）Output voltage harmonic distortion. Typically within 3%.
Santak UPS Power Supply – Santak UPS Power Supply Related Configuration and Calculation
Calculation required:
UPS host capacity calculation and selection
Capacity Calculation and Selection of UPS Backup Batteries
UPS Capacity Calculation and Selection
Firstly, obtain the total power consumption of the load and unify the unit to KVA
For example, the load of a typical personal computer is about 200VA, the load of a small server is about 1500VA, and the load of a large or medium-sized server is about 3000VA. The conversion relationship between current I (A ampere) and power consumption W (watt) and VA
VA=1220
VA=W/0.8 (usually considered as 0.7 below 20KVA and 0.8 above 20KVA during calculation)
Considering that UPS operates in the optimal range of 60-80%, it is generally recommended to divide the above result by 0.8 and amplify it again before selecting the closest power product in the product manual
Using constant power mode calculation method
W/cell=PL/(Nx6xη)
Introduction to UPS Power Supply Solution
Centralized power supply method
Advantages: It can achieve equipotential control of network device resources and reduce transmission error rates.
Disadvantages: Large initial investment and significant impact of single machine failures.
Distributed power supply mode:
Advantages: Flexible scheme layout and minimal impact of faults.
Disadvantage: If the entire device cannot maintain the same ground wire, it is easy to cause.
