1. The need for stability
When choosing UPS products, the customer's focus must be stability. For UPS, higher power means lower calorific value. Of course, only one of the primary factors that affect the internal temperature of the UPS is also to consider the heat dissipation planning of the machine itself.
2. Echo the policy of energy conservation and emission reduction
At the beginning of 2013, the Ministry of Industry and Information Technology, together with five ministries and commissions, issued the "Teaching Opinions on the Construction and Layout of Data Centers" (Ministry of Industry and Information Technology Unicom (2013) No. 13), requiring that the PUE value of new data centers reach below 1.5, and the PUE value of the original renovated data centers should be reduced to less than 2; The loss of UPS power supply system is the primary component of data center energy consumption, accounting for about 6%-10% of data center energy consumption.
3. The customer's demand to save electricity bills
Generally speaking, every percentage point increase in the power of online UPS can save 10%-20% of the power cost, which shows that the benefits brought by UPS to enterprises are very considerable.
4. Inefficiency in customer scenarios
High efficiency is the continuous pursuit of UPS. However, many UPSs are still running at low power at the actual customer's UPS application site. - In general, the UPS practice load factor is less than 40%, and the higher the redundancy, the lower the load factor. Under low load, the power of UPS power supply will be greatly reduced. Most of the actual operating power of the existing UPS is less than 90%, resulting in a lot of power loss to customers.
The input power factor is more than 0.999, which reduces line loss and improves power utilization. Its inverter power can reach more than 98%, and then the working power of the whole machine is improved, which reduces the loss and saves electric energy. Low-load planning, adhere to the high power of 95%-96% in the common load rate segment, match the actual transaction scenarios of the data center, effectively save energy consumption, and reduce energy consumption by more than 50%.

The inverter controls the speed of the AC motor – Schneider
Most of the motors used in the industry are of this type. The rotational speed of an induction AC motor (henceforth referred to as a motor) is approximately determined by the number of poles and frequency of the motor. The number of poles of the motor is fixed by the working principle of the motor. Since the pole ...

Analysis of the causes of frequent overcurrent alarms of inverters - Schneider
(1) Caused by incorrect parameter setting.
If the acceleration time of the inverter is set too short, the change of the output frequency of the inverter far exceeds the change of the motor frequency, and when the inverter is started, it will trip due to overcurrent. Adjusting the acceleration time accordingly to different load conditions can eliminate this problem.
