When it comes to the load of UPS power supply, people first think of precision equipment such as computers. However, some products are not suitable for carrying UPS power supply. To ensure the normal and reliable operation of UPS electrical equipment, the selection of UPS power supply and the matching of load are crucial. When purchasing UPS power supply, it is necessary to understand the usage environment that the UPS power supply will face. What are some devices that UPS power cannot support to maximize their intended function?
1. Fluorescent lamp
A large surplus UPS power supply should be selected because the starting impulse current of fluorescent lamps is large and the resistive components are high.
2. Electric motor
We need to choose a high-capacity UPS power supply because it is an inductive load and has a high starting impact.
3. Air conditioning
It is generally prohibited to use UPS power supply because the air conditioning startup has a large punch and belongs to inductive loads.
4. Copiers and high-speed printers
Due to the frequent generation of surge currents during its operation, it cannot be loaded.
5. Electric furnace wire (pure resistance load)
We need to choose a high-capacity UPS power supply as it belongs to resistive loads.
6. Laser printer
Large surplus UPS power supply should be selected as it often generates surge currents during its operation.
