Case Profile: SMT factory UPS power solutions, providing a good stable and reliable power supply for the electronics factory green cleaning of production equipment to ensure the safe operation of the production line.
The UPS system dedicated UPS power supply construction SMT production line is mainly for power plant equipment placement machine production within a few seconds due to production line outage also make great loss suffered by the user, so the need to provide highly reliable power supply power scheme.
Through communication with the plant-related departments, we learned: several production lines Mounter unified configuration and a powerful UPS power, back-up time of 15 to 30 minutes. Advantages: easy unified management, relatively low cost, you can use a larger battery capacity, longer life batteries.
UPS configuration design principles - fit enough to avoid waste and unnecessary cost of upgrading the capacity of .UPS selection mainly by the size of the load, the characteristics of the load and the size of the reserved capacity determined. Factors are generally considered: First, UPS must be greater than the total capacity of the load carried; secondly, the different characteristics of the UPS load capacity requirements are also different resistance characteristics such as the load approaches, the input power factor is greater than the UPS output power factor (. typically 0.7-0.8), press the UPS output power factor calculation; the input power factor as the load is less than the UPS output power factor, the input power factor press load calculated. Third: To ensure long-term stable operation of UPS load capacity is generally not more than 80% UPS capacity, and the newly installed UPS generally also set aside a certain load margin expansion. Fourth, in order to improve reliability, can be N + 1 parallel redundant mode, the load highly reliable supply of electricity. N devices that provide power supply to the load, a piece of equipment to ensure the redundancy, when the system has any device failure, power supply load can also be guaranteed.
