·The Equipment Suitable for UPS
Uninterruptible power supplies, commonly used to protect critical equipment, such as: computer equipment, precision instruments, medical instruments. Because UPS R & D design to computer-based, not all loads are applied, in particular the inductive load, such as electric fans, air conditioners and other appliances do not apply. Because there will be inductive load back-EMF generation, for off-line UPS will cause harm. In addition, like copiers, laser printers, etc.-activated currents in the larger equipment shall not be applicable to UPS, because of its instantaneous starting current big. If the UPS capacity is insufficient, could easily lead to transient overload. Once coincides with electricity outages, UPS output is interrupted. UPS usually use a long period of overloading, it will shorten the life span of electronic components and UPS.
