  • Patent number: 11243591
    Abstract: An uninterruptible power system and an operation method thereof are provided. The uninterruptible power system has a plurality of function blocks which form a topology structure of the uninterruptible power system. The uninterruptible power system comprises a sensing circuit and a control circuit. The sensing circuit is configured to sense the function blocks and to generate a sensing data accordingly. The control circuit is configured to determine, according to the sensing data, whether an event occurs in any of the function blocks. When the determination is yes, the control circuit generates an event code corresponding to the event and outputs a control command accordingly. The control command is used to control a display interface to display the event code, and is used to control the display interface to send a prompt message through a function block graphic symbol corresponding to the event code in the displayed topology structure.

  • Patent number: 9929592
    Abstract: A UPS sensitivity of power status parameter adjustment setting method used in UPS system for allowing sensitivity setting of power status parameter manually by user or according to system default value. Microcontroller can automatically switch sensitivity to HIGH to enhance power protection if power status of input power supply is judged in the range set according to option of energy-saving, electrical safety or set time in priority after completing counting time. If power generator of relatively lower power quality level is used for input power supply, microcontroller can automatically switch sensitivity to LOW subject to option of energy-saving in priority and employ a low-sensitivity detection of power judgment, maintaining USP system in normal mode without being changed to battery mode, preventing system shutdown due to complete discharge of stored energy systems, and UPS system can operate normally, and power supply of stored energy systems can be prolonged and well-protected.

  • Patent number: 9929593
    Abstract: A multi-output power management method used in a UPS system for enabling a microcontroller to determine whether to execute an automatic setting or manual setting. In automatic setting, the microcontroller conducts the parameter setting of a multi-output selector output mode, and switches a multi-output selector to a bypass or DC to AC inverter output mode after confirming that the power status parameter is in a predetermined multi-output selector parameter setting range. In manual setting, the multi-output selector can be manually switched to the bypass or DC to AC inverter output mode. Thus, multiple switching units of the multi-output selector of the UPS system can be respectively selectively switched to the bypass or DC to AC inverter output mode to provide different AC outputs to a respective load under the priority of energy saving or electrical safety, enhancing the electrical efficiency of UPS system and achieving the effect of energy saving.

  • Patent number: 8952277
    Abstract: A power-switching device with interlock mechanism has a housing with a rotary knob, a slider slidably moved into a rotation range of the rotary knob, and an activation switch mounted on a sliding path of the slider. The activation switch has a control button located on an overlapped portion of the sliding path of the slider and the rotation range of the rotary knob. When the slider approaches the rotary knob, the activation switch is activated and the rotary knob is unable to rotate for being blocked. When the slider departs from the rotary knob, the activation switch is deactivated and the rotary switch is rotatable. Accordingly, when manually bypassing a UPS by turning the rotary knob, users will not forget to deactivate the activation switch, thereby avoiding damaging the UPS.
