An on-line uninterruptible power system and an operation method thereof are provided. The on-line uninterruptible power system comprises a first switch unit, a second switch unit, a charging circuit, a DC-AC conversion circuit, a power factor correction circuit and a control circuit. When the on-line uninterruptible power system is in a line mode, the control circuit controls the operation of the power factor correction circuit to limit the magnitude of its input current to not exceed a first predetermined value.

On-line uninterruptible power system and operation method thereof

An uninterruptible power supply comprising a first switch unit, a charging circuit, a first voltage conversion circuit, a second voltage conversion circuit, a second switch unit and a control circuit is provided. When the uninterruptible power supply performs a battery activation operation, the control circuit controls the first switch unit to provide the AC power received by the uninterruptible power supply to a terminal of a bypass path, controls the first switch unit to provide the output of a battery to the first voltage conversion circuit, controls the second switch unit to electrically couple the output terminal of the uninterruptible power supply to the other terminal of the bypass path, controls the charging circuit to stop charging the battery, and controls the first voltage conversion circuit to perform a DC-DC conversion operation. In addition, a corresponding battery activation operation method is also provided.

Uninterruptible power supply and battery activation operation method thereof

A suspension type sliding bracket having anti-dropping mechanism, the sliding bracket uses a first sliding rail of suspension type to slide on a first bracket, and the sliding bracket uses a second sliding rail of suspension type to slide on a second bracket, a front-end portion of the first sliding rail can provided with a first locating plate, a front-end portion of the first bracket can provided with a first locating post; wherein the first locating post can enter a first slot of the first locating plate, and the first locating post can block a closure portion of the first slot, therefore the first sliding rail can form a first anti-dropping position to stop slide; and the first slot can escape from the first locating post when an extension portion of the first locating plate is pressed.

Suspension type sliding bracket having anti-dropping mechanism

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.

Multi-output power management method

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.

UPS sensitivity of power status parameter adjustment setting method

A method for automatically strengthening energy-saving and electrical safety is disclosed used in a UPS system to perform auto execution of energy-saving and power usage setting. In auto execution, manual setting and auto setting are provided for selection. When entering manual setting, it is to set power environment, time or empirical parameter setting. When entering auto setting, the system will collect power environment, load status and power usage data, and then make sure of priority judgment condition, and then perform data statistic and storage, and then automatically execute Eco Mode or Normal Mode after analysis and judgment. Thus, a user can let the UPS system to collect analyzed data, and then automatically switch the operating mode according to the analysis, enhancing ease of use and lowering the use threshold.

Method for automatically strengthening energy-saving and electrical safety

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.

Power-switching device with interlock mechanism

A control panel having a pivotable connector has a body, a rear cover and a connector. The connector is pivotally mounted inside the body and the rear cover, and has a plug being pivotable and freely aligned with an intended direction. Accordingly, users can adjust the orientation of the connector based on a position on which the control panel is to be mounted, placed or hung, so that the connector of the control panel can be smoothly connected with a connection port of the machine directly or through a connection cable.
