The backup time is the maximum power supply time that the UPS power supply can provide to the computer and other equipment after the mains power failure. The greater the main power of the equipment you bring, the shorter the actual power supply time. The backup time refers to the maximum power supply time under the rated power.
The single-phase voltage stabilizer is composed of a contact auto-coupling voltage regulator, a drive rectifier circuit, an automatic control circuit, etc. The working principle is: when the grid voltage is unstable or the load changes, the automatic sampling control circuit sends out a signal and drives the drive circuit, adjusts the position of the auto-voltage regulator driver, and adjusts the output voltage to the rated value and reaches a stable state with overvoltage, Under-voltage,
The voltage stabilizer is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator. By automatically adjusting the coil turns ratio, the output voltage is kept stable. The voltage regulator with larger capacity also works on the principle of voltage compensation.
What are the components of a stabilized power supply? A DC stabilizer is mainly composed of a power transformer, a rectifier circuit, a filter circuit and a stabilized circuit. The functions of each part are as follows.
The overload operation of the transformer means that the transformer exceeds the rated current value when it is running. The long-term severe overload operation of the transformer will not only reduce the efficiency of the transformer, but also increase the copper loss and cause equipment damage, which is not conducive to the economic and safe operation of the transformer.
1. Connect the input of the automatic power regulator to the power distribution board, and install a fuse that meets the power guarantee rate of the instrument on the user power distribution board to ensure the safety of electricity. 2. Connect the power supply of the electrical equipment to the output terminal of the fully automatic power supply voltage stabilizer.
