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.
Transformers can achieve the conversion of voltage levels in the power system, and are widely used in long-distance power transmission, effectively solving the energy loss in the process of power transmission.
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,

1. In order to prevent magnetic leakage interference, the distance between the voltage stabilizer and the equipment used should not be less than 2 meters. All kinds of magnetic records, discs, cards, etc. should be kept away from the machine 2 meters to prevent accidental magnetization.
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.
