Voltage stabilized power supply compared to conventional power supply
(1) Fast response speed. Due to the selection of all high-speed linear electronic devices, instantaneous sampling, instantaneous implementation, control response speed is extremely fast, milliseconds can be completed below the level of adjustment, so that the output voltage quickly return to the rated voltage neighborhood. Therefore, for high-frequency interference and noise suppression, millisecond interference has a purifying effect, which is the general regulated power supply can not do.
(2) Wide input voltage range. Input voltage changes up to 30% ~ 50% or more, and can be adjusted symmetrically, the wider the range to provide more energy to repair. How much control voltage value is mainly determined by the demand, from the economic and practical point of view, take (8 ~ 10)% is appropriate.
(3) High accuracy of voltage stabilization. With the different ways of generating reference voltage, the effect of voltage stabilization can be up to 1%, 0.1%, 0.01%. Different accuracy of voltage stabilization, applicable to different requirements of the occasion. 1% for general voltage stabilization requirements of the occasion; 0.1% for the laboratory or important industrial equipment; 0.01% can be used for instrumentation calibration.
(4) Characterized by green power supply. The method first corrects the waveform of the grid voltage, corrects it into a good sine wave, and then supplies power to the load, and the amount of repair energy is decided by the need. Since the essence of the method is the correction of the grid waveform, the distortion of the corrected waveform is generally less than 1% ~ 0.5%, therefore, the method of voltage regulation is green.
(5) It has a certain environmental nature. If the input voltage is unchanged, due to the different nature of the load caused by the output voltage changes, in a certain harmonic range using the corresponding change in the control voltage to make the output voltage unchanged. Because the control voltage has the isolation effect, it can't affect the input voltage, therefore, the voltage stabilization method has a certain environmental protection nature.
(6) High working efficiency. The working principle of this power supply is that small power controls large power, which has high efficiency. The capacity of the output voltage is mainly taken from the power grid, and the control voltage is generally the part of the grid voltage that deviates from the rated voltage, so it only needs to consume the power to manufacture the control power supply, so the efficiency is very high.
