Problems to be paid attention to when UPS is equipped with regulated power supply
(1). The regulated power supply must provide a reliable mains overvoltage input protection function. Except that the parametric voltage stabilizer can provide 220V regulated power supply to the load for a long time when the mains input voltage is as high as 300V under extreme working conditions, the upper limit of the mains power allowed by other several AC regulated power supplies is within 260V. Moreover, the parametric voltage stabilizer has a sine wave purification effect: when a 50Hz sine wave or even a square wave with severely distorted waveform is input at its input terminal, it will send out a sine wave power supply with less waveform distortion at the output terminal. Therefore, it has two-way anti-interference ability, which can not only suppress the influence of the interference from the mains power grid on the load, but also suppress the pollution of the power grid caused by the interference generated by the load. But its frequency adaptation range is narrow, and it is only suitable for power supply systems with stable grid frequency.
(2). Since the electronic tube type and magnetic saturation type AC voltage stabilizer will have an instantaneous high voltage lasting for about 1 to 2 seconds at the moment of starting up, it is easy to induce a failure in the UPS power supply system. Therefore, these two types of voltage stabilizers The device should not be connected to the power supply system of UPS uninterruptible power supply.
(3). The regulated power supply should have the advantages of wide voltage range and strong anti-interference ability. A UPS is an uninterruptible power supply. Mainly to solve the problem of frequent power outages. For areas where the mains voltage is often low and power outages are not frequent, just add a regulated power supply. Do not add a stabilized power supply, only add UPS, can not solve the problem of low voltage. The connection of the two in series will not cause any harm to the UPS.
