A few days ago, the thunder, my computer power and network card hack, and power amplifier speaker received voltage regulator, nothing.I wonder if UPS has any voltage stabilizing function? In thunder, voltage, current suddenly too big, will automatic voltage regulation?
UPS power supply system consists of five parts: input to the main road, bypass, battery power supply circuit, rectifier AC/DC transform (REC), inverter DC/AC transform (INV), and the inverter output bypass switching circuit and a storage battery. The regulator function system is usually done by the rectifier, rectifier SCR or high-frequency switch rectifier itself can be according to the change of electric control output amplitude function, so when external power is changed (the change should meet the requirements of the system), the rectifier output voltage amplitude unchanged. The purification function is completed by the energy storage battery, because the rectifier can not eliminate the instantaneous pulse interference, and the rectified voltage still has interference pulse. In addition to storing DC Direct Energy, the storage battery is like a large capacity capacitor for the rectifier, and its equivalent capacitance is proportional to the capacity of the energy storage battery. Because the voltage at both ends of the capacitor can not be mutated, that is to use the smooth pulse characteristics of the capacitor to eliminate pulse interference, and play a cleaning function, also known as interference shielding. The frequency stability is achieved by the converter, and the frequency stability depends on the stability of the oscillation frequency of the converter.
The general on-line UPS power supply with a voltage stabilizing regulator with lightning protection effect of 1 but is not know? General voltage regulator and power frequency UPS power supply, because it has isolation transformer, it has the function of lightning protection!
Now the general UPS have steady voltageSantak's TG series is not available. There are other inexpensive machines, tooGeneral prices are, 175V to 275VWell, it's 145V to 300V
The UPS power supply has a voltage stabilizing function.UPS (Uninterruptible, Power, System), that is, uninterruptible power supply, is a kind of energy storage device, inverter as the main component of constant voltage constant frequency uninterruptible power supply. Used primarily to provide uninterrupted power supply to a single computer, computer network system, or other power electronic equipment. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC power regulator, it is also the built-in battery; when the power interruption (outage), UPS will immediately machine battery power through the inverter conversion method continue to supply 220V AC power to the load, the load to maintain normal working load and protection of software and hardware is not damaged. UPS devices usually provide protection against too large voltages and too low voltages.
The power amplifier and your 1000W regulator are transformers, and the primary has no electronic components. Even if it is struck by lightning, the secondary is isolated and the electrical equipment is ok. Computer power supply is an electronic transformer, the primary has many electronic components, once caught, it is very easy to break.Good point UPS with constant voltage, over-current protection circuit, but like computer power, are used in electronic transformer (the advantages of high efficiency, etc.) are simple (lightning protection measures is the use of varistor), but the lightning electromagnetic pulse generated by high pressure too strong...Most security measures are impossible to guard against, lightning when pulled out of electric power equipment and external connection.
