The line-interactive UPS inverter does not output power to the load under normal conditions of the main AC mains and is in a hot backup state, which is the fundamental difference between it and the backup UPS. The inverter can transmit power in both directions, so the inverter can charge the battery at the same time, which increases the charging power capacity of the UPS when the mains power is normal and reduces the conversion time when the mains power fails. In terms of circuit structure, it belongs to the parallel power adjustment method, and the output power is mostly below 5kVA.
The high-frequency online UPS is often referred to as a line of service or LOS UPS for short(1kva line interactive UPS price: line interactive UPS vs online UPS). The term LOS UPS is often used to describe the UPS unit that is used to provide a UPS backup for a business or organization. In the UPS business, the LOS UPS is often a UPS line of service that is designed to provide power and protection to computers, servers, and other computer equipment.
line-interactive UPS 10kVA
When you are purchasing a LOS UPS line of service or a LOS UPS for your business you will need to purchase both a high-frequency UPS and a line-interactive UPS. The high-frequency UPS is a device that connects directly to the computer that needs UPS power.
If you are considering purchasing the high-frequency online UPS for your business, you will want to do your research and find a company that can provide you with a high-frequency online UPS line of service. The line-interactive UPS 10kVA is another type of UPS that is designed to provide a UPS backup for an organization or business.
The line-interactive UPS 10kVA is designed for backup protection to critical applications. The line UPS online is designed for use with the high-frequency online UPS line of service. The line UPS line of service will provide a UPS backup for your server, network, and other computer equipment.
There are many different models of the line-interactive UPS that can be used for your business or company(online UPS 2kva: ups manufacturers). The online UPS line of service is available in many different models. The line UPS line of service is also available in many different sizes.
The line-interactive UPS line of service can be purchased through many different companies. The line-interactive UPS is designed for use in an office building or a commercial building.
The line UPS line of service is often used in an organization that is concerned about the security of the business or company's systems. The line UPS line of service is often used to provide a backup for computers, servers, and other computer equipment.
The line UPS line of service is often used in an office building or commercial building to provide a UPS backup for critical applications. The line UPS line of service is often used to provide a backup for computers, servers, and other computer equipment.
Input switch: When the mains power is normal, the switch is turned on; when the mains power fails, the switch is automatically turned off to prevent the inverter from feeding back to the grid.
Automatic voltage stabilization: When there is a mains power supply, it can roughly stabilize the voltage and absorb some grid interference. The voltage stabilization method is roughly the same as the backup type. Relays are often used to change the transformer tapping method. When the input voltage is high, the transformer will step down, and when the input voltage is low, the transformer will step up, and the output voltage regulation accuracy is 5%~10%.
Inverter: This inverter has a two-way conversion function. When there is the mains power supply, it is an AC/DC rectifier to charge the battery; when the mains power fails, it is converted to a DC/AC inverter, powered by the battery, and UOS continues to supply power to the load. The output voltage waveform can also be a quasi-sine wave, but due to the large output power, the load may have equipment that requires the input voltage to be a sine wave, so the inverter output voltage of a line-interactive UPS 10kVA is mostly a sine wave.
When the electricity is normal, the work efficiency is extremely high, up to 98 or more.
The input power factor and input current harmonic components depend on the nature of the load, and it does not add harmonic interference to the power grid.
The output capacity is strong when the mains power is normal, and it is suitable for loads of various impedance properties. There are no strict restrictions on the load current crest factor, surge factor, output power factor, and overload capacity.
The output voltage accuracy and stability are poor, but it can meet the power supply requirements of general loads.
The inverter is directly connected to the output terminal of the UPS and is in a hot backup state, which has a certain degree of suppression of input voltage spikes and has a simple circuit, low cost, and high reliability.
Because the input switch has an off time, the UPS output still has a conversion time but it is shorter than the backup type, generally 4~6ms. If an inductance is connected in series between the input switch and the automatic voltage regulator, when the mains power fails, the inverter can supply power to the load immediately, which can avoid the short circuit caused by the inverter feedback to the grid when the input switch is disconnected. Dangerous (inverter reverse protection function), at the same time it can shorten the line-interactive conversion time to zero, and increase the anti-interference ability, but this will reduce the input power factor of the control.
Backup and line-interactive UPS do not have the problem of setting a static bypass switch separately. For double conversion (online) UpS, because the inverter output capacity is limited, when the load current is overloaded or the inverter fails, the UPS will switch from the mains inverter state to the static bypass and the mains directly supply power to the load. Back-up and line-interactive UPS, when the mains power is normal, the inverter does not work or works without load, and will not damage the inverter. The voltage stabilization link of these two UPSs is simpler and more reliable than double conversion UPS has high reliability and strong resistance to overload and impact, which is equivalent to an online bypass structure.
