feature of product

• Low frequency design, the output can withstand five times the current

Generally, high-frequency UPS can only withstand about 3 times the change in current. Excessive current will usually cause the high-frequency UPS components to be unable to withstand and be damaged. The UPS3 uninterruptible power system is recommended to be a UPS with low-frequency design, which can withstand five times the current! It has good load capacity for environments and equipment with high instantaneous starting current (inductive)!

• Built-in ultra-isolation protection module

Generally, UPS must be equipped with an optional isolation protection module to solve the problems of leakage current and high and low voltage differences between equipment caused by poor grounding. This UPS uninterruptible power supply system is recommended for high-stable protection design. It has a built-in ultra-isolation protection module, which can achieve effective isolation and simultaneously solve various power conditions such as system leakage current, lightning strikes, noise, neutral line disconnection, etc.!

• High stability rectification design

In order to achieve high stability and quality power output, models above 100KVA adopt 12-pulse fully controlled rectification. In addition to being more stable than ordinary 6-pulse rectification, it can also reduce harmonic current distortion and increase power efficiency.
, making the system rectifier circuit achieve higher quality and excellent stability.

• Smart charging and temperature compensation design

In addition to fully charging the battery in a short period of time, the charging circuit can also detect the high and low temperature of the battery during charging and automatically adjust the current flow to maintain the battery charging at normal temperature to protect battery life and safety!

• DC cold start function, battery slow start protection circuit

Generally, large three-phase UPS rarely have DC cold start function, because if the battery fuse is turned on when there is no mains power, its unlimited current will cause the capacitor to burn out.
. This UPS system contains a set of battery slow-start protection circuits that can protect and limit the current. Therefore, it can achieve the DC cold start function when there is no mains power. It can make the UPS uninterruptible power system recommended for direct use in emergencies without mains power. .

• Plug and play modular design

Both the rectifier and inverter adopt plug-and-play modular design. When the UPS fails and needs to be repaired, the judgment can be completed in a short time and the damaged module can be quickly replaced without wasting on-site repair time.

• N+1 parallel connection function (up to 8 units can be connected in parallel)

In addition to being able to flexibly increase the load capacity, it can also automatically share the current output to the back-end load when two (or more) hosts are connected in parallel. As long as any UPS fails, the other normal hosts will automatically connect to supply the entire load. At this time, repairing the faulty UPS host will not affect the power consumption of the back-end load!

Operation interface features

• Complete operating interface and alarm display

LED+LCD panel: Provides 24 sets of LED lights for UPS status display, allowing users to see clearly on the panel. At the same time, you can set UPS parameters and query various real-time information on the LCD panel. If an abnormality occurs in the UPS, the system also provides multiple sets of abnormal status archiving functions.

• Modular machine board, quick repair design

UPS boards are modular in design and integrated behind the cabinet panel. When a UPS fault needs to be repaired, you only need to open the panel to see it at a glance. During maintenance, you can quickly and easily determine the cause of the fault and replace the damaged board.

Classification theory of uninterruptible power supply system

The uninterruptible power supply system (or UPS, Uninterruptible Power Supply) continuously provides backup AC power to electrical load devices in the event of power grid abnormalities (such as power outages, undervoltage, interference or surges (inrush current)), maintaining A device for the proper functioning of electrical appliances. Usually, the uninterruptible power supply system is used to maintain the uninterrupted operation of critical commercial devices or precision instruments such as computers (especially servers) or switches to prevent loss of computer data, interruption of telephone communication networks, or loss of control of instruments.

In North America, the large-scale UPS used in data centers is mainly three-phase 480V, which is different from the three-phase 208V mains power supply. The European data center uses the same three-phase 400V as the mains power supply.

Power grid abnormality
The use of uninterruptible power systems is to cope with the following situations that may occur in the power grid:

 

• Power outage (power grid stops working, no voltage output)
• Voltage drop (also known as sag, the grid voltage is lower than the nominal voltage 15%-20%, which may last for several seconds)
• Surge (also known as surge, surge, the grid voltage is momentarily higher than the nominal voltage by more than 10%, lasting for several seconds)
• Continuous undervoltage
• Continuous overvoltage
• Line noise (radio frequency or electromagnetic interference introduced due to poor line blocking)
• Frequency drift (grid frequency deviation caused by generator instability)
• Switching transient (also called transient, a voltage deviation caused by the switching or discharge of an electrical device, sometimes up to 20,000 volts, but lasting only a few nanoseconds)
• Harmonics (interference to the alternating current sinusoidal waveform caused by electrical devices with nonlinear characteristics in the power grid)

How the uninterruptible power supply system works
backup

The backup type is also called offline uninterruptible power system (Off-Line UPS). It is only a "backup" UPS. The mains power directly supplies power to the electrical devices and also charges the battery (Normal Mode). Once the quality of the mains power supply deteriorates, When the power supply stabilizes or fails, the mains power circuit will be automatically cut off, and the DC power of the battery will be converted into alternating current to take over the power supply task (Battery Mode) until the mains power returns to normal. "UPS will only intervene in power supply when the mains power fails." However, the AC power converted from DC power is a square wave and is limited to powering capacitive loads, such as computers and monitors. If the Inverter is a sine wave inverter, it can supply power to inductive loads, such as motors and electric fans.

Online staggered

Online interleaved UPS is also called online interactive or line-interactive UPS. The basic operation method is the same as that of offline UPS. The difference is that although online interleaved UPS does not intervene in the power supply throughout the entire process, it does It monitors the mains power supply status at all times and has its own voltage boost and voltage reduction compensation circuit. When the mains power supply status is not ideal, it can make immediate corrections to reduce unnecessary "Battery Mode" switching and extend battery life.

Online

 

The operation mode of the online uninterruptible power supply system (On-Line UPS) is that "mains power and electrical devices are isolated, and the mains power will not directly supply power to the electrical devices." Instead, it will be converted into direct current when it reaches the UPS, and then The battery is divided into two channels, one channel charges the battery, and the other channel switches back to alternating current to supply power to electrical devices. When the quality of the mains power supply is unstable or there is a power outage, the battery switches from charging to power supply, and does not switch back to charging until the mains power returns to normal. "UPS is fully involved in the entire process of electricity consumption." Its advantage is that the output waveform is the same sine wave as the mains power, and it is pure and noise-free, and is not affected by unstable mains power. It can supply power to "inductive loads" such as electric fans, as long as the UPS output power is sufficient. Under the premise, it can supply power to any device using mains power.
