How many types of UPS uninterruptible power supply are there?

I think it would be better to consult a more professional company in an industry like Venture Feida for such a professional problem.

Pure mains power is the standard sine wave, which is the most ideal waveform; The higher harmonics of square waves are more, which will affect the work of precision instruments; The stepped wave is a special form of square wave, which is between the square wave and the sine wave, and the UPS output of this waveform is suitable for loads with less stringent power requirements. UPS is divided into small UPS according to capacity: less than 10KVA; Medium UPS:

More than 10kva, less than 100kva; Large UPS: 100KVA or more. The wide variety of UPS is not very different in the battery power state, all of them are inverter output, and the main difference is in the working state in the mains state.

At this time, the ** type is still the output of the inverter, and there is an independent charging circuit; Online interactive (or ** interactive or online interactive) is direct output or mains power coupled output through transformer, and the inverter is the charger; The backup type is a direct output or a mains power coupled output through a transformer, and the inverter does not work at this time and has a separate charging circuit.

UPS power supply can be divided into two types of operation: dynamic and static. Dynamic UPS is composed of rectifier, battery, DC motor, diesel (gas) engine, flywheel and generator set, which is an earlier form of UPS, which has the advantages of stable and reliable maintenance technology and relatively simple maintenance technology. However, the equipment is large and bulky, low efficiency, and noisy, and has not been used much.

Before purchasing a UPS power supply, confirm the following issues:

Clarify the condition of the equipment, the power environment, and the desired power protection purpose.

For the small power equipment with built-in switching power supply, the backup UPS can generally be selected, and the first interactive or ** UPS should be selected in the place where the electricity environment is harsh, and the equipment that does not allow intermittent time or time requires sine wave alternating current, can only choose the first UPS.

Determine the nature of the load, is it a resistive capacitive load, an inductive load, or both?

For inductive loads such as fans and motors, UPS should be configured according to more than 3 times the rated power of the equipment, and if the inductive load is equipped with a frequency conversion device, it can be configured according to 1:1.

What is the total power of the current load?

Purchasing should be based on the load power, not the capacity of the UPS to purchase the battery. When buying a UPS power supply, it is necessary to figure out the load power factor of the UPS power supply, KW = power factor * KVA, the greater the visible factor, the stronger the load capacity of the UPS power supply.

Will there be a significant increase in load in the near future?

If there is a large amount of load to be added in the future, it is recommended to choose a UPS with good scalability. Aerospace Burke M series modular UPS, as long as the rack for expansion is configured in the early stage, it can achieve first-class expansion, convenient and fast. Of course, it is also recommended that the battery capacity and battery line are matched according to the total load in the later stage, so as to avoid unnecessary trouble for later maintenance due to the battery discharge time being too short or the battery line being thin when the load increases.

Is there a limit to the installation space?

For the installation space, be sure to measure and arrange in advance, taking into account the main unit, battery and necessary maintenance space.

Other Notes:

If the machine is installed on a non-first floor, the load-bearing situation of the floor must be considered, and the weight of the UPS host and battery must be taken into account, and the floor should be reinforced if necessary. For the case that there is no power outage for a long time, you can manually turn to the battery discharge for a period of time, which can prolong the service life of the electromagnetic and find the problem battery in time.

If the UPS power supply is purchased to protect the ordinary computer with important information, then it must be ensured that the UPS can provide a protection voltage of less than 300V, so that in the mains.

In the event of a power outage, UPS can instantly complete the process of switching to the backup power supply, so that the computer can still run smoothly in the event of a short-term power failure, without data loss and system shutdown. In the case of interruption of the mains power supply for a long time.

In addition, the UPS device can start the power management software to achieve a safe computer system shutdown process and ensure the integrity of the data; In this way, UPS not only protects the hardware of the PC, but also protects the data within the hardware. If you choose.

The purchased UPS is to protect the network server, so the purchased UPS should not only have the functions of anti-surge voltage, rechargeable battery, etc., but also have the function of preventing data line surges to ensure that the UPS is stopped in the mains power grid.

It can run at least 5 minutes under full load conditions in the case of power, so as to avoid the network switching equipment from the interference of the mains, and the UPS of the server should preferably have intelligent battery management function.
