Does the voltage instability UPS alarm mean that my UPS does not have voltage stabilization function

When the mains power is normal to 380VAC, the DC main circuit has DC voltage, which is supplied to the DC-AC AC inverter to output a stable 220VAC AC voltage, and the mains charges the current at the same time. When the mains voltage is undervoltage or suddenly loses power at any time, the battery pack feeds power to the DC circuit through an isolation diode switch. There is no switching time from grid to battery power.

When the battery energy is about to be exhausted, the uninterruptible power supply will send out an audible and visual alarm, and stop the inverter at the lower limit point of battery discharge, and the alarm will sound for a long time. The uninterruptible power supply also has an overload protection function, which jumps to the bypass state when an overload (150% load) occurs, and automatically returns when the load is normal. When a serious overload occurs (more than 200% of the rated load), the uninterruptible power supply immediately stops the inverter output and jumps to the bypass state, at which point the front air switch may also trip.

Once the fault is eliminated, just close the switch, restart it and start working again. In order to make the uninterruptible power supply fully work and avoid operating under overload or underload, the load capacity is calculated before the power supply is turned on. The FR-UK type uninterruptible power supply (nominal rated power) has a design load capacity of 80% of the resistive load, which can generally be withstood when the computer load is carried out.

UPS is generally stabilized, but the mains power will still alarm when it exceeds the normal voltage stabilization range of UPS.

This is not with voltage stabilization function, but only general protection - over-voltage and under-voltage protection, power-off protection.

It depends on:1Your Wu Shiwen UPS is that brand: the meaning of the ** used by each brand is different.

2.What is the topology of your UPS: back-up, line-interactive, double-transform. Different topologies have different alarms.

For the backup type or line interactive type, the frequency alarm will be directly transferred to the battery power;

For the double conversion type, usually the frequency range of the main power supply is very wide, and it will not be reported to the police; However, the frequency range of the bypass power supply is narrow, and it is easier to alarm. This is, the UPS can still work normally, but it only sends out an alarm that the bypass AC power supply (frequency) exceeds the limit. This is to protect your load as long as you don't need to switch to a bypass to work properly.

Yes. 1. The high-grade UPS power supply will be used for the load after the mains voltage is stabilized, which is equivalent to an AC mains voltage regulator.

When the mains power is interrupted, UPS immediately converts the power from the battery in the machine into a stable 220V through the inverter to continue supplying power to the load.

Therefore, it has the function of voltage regulation.

2. The low-grade UPS power supply only connects the mains power directly to the load, and does not have the function of AC voltage stabilization.

When the mains power is interrupted, UPS immediately converts the power from the battery in the machine into a stable 220V through the inverter to continue supplying power to the load.

Therefore, there is no AC voltage stabilization function for the mains, but it has a voltage stabilization function for the inverter AC.

Both UPS power supply and regulated power supply have voltage regulation functions, but the two are different products, but they play a similar role in voltage regulation. The difference can be seen in a brief introduction to the following two products:

A stabilized voltage supply is an electronic device that can provide stable alternating or direct current to a load.

UPS (Uninterruptable Power Supply) is an uninterruptible power supply. It has four major functions: 1. No power outage function (to solve the problem of power outage of the power grid), 2. AC voltage stabilization function (to solve the problem of violent fluctuations in network voltage), 3. Purification function (to solve the problem of power grid and power pollution), 4. Management function (to solve the problem of AC power maintenance).

1. At night, the load is at the peak of the day, so the voltage is very low, and the computer often shuts down or restarts automatically, which will lead to the loss of files and paralyze the system, and in more serious cases, it will burn the power supply or motherboard. In this case, you must install voltage regulator equipment, and the voltage regulator and UPS you mentioned can solve these problems.

2. The working principle of the voltage regulator is to preset the output voltage. When the output voltage changes, the sampling circuit obtains a sample and compares it with the reference circuit to judge the change of the output voltage, and judges the amount of change, thereby controlling the work of the adjustment circuit, and prompting the adjustment circuit to adjust the output voltage to change to low or high until the output reaches the preset voltage.

UPS is also called AC uninterruptible power supply, which can ensure that the computer system continues to work for a period of time after a power outage so that users can save the disk urgently, so that you will not affect your work or lose data due to power failure. It mainly plays two roles: one is emergency use, to prevent sudden power failure and affect normal work, causing damage to the computer; The second is to eliminate "power pollution" such as power surges, instantaneous high voltage, instantaneous low voltage, wire noise and frequency excursion on the mains, improve power quality, and provide high-quality power supply for computer systems.

In principle, UPS is a power protection device containing energy storage devices, with inverters as the main components, and stable voltage and frequency output. It is mainly composed of rectifier, battery, inverter and static switch.

Third, fourth, the regulated power supply, mainly to stabilize the voltage. It cannot be charged. That is, when the power is out, the voltage regulator will also be powered off immediately, which can lead to the data cannot be saved in time and the computer fails. **Cheaper than UPS.

UPS is mainly a function of charging and storing electricity. That is, when there is a power outage, the UPS can use its own stored electricity to power the computer. But the time is shorter, about 30 minutes, so that users can save important information in time.

**A little more expensive than a regulated power supply. According to your actual situation, it is recommended that you configure a household UPS power supply, which is very simple, has a voltage stabilizing effect and continues to invert power supply to 1 hour after power failure, which is very easy to use. ** Not too high less than 300, can solve all your concerns.

It is highly recommended to purchase Shanton uninterruptible regulated power supply.
