What is the UPS power feature? UPS power trip What is the reason? UPS power supply can achieve uninterruptible power supply, the power supply of the UPS power supply is important to computer and network devices, the rated capacity of the UPS power supply is in KVA, UPS is generally used for computer and numbers Information system and other occasions. Requires high supply quality load, important emphasis on inverter switching time, output voltage, frequency stability, output waveform, no interference, etc. What is the UPS power supply? The UPS power supply is an important protection of the power supply.
It can continue to supply power to the load after the electricity is suddenly disconnected, so that the equipment prevents the damage to the immediately power failure, and can save data to preserve data Lose. UPS uninterruptible power supply Important applies to some network systems and environments and some network monitoring, etc., and can also be used in some medical systems.
It can solve some problems around the power supply network for some medical systems. It is a new uninterruptible power supply with digital technology. The UPS uninterruptible power supply allows the computer to continue to maintain the computer, can continue to maintain the data within the computer, can protect the data inside, and prevent the normal work of the computer.
Online UPS power supply output sine wave is the smallest, generally less than 3%. Online UPS can truly implement uninterruptible power supply to the load. As long as the internal battery can supply energy to the UPS inverter, no matter whether the electricity is interrupted, online UPS is powered by the inverter.
Therefore, from the process of power supply to the mains, there is no conversion action in the online UPS, which is zero to the conversion time of the load supply. Important Features of the UPS Power 1 After the access work, no noise-free, non-noise-free, non-noise-free, non-noise-free communication. 2 Usually the UPS power supply is in an online working state, obtains power from the main power source as load input, and isolates the surge and electronic interference of the power line.
3 In the online state, the UPS power supply guarantees the smooth load input voltage by compensating the voltage fluctuation of the main power source. Using the transformer tap Trip supply voltage adjustment to achieve the highest work efficiency. 4 During the tap jump, the load temporarily switches to battery power to ensure the sustainability of the load power supply.
5 When the voltage is abnormal or powered off, the UPS power is turned to the battery and outputs the alternating current of the pure sine wave. And in the rated load range is uninterrupted. What is the reason for the UPS power trip? When the main electricity is normal, the high-frequency online uninterruptible power supply is started.
When the UPS power is connected to the boot command, the boot circuit starts working. The main circuit first outputs bypass output. When the CPU detects that the inverter is working properly, a control signal is issued, drive output relay operation, cut off the bypass, turn on the inverter circuit, and complete the power-on process of the UPS.
The phenomenon of leakage circuit breaker (leakage switch) trip will occur during the process. Important causes of leakage protector trip is that the UPS power system has an instantaneous leakage current (non-stable or dynamic leakage current) during startup or switching. Is it when the output relay is operated, when the inverter circuit is turned on, the current in the transition of the sinusoidal power source is turned on in the transition process of the sinusoidal power source in the equivalent resistor R, inductance L, and capacitor C series circuit.
Leakage current that may have large oscillation attenuation during this transition. Among them, L = L1, C = CY. The reason why the UPS power supply is open to open trip, there are few possibilities: 1, it is your switch with leakage protector; 2, it is your switch capacity; 3, it is your load has a short circuit.
The above is the reason for the UPS power supply, the reason for the UPS power trip. There are many UPS varieties available for users, but we generally refer to most of the UPS power supply is static transform, which can be divided into: rear-standing, online, online interactive formula three categories. In the use of the UPS uninterruptible power supply to understand it, you can clear its work process during use, select the appropriate UPS uninterruptible power supply.
