UPS power supply Terms (5)
2022-10-26
Transient recovery time: The time required for the output voltage to return to the specified range when the load is suddenly changed (0-100%, 100%-0), usually in milliseconds (ms).
Filter: A device used to eliminate noise by filtering the input or output to produce pure alternating current.
Shielding: A means of isolating and blocking electromagnetic radiation, using physical principles.
Lightning tube: It is a high pressure protective element used in the input of equipment. If the voltage at both ends is higher than the protection specification value, a short circuit will occur inside the device and the input overvoltage will be absorbed.
Apparent power (APPARENTPOWER) : namely, VA, the change of its power and the RMS (ROOT - MEAN - SPUARE) has absolute relationship of voltage and current.
Data MACHINE: A DEVICE THAT CONVERTS ANALOG SIGNALS FROM A TELEPHONE LINE INTO DIGITAL SIGNALS THAT CAN BE READ BY A PC, OR ANALOG SIGNALS FROM A PC FOR TRANSMISSION OVER A TELEPHONE LINE.
RANDOMACCESSMEMORY (RAM) : stores data needed by the CPU in a dynamic manner.
[SIMPLEMETWORKMANAGFEMENTPROTOCOL simple network management protocol (SNMP)] : It is a widely used network management protocol. It can help network management personnel to manage various devices in TCP/IP networks. In addition, there are only two kinds of commands in the basic concept of FETDH-STORE, which is simple, stable and flexible.
Transient VOLTAGE DROP: SOME will LAST FROM a FEW milliseconds to hundreds of milliseconds. If the voltage drop lasts for a long time or occurs frequently, it will cause computer and electrical equipment failure and reduced life.
Phase-locked circuit: A technical specification of the speed of phase locking, the principle of which is: When the input voltage enters the UPS, the UPS controls the frequency of the output power supply to be the same as the frequency of the input power supply. In this way, the frequency of the input power supply is the same as that of the input power supply, and there is no time difference between the phase and the output frequency. However, if the time difference between the output frequency and the input frequency occurs, the UPS is powered by batteries or does not output power to the load.
Three-phase: the standard power system is a three-phase power supply, the gushan is the first phase of the wave and the phase difference of 120 degrees, and the single phase is a phase of the three phase.
Input voltage range: specifies the range within which the mains power is allowed to change. A larger range indicates a better UPS adaptability
Neutral line: IN a SINGLE-phase power supply system, THE function OF the neutral line is to conduct the feedback current and distribute it in the same area as the socket end and ground.
Distortion: distortion is divided into waveform distortion, voltage distortion, whether volume distortion, are calculated by percentage, the size of the distortion and harmonic, voltage, current and power factor. (HARMONIC)
Mains: that is, we say alternating current (AC), alternating current of 10000 contains: voltage, current, frequency of three, its frequency can be divided into 50HZ (Hz) and 60HZ (Hz) two, voltage distribution, from 100VA-240VA. The NORMAL AC WAVEFORM IS A SINE WAVE, BUT A STEP WAVE IS USED TO FORM A SIMILAR SINE WAVE. This waveform is not suitable for motors or inductive load equipment.
Radio frequency (RADIOFREPUENCY) : This is a kind of electromagnetic, exists in the communication equipment or computer operating equipment, there is a part of the source is by the equipment of the line or the electrical antenna emission, in some cases, because the amplitude is too large, and cause the electrical transmission interruption or computer operating equipment failure and other problems.
Synchronous: The output sine wave power generated by the UPS and the input AC power supply are both sine waves, and the frequency and phase of the two power supplies must be consistent. This is synchronization.
Synchronous converter (SYCHRONOUS) : A type of converter between two power supplies and the load.
Inrush CURRENT: WHEN the ELECTRONIC equipment is connected to the power socket, because the equipment has been shut down for a period of time, the instant power supply will have the current to charge the capacitor in the equipment, so the instantaneous high current of 3~10 microseconds will be generated, and its radiation will be released by the power cord, affecting other electronic equipment.
Surge: a kind of instantaneous high pressure, the high voltage v (amp) from hundreds of thousands of volts (amp) or higher, the duration from thousands of a fraction of a second to hundreds of millions of a fraction of a second, it is a great potential for electronic equipment, light, resulting in the loss of data or electronic parts life cut short, serious can cause damage to equipment or have more serious consequences. There are two causes of spikes: natural ones such as lightning strikes; Second, electronic devices are loaded instantaneously.
Surge suppressor: it can effectively absorb the over high voltage and over current generated by surge, maintain the normal voltage and current to supply electronic equipment, and reduce the harm caused by surge and extend the service life. Because the generation of surge is an occasional phenomenon, it is necessary to install surge suppressor for electrical equipment.
Note: At present, many products replace the surge suppressor with the surge suppressor circuit.
Filter: A device used to eliminate noise by filtering the input or output to produce pure alternating current.
Shielding: A means of isolating and blocking electromagnetic radiation, using physical principles.
Lightning tube: It is a high pressure protective element used in the input of equipment. If the voltage at both ends is higher than the protection specification value, a short circuit will occur inside the device and the input overvoltage will be absorbed.
