An Overview on UPS Technology

An Overview on UPS Technology

Uninterruptible power supplies (UPS) is a device used to supply power to the battery backup power supplies in the event of a power outage. So you have enough time to backup or off (Shutdown) device servers. To prevent damage that may occur to your precious data files in the event of fire suddenly.

So before you decide to opt for a power supply (UPS), you should know the basic structure of the UPS. (UPS) to be used in that decision. What kind of machine is suitable for use. And most budget

Select the following to study power supply (UPS) applications.

Offline (Standby) UPS Technology

In normal conditions (Standby mode / Normal Mode) electricity will flow directly through to electrical equipment. The only integrated RFI Filtering only to help filter noise. And when under power. Or a power outage or exceeds a certain value, such as (220 +/- 15%) control circuit inside the UPS detects and ordered the circuit DC / AC Inverter operation (Inverter Mode / Battery Mode) for power conversion (DC) from. battery into alternating (AC) to be supplied to the electrical equipment. * By switching waveforms of this inverter circuit. It can be a rectangular waveform (Step wave) waveform or a sine wave (Sine wave) as with a regular electrocardiogram Electricity Authority of Thailand. After that, if the electric power returned to normal. The control circuit inside the UPS, it will instruct the Switch to connect directly to the source of electrical power. To supply power to the device. During the transfer, the Switch with electrocardiogram missing about 2 ms, which is called the Transfer Time.

Advantages

- Low prices - small noise when in Standby mode.

- High performance

cons

- Protect electrical equipment safe from electrical conditions Spike, Surge limit.

- Controls the voltage supplied to the device is limited to approximately +/- 10 ~ 15%.

- Can not get a wide voltage input. Usually around +/- 10 ~ 15%.

- An electrical waveform missing about 2 ms during the transfer of power to a regular supply of batteries.

- There is no backup system in case the Inverter waste or consume more electricity than normal in awhile.

Line Interactive UPS Technology

UPS also is similar to the type of UPS Offline (Standby) UPS adding circuit to automatically adjust the pressure. To make the power supply voltage to the input has widened approximately 220 +/- 20 ~ 25%, while the output voltage can be controlled to within +/- 10% in addition to the 220. you can also filter out signal interference, Spike, Surges, Sages better with a filter function of normal (Standby Mode / normal Mode) to supply power to the device. Through the integrated automatic pressure adjustment. (Stabilizer / AVR) and circuit (RFI Filtering) and when under power. Or a power outage or exceeds a certain value, such as (220 +/- 20 ~ 25%) control circuit inside the UPS detects and ordered the circuit DC / AC Inverter operation (Inverter Mode / Battery Mode) for power conversion (DC. ) from the battery into alternating (AC) to be supplied to the electrical equipment. * By switching waveforms of this inverter circuit. It can be a rectangular waveform (Step wave) waveform or a sine wave (Sine wave) as with a regular electrocardiogram Electricity Authority of Thailand. After that, if the electric power returned to normal. The control circuit inside the UPS, it will instruct the Switch to connect directly to the source of electrical power. To supply power to the device. During the transfer, the Switch with electrocardiogram missing about 2 ms, which is called the Transfer Time.

Advantages

- Costs and lower prices True Online.

- Small silent when it is in Standby mode.

- Protect electrical equipment from power problems better than Offline.

- High performance

cons

- Protect electrical equipment safe from electrical conditions have limited compared True Online.

- Controls the voltage supplied to the device is limited to approximately +/- 10%.

- An electrical waveform missing about 2 ms during the transfer of power to a regular supply of batteries.

- There is no backup system in case the Inverter waste or consume more electricity than normal in awhile.

True Online Double Conversion UPS Technology

UPS type To protect electrical equipment best. Because normal (Normal mode) will convert alternating current (AC) to direct current (DC) with integrated AC / DC rectifier) then converts the direct current (DC) to return to AC (AC) circuit (. DC / AC inverter) * is a sine wave waveforms (sine wave) as with a regular electrocardiogram electricity Authority of Thailand. The electrical supply to another. Making it possible to control the voltage (220 +/- 1%) has continued to be no.

Advantages

- To protect electrical equipment in all cases.

- A system to monitor themselves. And transfer the electricity to power the device with the Automatic Bypass Mode In the event of a malfunction. Or use a power overload limit.

- Wave power is lost during a power outage (Zero Transfer time DC to AC).

- The ability to control the voltage supplied to the electrical equipment is excellent (220 +/- 1%).

cons

- The high price compared to other types.

N + X Parallel Redundancy UPS Technology

Technology N + X Parallel Redundancy is an additional feature. For Type True Online Double Conversion UPS to protect electrical equipment from overseas. And most perfect right now. Because users can type power supply. The parallel additions For purposes of the following two reasons.

1. To increase the rated power of the power supply, such as a two-fold or three-fold from the previous example.

2. To replace a broken immediately as a N + X 2 + 1 and so on.

To increase the rated power

You can take a power supply that supports N + X Parallel Redundancy parallel to both the electrical power input and the output. To increase the rated power is two times or three times the machines to be connected in parallel to increase, such as the size 6kVA two machines connected in parallel to achieve large capacity 12kVA (6kVA + 6kVA = 12 kVA) or size. 20kVA three were connected in parallel to achieve large capacity 60kVA (20kVA + 20kVA + 20kVA = 60kVA) uPS, etc., all brought together in parallel. To lighten the load on the power of each machine. With an average power Electricity is paid equally by each controller (CPU Controller) each machine will be connected together. Through Cable In order to control each device coordination (Hot Synch) virtual machine.

In order to replace a broken machine immediately.

You can take a power supply that supports N + X Parallel Redundacy connected in parallel by N equals the power supply. The least that can supply electric power to the power supplies were adequate. Such as electrical power demand is equal to 12kVA be used. Uninterruptible Power 6kVA 2 units connected in parallel, N = 2 and a power supply, an additional one X = 1 to the parallel added to each machine power, the size 4kVA as 4x3 = 12kVA, so if a machine. backup one machine damaged the power supply, while the remaining two, it can also power to the electrical equipment has continued without interruption. You can bring it back Electrical equipment that is malfunctioning Out to be repaired immediately. Without prejudice to the power at all. The UPS 2 units remaining. Helped to power the machine 6kVA to 6x2 = 12kVA power to be supplied to electrical equipment as before. UPS to be connected in parallel. It is still more features. Of True Online Double Conversion UPS in its entirety as Automatic Bypass, Manual Bypass, Zero transfer time, etc. by as True Online Double Conversion UPS systems.

Advantages

- A system of continuous power with high stability now.

- To protect electrical equipment in all cases.

- A system to monitor themselves. And transferring electricity to power directly to the device in case of malfunction. Or use a power overload limit.

- Wave power is lost during a power outage (Zero Transfer time DC to AC).

- The ability to control the voltage supplied to the electrical equipment is excellent (220 +/- 1%).

- Can increase the power output to meet the growing electricity consumption in the future.

- A modular hunting (Modular) can increase or decrease. The power supply out of the system immediately. For expansion Or maintenance Without prejudice to the power continuously.

cons

- The high price compared to other types.
