UPS
UPS system, namely uninterruptible power supply system, is a power supply protection device with energy storage device, inverter as the main component and voltage and frequency stabilization output. In the application of computer and network system, it mainly plays two roles: first, emergency use, to prevent the sudden power failure of the power grid from affecting the normal work and causing damage to the computer system; The second is to eliminate the "power pollution" such as surge, transient high voltage, transient low voltage, transient overvoltage, wire noise and frequency offset on the municipal power grid, improve the quality of power supply, and provide high-quality power supply for computer systems.
How to choose the most suitable UPS equipment？
Steps to quickly purchase UPS equipment
1、Click to consult
2、Get in touch with our engineers
3、Determine the design scheme
Most People Ask :
What are the various backup power solutions?
First understand your power requirements.
Find the VA rating of the inverter you need.
Find the battery size you need.
What about bigger appliances?
Long standby demand and inverter voltage.
Inverter battery calculator.
Offline UPS, also known as standby UPS or battery backup, is a cost-effective option. A better offline UPS system switches to the battery fast enough to prevent power supply anomalies and short interruptions. Offline UPS can prevent most spikes, but it cannot maintain perfect power during slight dips and surges.
How to confirm the scheme design of UPS equipment?
Quick confirmation of several major steps of UPS equipment scheme design
1、Communicate needs with engineers
2、Review the design scheme
3、Determine the design scheme
Most People Ask :
Basic structure
(1) Rectifier: circuit for converting AC to DC (2) Inverter: circuit for converting DC to AC (3) Bypass: circuit for directly outputting AC (4) Switch: circuit for switching between inverter outputs and bypass output Figure 3 shows the basic structure of UPS.
Any online dual conversion uninterruptible power supply (UPS) system has four main components: rectifier; UPS battery; Inverter; And static bypass switch.
There are four main components in the UPS system: 1) UPS battery; 2) Rectifier; 3) Inverter; 4) Static bypass switch.
How do I select the components of the UPS?
Three points to ensure rapid procurement of UPS equipment components
1、Click to consult
2、Contact the Engineer
3、Confirm requirements
Most People Ask :
To select a suitable UPS, be sure to understand the business requirements, power size requirements, and how long your backup system must last during downtime. UPS selection starts with planning and commercial purposes.
The three main types of UPS system configuration are online dual conversion, online interaction and offline (also known as backup and battery backup). These UPS systems are defined by how power passes through the unit.
No, the Smart UPS SURT series (10Kva or lower) can only be turned on by connecting the working battery.
How does the UPS work?
Three points to ensure the safe operation of UPS equipment
Most People Ask :
You just need to plug the power cord of the PC and screen into the UPS, then plug in the UPS, turn it on, turn on your computer, and you can start using
The battery is fully charged at the factory. However, it is recommended to charge the battery for at least 8 (eight) hours before using the UPS, as energy loss may occur during transportation or long-term storage. To charge the battery, simply plug the UPS into an AC outlet.
“Operation time” refers to the time when UPS provides power in case of mains power interruption. The standard battery operation time of ordinary UPS is about 5 to 10 minutes under full load and about twice under half load.
How to detect the quality of UPS equipment?
Quality Key Points of Uninterruptible Power Supply Equipment
1、 Complete and pass the test required for the energy storage equipment.
Most People Ask :
An effective UPS usually includes the following features: a regulated output voltage with low harmonic distortion, which is not affected by input voltage or load changes. Input current with reduced harmonic distortion. Low level of electromagnetic interference and noise.
Just unplug the UPS backup power supply from its power supply, and you can directly test its function. This is when many units begin to beep, once they “realize” that the battery cannot maintain its output when disconnected from the main power supply.
Usually, repeated alarms, flashing panel lights, and strange terminal displays are symptoms of UPS battery failure.
How to choose the transportation and packaging mode of UPS equipment?
2 points to ensure the transportation and packaging safety of UPS equipment
1、Complete and pass various transportation tests
2、Reinforce the packaging of household transport equipment
Most People Ask :
Unlike urgent parcels that are almost always sent by air plane (which can be very expensive), UPS Ground parcels and parcels are mostly transported nationwide by trailers and freight trains.
UPS ® 3rd Day Select: This transportation option is most suitable for delivery with low time sensitivity. Ensure delivery before the end of the third working day. UPS ® Ground: This is the most economical choice for regular shipments – shipments that do not add time value to customers.
How is the UPS installed?
Three common UPS installation methods
Most People Ask :
Any hard wired UPS should be installed by a licensed electrician, preferably one who is familiar with the specific model. Although the smaller Plug and Play UPS allows users to install it, it is still wise to have another pair of eyes check the work under these circumstances.
Your UPS should be installed in a temperature control room without any windows or humidity. Ideally, it will allow the temperature control system to operate independently of other HVAC systems in your facility.
However, with proper maintenance, UPS can operate safely and reliably. If it is not 12 years old, you may have a little life left. If it is more than 12 years, it may be time to replace the system.
