An Uninterruptible Power Supply is a device that sits between a power supply (e.g. a wall outlet) and a device (e.g. a computer) to prevent undesired features of the power source (outages, sags, surges, bad harmonics, etc.) from the supply from adversely affecting the performance of the device.
Research shows that power outages, voltage drops and short and sudden changes in the city network damage your computer system and computer controlled devices.
Because of the critical loads in your company, you need to isolate your work flow from such problems.
Uninterruptible power supplies are the devices that provide the best protection. (UPS) No matter how uninterrupted your electricity network is, the possibility of a surprise interruption is very high in case of any natural disaster (storm, rain).
Even a fuse blown in the distribution board of your building will appear as a problem that will hinder your work.
On-Line: It regulates the voltage and frequency by always staying on and recharges the batteries when there is electricity and generates electricity from the batteries when it is cut.
Line interactive: It is not active when there is electricity, only the regulator part makes simple voltage regulation gradually and the frequency is not regulated. When the electricity is cut off, the inverter section is activated.
Off-Line: It is not active when there is electricity and does not regulate the voltage when there is electricity. It is activated if the network falls below or exceeds the specified limits.
UPS devices must be able to supply the total critical load power in your system without any problem.
In this case, the power of your UPS device should be at least the sum of your critical loads.
You can find the total power you need by the method of collecting the power labels on the back of your devices.
It will be good for performance to choose the UPS that is at the higher level of the value you obtain.
UPS devices provide its energy from the battery group when the power is cut off.
In this case, the energy we have is equal to the total energy of the batteries.
When the electricity is cut off, this energy starts to be used up slowly and ends completely after a certain period of time.
In this case, the UPS device stops and the critical load remains de-energized.
This period is all about the way you work:
Short times (5-20 minutes) If you only want your information and computer system to be protected in a surprise interruption, long working times (1-3 hours) If your business requires uninterrupted service, our company offers different battery-term packages for each UPS model.

Static Transfer Switches are devices that provide uninterrupted transition from the main energy source to the backup energy source as much as possible.
In these devices, the quality of the energy source is defined by the user.
If parameters such as voltage or frequency are out of the defined tolerances, the device transfers the critical load to the backup energy source.
It tries not to create interruptions as much as possible during the transfer, but because the voltage and frequency change of the sources are not managed by the device, very short interruptions may occur under some conditions.
In applications with two energy sources, if there is a critical load, a switch mechanism is needed to transfer the load from one source to another; can not detect in a while..
The STS device measures the sources continuously, detects any interruptions within 2 milliseconds and performs the transfer process automatically and there is no interruption at the time of transfer.
It can be used to switch from one power line to another in places where there are two energy networks, in transitions between generator and network, and to switch from one UPS to another where two UPSs are used.
No, the functions of the two devices are different. UPS creates AC energy from the battery when power is cut. STS, on the other hand, allows the desired transition between two existing power lines at the same time.
Yes, there are many applications using STS at UPS outputs. In places where more than one UPS is used, STS can be used to switch from one UPS to another.
Yes, the maximum output current of the device varies according to your load. For this reason, before purchasing the STS device, your load should be determined and an STS device should be provided according to this value. The power of STS devices is referred to in terms of the current drawn (amperes), not in kVA. In other words, if your current need is 80 amperes, an STS device with a capacity of 100 amperes will meet your needs.
STS devices meet currents up to 1000%, ie 10 times the normal current, in very short periods of time and are produced in such a way that the device itself does not cause any interruption up to this current.
Yes, STS devices can be controlled and monitored by RS232 serial communication and TCP / IP protocol. Special software provided with the device is used for this process.
No, the most important feature of the STS device is that only the energy source used at that time is loaded when the output is short-circuited, and after a very short time, the device cuts the output voltage and prevents the other source from being loaded.
Three-phase conventional submersible or surface pumps with powers of 5.5kw (7.5 horsepower) and above, normally powered by mains electricity or generator, can now be operated directly from solar panels during the daytime, thanks to today's technology, in places where there is no electricity grid.
This system; It consists of solar panels, Mppt power conditioner, motor driver, solar panels mounting constructions and, where necessary, water tank.
Thanks to the Mppt power conditioner, the highest instantaneous power received from the solar panels during the daytime is transmitted to the motor driver. The driver changes the speed and / or torque of the pump shaft according to the transmitted instantaneous power, and offers low flow water in the morning and evening hours and high flow in the noon hours. Water can be used immediately, or it can be collected in a suitable volume tank and used for evening or night irrigation.
The equipment and cost to be used in the system arise with the technical project to be made on the following data:
Thanks to these systems, the energy generated during the day in solar panels is pushed to the electricity grid through the grid inverters, and the electricity subscriber's electricity expenses in a certain period of time are reduced, reset or profit (electricity sale) situations are provided.
On-Grid systems; It can be used wherever mains electricity and sufficient solar panel mounting area is available. Its main equipment is solar panels and grid inverters. Technically they can be installed at any power scale without power limit, so these systems have a wide range of uses, from the smallest household application to the largest solar power plant (GES) application. Agricultural irrigation, agriculture and livestock sectors are also prominent areas of use.
In accordance with the renewable energy law (YEK) regulation, which entered into force on October 2, 2013 in Turkey, every electricity subscriber has the right to power the energy produced from renewable energy sources up to the limit of 1MW installed power, without requiring a generation license, on the basis of meeting their own energy consumption. In this context, the subscriber is only subject to the technical procedures of the public or private electricity distribution company to which it is affiliated. The energy consumed and produced by the subscriber will be offset from each other at the end of the billing period. In the event of a possible energy production surplus, the electricity distribution company will purchase this energy surplus if the subscriber is able to issue an invoice.
A grid-connected PV-system to be installed in order to meet the electricity consumption of a subscriber who has a constant electricity consumption during the billing periods of the year and not to create energy surplus will be projected on the basis of summer months. In this case, it is expected that 65 - 75% of the total annual electricity expenses of the subscriber will be saved in sunbathing conditions in Turkey, depending on the location.
The equipment to be used in the system and the preliminary cost before the discovery arises with the technical project to be made on the following data:
