About this calculator
The no-break ideal power calculator is a useful tool for electrical construction professionals. It helps determine the necessary power for lighting systems or other electrical equipment, taking into account the load and loss of efficiency due to the use of no-breaks.
The formula used by the calculator is simple: load × 1.4. This means that the necessary power is equal to the load of the equipment or system, multiplied by 1.4. This multiplication is necessary because no-breaks have an efficiency of around 70-80%, meaning that a part of the consumed energy is converted into heat.
The no-break ideal power calculator is especially useful in electrical construction projects that involve the installation of lighting systems, air conditioning, elevators or other equipment that require a large amount of energy. In addition, it helps avoid overload problems and ensure a safe and efficient electrical installation.
Frequently asked questions
What is a no-break?
A no-break is an electrical device that maintains a constant voltage in a load, even during a power supply failure. It is used to protect sensitive equipment from damage caused by voltage fluctuations.
Why is it necessary to consider the efficiency loss of the no-break in the calculator?
The efficiency loss of the no-break is important to consider because it affects the necessary power for the system. If it is not considered, there may be an underdimensioning of the system, leading to overload problems and other safety issues.
When should I use the no-break ideal power calculator?
The calculator should be used in electrical construction projects that involve the installation of lighting systems, air conditioning, elevators or other equipment that require a large amount of energy.
What is load?
The load is the amount of energy required to operate an electrical equipment or system. It is measured in watts (W) or kilowatts (kW).
