What is emergency power?


As you know, due to the dependence of the function of electrical devices and appliances and vital needs on electricity, a device that can provide the required electricity immediately in case of a power outage and work temporarily until the city power outage is definitely not a problem during a power outage. It will not happen in different industries, companies and factories.

An emergency power system is your solution in the event of a power outage. The need for backup power or emergency power is greater in places such as hospitals and places that feed on dangerous electrical equipment, and this need is felt even in homes and complexes with elevators. In the following, we will examine the types of emergency power, how it works, and its differences and benefits.


Familiarity with emergency power types

You have probably heard about emergency power, but you are not familiar with its nature and how it works. An uninterruptible power supply is an independent power source that powers electrical systems in the event of a power outage.

An uninterruptible power supply can include batteries, UPS, solar panels or generators, which can be used to provide an uninterruptible or alternate power source depending on the requirements and application.

Concept of UPS (UPS)

UPS Makhef (Uninterruptible Power Supply) in Farsi is an uninterrupted power source, which means that the power required by the devices connected to it is supplied through the energy stored in the battery, which, in case of a power cut, without interruption It provides the necessary load power of the devices.

UPS works with a battery and if the city electricity is connected, it uses it to charge the battery, and if the city electricity is cut off, it takes it out of the circuit and puts the battery in the circuit.

Functions of the UPS device

The main task of the UPS is to create a direct reliable connection during severe power fluctuations and power outages so that the electronic device connected to it does not suffer from problems and breakdowns.

UPS uses two sources for its energy supply, the first source is city electricity, which are connected to each other with a plug, in this way, the required energy of the device is provided.

If the power goes out, the UPS comes into action and supplies the device with the energy it has stored in its batteries. The UPS battery is inactive under normal conditions, that is, the electrical energy of the electronic devices is supplied by the city electricity, and the UPS battery is also charged in the same way.


In short, generators are useful devices that produce electricity and prevent interruptions in daily activities or work flow interruptions. Generators are available in physical and electrical types for various applications. In the following sections, we will examine how the generator works, the main components of the generator, and how the generator works as a secondary power source in residential and industrial applications.

How the generator works

A generator is a device that converts mechanical energy from an external source into electrical energy for output. It is important to understand that generators do not actually produce electrical energy. Instead, it creates electricity as the output of the system by creating mechanical energy and creating motion and electric charge in the circuit coils.

This electric charge current is the electric current sent by the generator. The mechanism of the generator can be understood by understanding the operation of the water pump which causes the water to flow, but in fact it does not create water, only water flows.


What is an inverter and its advantages and disadvantages compared to a generator

In fact inverter or device converter which can convert low voltage electricity into high voltage electricity. The inverter can convert 12 volts to 230 volts through the car battery and it can be better than the generator because it does not make noise during operation.

Of course, the possibility of generating electricity with a generator is more common and can provide you with an output voltage of 120 or 240 volts.

When using an inverter and a car battery, you should pay attention to the storage capacity of the battery. A car battery can supply 12 volts of voltage with a current of 25 amps for 80 minutes because the capacity of a normal battery is 80 minutes. This indicates that the inverter is not suitable for long-term high voltage applications and the generator would be a better choice than the inverter.

Finally, use a clamp meter to test the battery, current and output voltage to determine the correct input voltage of your devices.

Important tips for choosing an emergency power system

In general, there are many important points for choosing an emergency power system that you should pay attention to. The most important points are mentioned below. You need to know how much voltage and power consumption you need for the devices. Collect the power required for the equipment that needs to be turned on during a power outage and provide the appropriate UPS, inverter or generator for your devices based on the amount received.

In general, you should use a more powerful power supply for high-power devices. In such cases, a UPS can be a much better option than a generator and can provide more voltage and current to electrical appliances.

If you want to use an uninterruptible power supply for sensitive equipment such as a television, you must make sure that the output voltage of the supply is controlled and constant so that the equipment does not burn out. For sensitive equipment, using a UPS that can maintain a constant output current is a better option.
