Some time ago, when I was talking to one of our acquaintances in the installation of a cooler, I realized how important it was to buy the best air conditioner. You probably didn’t know, like me, that most of the serious damages that damage the range and the compressor of the air conditioner have nothing to do with the air conditioner itself, and most of them were the result of electricity fluctuations, and once a few tens of millions of air conditioners were destroyed. Here are some examples of suitable electrical shields for air conditioning.
Model S7000
The S7000 is one of the few guards that is really designed for the air conditioner, not just with the high amp. If I want to tell you my opinion about this model very brief, I should note that the most important thing is the good balance between design, performance accuracy and safety.
The small dimensions of this device allows it to be installed even in the limited spaces behind the window or next to the split. The body is of the normal quality, but its design is in a way that performs stable against long -term heat. This is important in environments with extreme heat, as some protectors become unstable with rising temperatures.
LED lights on the device show three situations very simple: normal conditions, power fluctuations, and delay in restarting. In places where there is a high electricity fluctuation, these three cane lights will be identified to detect the status of the device without the need for the tool.
The most important feature of the S7000 is what should be: accurate behavior in the voltage range. The voltage below 1 and above 2 is cut off and does not allow electricity to pass by returning to the sustainable situation. Its delay is exactly four minutes, designed according to the safety principles for gas coolers.
You might think that it is a disadvantage, but in fact this feature is in your favor. Because indirectly causes it to connect only to the air conditioner. This may seem small, but it is very effective in protecting the peak time consumption.
Benefits | Disadvantages |
· Compact and appropriate design of the rear of the cooler · Standard 2 -minute delay for compressor | · No ground · Limited power than some similar models |

Part Electric Voltage Protector Model 689 Washing Cooler Model
First, we go to the most important feature of this model, the maximum tolerable voltage of up to 5V. Contrary to public notion, this number is not merely a technical data, but rather a proper understanding of the reality of the Iranian urban electricity network. In many areas, voltage fluctuations remain at the same threshold during the peak hours or when suddenly changed. The guards that can respond properly in this voltage range will neither cut or late, exactly what the air conditioner needs.
Parthian 689 has no cable and is connected directly to the socket. This may seem restrictive at first, but it is an advantage for a gas cooler that should not be connected to electricity at all. Keep in mind that direct protectors have a safer performance due to better contact and more stable connection and are more resistant to internal heat.
Another functional point is moisture -resistant plastic body. In environments such as balconies, kitchens, or areas with humid climate, air humidity can affect protective performance in the long run. But the design of this model is such that in such circumstances, it does not develop early burnout or dysfunction. In terms of support, the number of 1 amp is enough for coolers up to 6,000 as well as most washing models.
Overall we have to say that this bodyguard is reliable, despite its simplicity Of course, provided it is used in the right place. If you are planning to use this protector in a constant voltage fluctuation, it may be best to go for more detailed delayed timer models.
Benefits | Disadvantages |
· High voltage resistance (up to 255 volts) · Careful performance in power fluctuations | · LED LED marker for power status · No cable and sword |

Model Voltage Protective FR140; The best electrical shield of gas cooler in slow fluctuations
Voltage fluctuations are not always sudden or severe. We often face slow and chronic fluctuations; A process that does not cause any problems, but in silence, the range of the device is worn out. For such situations, protectors such as the FR140 are more functional and controlled against power fluctuations. This protector with a supportive power of 4V and 2 amp input current covers the coolers up to 6,000. So its application range is wide.
The FR140 has a compact design at first glance and is comfortable even in closed spaces behind the window or next to the inner cooler unit. Because without a cable and with a single outlet, it focuses on a device. On the other hand, as the body is resistant to heat and continuous use, it has been working for you for many years.
But the most important thing about this model is the accuracy of the voltage disconnection. The cutting range of this device is defined between 1 and 2V for voltage drop and 1 to 2 volts for high voltage. This range is technically precisely at a time where the voltage can be destructive to the board, but has not yet made the device shut down. The protector must cut power before the damage is caused, and FR140 does so without unnecessary delay.
Benefits | Disadvantages |
· High support power up to 4000 watts · LED markers for power status | · The body of the body is of medium quality |

Kaveh Model Cooler Voltage Protector KAP2140E
If we want to describe the KAP2140E in one sentence, we have to say a precise, intelligent delay and efficient design for coolers of 1 to 2,000 and even low -consumption models.
So far, we have found that the most important factor in choosing a protective air conditioner is the accuracy of the recognition of the fluctuation and the appropriate timing of the current. In practice, many protectors are either over -sensitive and cut off electricity for no reason, or over tolerance and do laterally. But this model with a defined voltage of between 1 and 2 volts is exactly at a point where neither cuts early nor late.
One of the positive features of this shield is the shorter delay time than industrial models (1 to 2 seconds). At first glance, you may feel less than standard, but in many new generation coolers that have a soft startup system or are used in areas with less swing, this shorter delay helps you don’t have to wait a few minutes for the return.
Benefits | Disadvantages |
· High power support · Have LED marker | A relatively short delay may not be fully protected for compressor of some coolers. |

Model Cement Protector SM-140AW
One thing that makes this model one of the best types of air conditioner protective brand is its relay performance. Unlike simpler protectives that are less accurate in disconnecting and connecting the current, this model with the relay controls the voltage better and at a faster speed. If the input voltage exits from 1 to 2 volts, it operates without irrational delay and does not connect the device until the conditions return to the safe state.
The 5 to 5 -minute delay in this model shows that the main focus is on protecting the compressor and the starter cooler circuit. This delay will help not put pressure on the moment at the moment of reconnection. This is important when the electricity is cut off several times; What we are seeing a lot these days.
The SM-140AW protective design is compact and hand-made. The direct connection without a cable makes it easy to install and fit in the back of the cooler. Entitlestated socket is also a key point; Because many air conditioners need to be better protected, and unfortunately this feature has been overlooked in many market protectors.
Benefits | Disadvantages |
· Professional and accurate relay performance · Have an ground -based socket | · Relatively long delay (1 to 2 minutes) |
