What Does The 100v-240v on The Charger Mean?

2023-03-21 ZONSAN often concerned about the partners should have noticed that the charger information parameters are several important indicators, such as model, input voltage, output voltage, certification, etc., the input voltage labeled 100-240V such words, what are these?

The world's regional power grid



Input voltage actually refers to the working voltage of the charger, the charger is inserted into the socket connected to the utility for power supply, the world's residential electricity all use AC AC power, voltage ranging from 100V to 380V, single-phase residential electricity is generally in the 100 to 240V voltage range, according to the AC frequency division, a total of 50Hz, 60Hz two, chargers are basically compatible with the two frequencies. Through the above parameters quick check table grid can be seen, from the voltage, can be divided into two main voltage system 220V, 110V.

100V-240V working voltage



Currently on the market popular chargers, most of them support 100V-240V operating voltage, the internal circuitry is designed in accordance with the needs of a wide range of voltage, while compatible with 220V, 110V two voltage system, some design margin can even support 90V-264V operating range. This support 100V-240V working voltage charger can be used in China, in addition to cross-regional travel is also compatible with other areas of the power grid, whether for home use or travel to take away can be well adapted to the local power grid, to achieve global availability.

200V-240V working voltage



In contrast to the 100V-240V globally available voltage charger, another is the use of 200V-240V or 100V-120V input voltage charger, this charger working voltage range is relatively narrow, can only be used in some areas. For example, the black charger with 200-240V voltage in the picture, it can be used in China, the United Kingdom, France and other countries and regions with 220V system, but it may not work properly if brought to the United States for travel.

Why treat it differently



Since 100V-240V can be applied to the global grid, why not all chargers use a wide range of working voltage design?

In fact, both designs have their own advantages. 200V-240V or 100V-120V input voltage chargers can't be taken for global travel, but also because they don't need to take into account the wide voltage operating range, so the primary capacitors and transformers used inside these chargers can be properly adjusted, making it easier to achieve more charger power in the same volume housing, usually found in high-density High-powered small guns.



In addition, if you have panned Japanese appliances, they are usually designed for a single operating voltage of 100V-120V or 200-240V, corresponding to different voltages in different regions, to avoid cross-zone sales and protect the interests of different regional distributors.

ZONSAN summary

After reading the article, I believe we all have some understanding that there are different types of chargers working voltage, 100V-240V, 100-120V, 200-240V, etc.

100V-120V, 200-240V belongs to the design that can only work in a single grid system, generally used to enhance the higher power density of the product, the user only at home with words do not need to worry.

100V-240V wide range of voltage, covering 110V, 220V two mainstream grid system, cross-regional travel can also be used to carry, is also the current market mainstream hot chargers are used to work voltage, in addition to the need to pay attention to the local plug specifications adopted by what standard, bring the travel conversion plug to be prepared.
