What is the voltage standard of intelligent toilet solenoid valve in the world?

Voltage (voltage), also known as potential difference or potential difference, is a physical quantity that measures the energy difference caused by different potentials of a unit charge in an electrostatic field. It's equal to the work done by A positive charge moving from point A to point B by an electric field force, and the direction of the voltage is defined as going from high to low. The international system of units of voltage is volt (V, referred to as volt), and the commonly used units are millivolt (mV), microvolt (μV), kilovolt (kV) and so on. The concept is similar to "water pressure" caused by high and low water levels. It should be pointed out that the term "voltage" is generally used only in circuits, while "potential difference" and "potential difference" are generally used in all electrical phenomena.

Intelligent toilet solenoid valve control coil, control coil working voltage dc and AC, to the international brand German Ward WODE solenoid valve as an example, commonly used voltage dc 24V,48V, ac 127V,220V,380V, etc..

But there are many kinds of voltage in the world, and the standard is not the same. Let's distinguish and introduce:

Voltage profiles by country in the world

100V: Japan, North Korea

110 ~ 130V: Taiwan, United States, Canada, Panama, Cuba, Lebanon, Mexico

220 ~ 230V: Britain, Germany, France, China, Singapore, Hong Kong (200V), Italy, Spain, Greece, Austria, Holland, The Philippines, Thailand, Norway, Singapore, India, New Zealand, Australia

Note 1: countries that use 220 ~ 230V voltage also use 110 ~ 130V voltage depending on regional needs, such as Sweden and Russia.

Most countries use 220 ~ 230V voltage for indoor electricity, because high voltage has the advantages of energy saving and high thermal efficiency. Recently, Japan's plan to raise the voltage has aroused wide discussion in the country.

Here are the voltages for each country:
