Why the charger power charger don't pull out exactly how much electricity consumption?
With the development of smartphones, mobile power consumption is more and more big, this also contributed to the smartphone is almost a day filling, even one day a few charge.
So, in order to easy to use, a lot of people will remain in the socket charger has been, but the power consumption is very terrorist.
If the country's 1 billion cell phone users in one 8 of the users, which will remain in the socket charger, usually it takes enough electricity to make 6000 sets of household air conditioning at the same time.
This time we can't help wondering, why power charger, how much electricity consumption, other electrical appliances will power?
Why do the charger power?
Most mobile phone chargers are belong to the switch power supply, the rectifier to dc 220 v first, and then by high frequency transformation, through the pulse transformer coupling, one-way output low voltage dc rectifier.
Even if there is no output current, high frequency conversion part is still at work, it takes part of the electricity.
The control circuit such as charger, the main is induced on the mobile phone is connected to the charger, the charger is not connected to a phone, control circuit is also at work.
Such as load component (again
Individual charger indicator lights)
, when the plug on the power supply is also at work, will also be part of the electricity consumption.
In short charger type of equipment on the plug in the power supply is bound to consume electricity.
The charger will be how much electricity consumption?
In fact, a single charger no-load power consumption is not big.
The communications industry standard yd - of the People's Republic of China
2009 the mobile communication terminal power adapter and charge/data interface technology requirements and test methods stated in rated output current of the power adapter should be in the range of 500 ma and 1500 ma, be determined by the manufacturer.
Under the power adapter no-load power consumption, power consumption is less than 150 milliwatts.
We use the normal charger will conform to the state's standards.
But as mentioned above, if the majority of users of the charger is left on the power supply condition, accumulate over a long period of power consumption or let a person very shocked.
Will other home appliance equipment power consumption?
We commonly used in the home charger is mobile phone, computer or other electronic device adapter, these is will have different levels of power consumption in idle.
And our home in other devices, such as television, refrigerator, air conditioner, etc. , under the state of standby power consumption.
In home appliance manufacturers will products before they go out through the corresponding standby power consumption test, general this time there will be those kinds of measuring equipment set up power meter on the production line.
By measuring results determine whether meet the national standards, can leave the factory.
In the test of the standby power consumption of household appliances, electronic zhiyuan PA300 series digital power meter adopts the design of the new architecture, are subject to a series of optimization in the aspect of low power consumption measurement, minimum measured current as low as 50 & mu;
A, can be measured as low as zero.
01 w power consumption, in line with international standards (
IEC62301, energy star, SPECpower)
In addition, PA300 series digital power meter high and 500 ks/s sampling rate and 300 KHZ bandwidth, can measure high frequency signal, meet new technology such as frequency home appliance, switch power supply product power consumption measurement.
Organization of data from the network.
