Q:Driving recorder dedicated power box for what use
3) to stop the process has been video, the need to split from the car line out of the conversion, the installation of a called "power through" adapter, the battery voltage can be automatically stopped when the recorder power supply (to prevent the battery voltage is too low Do not burn fire)
Q:S-350-12 monitoring dedicated switching power supply 12V29A transformer connection
12V switching power supply connected to the positive and negative, then the power will not burn, and most of the output is not, if it is a new power supply, then you can change one. The next time to pick up the first time with a multimeter to measure whether there is a short circuit, the best one of a power, on a power out of an image, no image and then check.
Q:What is the frequency of industrial electricity in the Philippines?
Frequency, is the unit time to complete the number of cyclical changes, is to describe the amount of periodic movement frequency, commonly used symbols f or u said, in units of seconds. In order to commemorate the German physicist Hertz's contribution, people put the frequency of the unit named Hertz, referred to as "He". Each object has an amplitude independent of its own nature, called the natural frequency. The concept of frequency is not only used in mechanics, acoustics, but also in electromagnetics and radio technology.
Q:What is the application of IF power supply in the industrial field?
1, smelting furnace metal smelting: This is one of the most widely used aspects of the development of China's thyristor power, began in the smelting, melting all kinds of carbon steel, alloy steel, alloy cast iron, copper and aluminum can also be, and Used to extract high purity zinc and other non-ferrous metals. Smelting load is the worst load of medium frequency power supply, yin anti-change is large, the load is unstable, but the intermediate frequency power supply can be very ideal to complete this task, the most prominent advantage is to save energy, every smelting IT steel power consumption around 500KW.h. Also easy to start, smooth steel, eddy water mixing small, good quality smelting.
Q:Site with industrial power 380V / 50hz, electrical equipment is 110v / 60hz. Is there a solution?
Voltage problem, 380V three-phase power, 110V should be single-phase power,
Q:What is the difference between computer power and industrial switching power supply?
From the power of the property terms, there is no difference. But from the functional point of view. Computer power can belong to industrial power. A wider range of industrial power supplies, the use of more power for industrial power. Generally believed that the power supply for industrial equipment, can be called industrial power. Also refers to those who are more powerful, more power supply.
Q:Dell 9020MT business computer can only use 290W dedicated power?
Yes. Dell 9020MT i7 version of the power supply is rated at 200W. 290w on the super. The rated power is the power at which the appliance is operating normally. Its value is the rated voltage of the appliance multiplied by the rated current. If the actual power of the appliance is greater than the rated power, the appliance may be damaged.
Q:Industrial electricity in the DPS.UPS, etc. are temporary power to Caesar ah
Can be used as a delay power supply, but the power supply time is limited, according to the battery configuration,
Q:Is the industrial atomizer good with a switching power supply or a toroidal transformer?
Not need long-term online work of industrial instruments, naturally use the switching power supply is better.
Q:What is the allowable fluctuation range of the industrial standard power supply 380v power supply voltage?
With other levels of power supply voltage fluctuations are as follows: 35kV and above supply voltage positive and negative deviation of the absolute value does not exceed the nominal system voltage l0%. Note: If the upper and lower deviation of the electrical voltage (both positive or negative), according to the larger deviation of the absolute value as a basis for measurement.
