or even to control the abnormal state (over-current or anti-short circuit) protection circuit action. so that the control does not work. requirements of this clause is set at the access led control devices or capacitive capacitive load when the control unit should maintain a good working characteristics. for led control, [link widoczny dla zalogowanych] in addition to the overall style (controls and led makecan not be apart of one structure) and can clearly see the load capacitance does not have the characteristics, the other ofthe led control unit that, through this test. test circuit shown in figure 5.
it is noteworthy that the line-side electronic control devices harmonic current is generally relatively large, and the high harmonic current is not no work, but doing work of high harmonic currents in power factor lower than the fundamental time, so , [link widoczny dla zalogowanych] where the power meter should be used to measure the power of low power factor table, and the maximum operating frequency ofthe instrument should reach 1% of harmonic components in the frequency of that harmonic. so as to ensure the accuracy of measurement.
at the same time designers no longer have the headache for theimpedance matching; 2.3, digital optical transmitter can be modulated drive circuit. digital baseband signal as long as the line through a simple code,[link widoczny dla zalogowanych] you can directly drive optical transmitter. now, the price of fiber optic devices has dropped significantly compared with the previous, and future price increases as the cable and fiber optic devices further decline in prices, people will no longer select the first optical fiber, regardless of price.
