obvious feature of these controls is that as long as the output of the led forward voltage loads in series additive control voltage is not higher than the maximum output voltage value, more or less strings string a few of several led led, the control device fundamental change in the output current does not exceed 30%, and also guarantee direct limit with no additional impedance led work. [link widoczny dla zalogowanych] control output current control devices of the most distinctive features is that when the supply current changes in the lusm10% range, the control device does not require additional current limiting impedance loads directly to ensure that the appropriate led to work.
equation (1): p-power supply active power ballast and lamp systems. s-power supply ballast and lamp systems, as in power. u-voltage i - supply current work as electronic control devices,in connection with the power supply wire, [link widoczny dla zalogowanych] both fundamental current and harmonic currents of the existence of another control device to the power leakage of high frequency conducted interference feedback current exists (emi), but the definition of the type look.
designers do not consider the possible environmental noise coupling came; 2.2, fiber optic communication links provide electrical isolation between the two sides, [link widoczny dla zalogowanych] eliminating long-distance potential between devices due to the different problems caused.
