Description

(54) СТАБИЛИЗИРОВАННБШ ИСТОЧНИК ПИТАНИЯ ПОСТОЯННОГО ТОКА(54) STABILIZED DC POWER SUPPLY

противоположный вывод которого соединен со вторым выводом светоизлучател  5, кроме того, средн   точка резистивного делител  7 соединена с первым выводом органа 2 защиты.the opposite terminal of which is connected to the second terminal of the light emitter 5, in addition, the middle point of the resistive divider 7 is connected to the first terminal of the protection organ 2.

Источник работает следующим образом . При включении источ«ика включаетс  дополнительный источник 6 питани . Через светоизлучатель 5 оптрона 3 протекает ток, в результате чего отпираетс  фотоприемник 4 и напр жение поступает на регул тор 1, а через него - на выход источника электропитани .The source works as follows. When the power source is turned on, an additional power supply 6 is turned on. A current flows through the light emitter 5 of the optocoupler 3, as a result of which the photodetector 4 is unlocked and the voltage goes to the regulator 1, and through it to the output of the power supply.

При возникновении аварийного режима орган 2 защиты включаетс , в результате чего резко снижаетс  ток через светоизлучатель 5, что, в свою очередь, приводит к запиранию фотоприемника 4, так как ток через фотоприемник становитс  ниже тока удержани . Дл  восстановлени  нормальной работы источника после устранени  при .чины возникновени  аварийного режима необходимо выключить, а затем снова включить источник электропитани .When an emergency mode occurs, the protection organ 2 is turned on, as a result of which the current through the light emitter 5 decreases sharply, which in turn causes the photodetector 4 to lock, as the current through the photodetector becomes lower than the holding current. In order to restore the source to normal operation after it has been removed, the emergency mode must be turned off and then the power source turned on again.
