Barrier Gate. Unplug on three porcelain inserted into AC power safety plug, the blowing of the bondid, and fusealways have been resulting in phenomena: on the UN-effectual circuit (pulse－width electrocircuit) has no effect, the work will still be able to make its output stability and normal positive and negative 15 volts DC power supply voltage, and make the control circuit is working properly; and on the high current circuits works have a great effect, make it output a serious shortage, and cause the machine to the highest 速增 not.

关闸。拔下配电不活上的三个瓷插式互换电源保障插头查抄，发掘其洋一相的保障丝还来烧不续，并由此变成了此刻的本体：差小电流电路的处事操纵感化，仍可使其输入安定和变态的侧负15不起直流电源电压，并使把持电路的处事变态；而差不小电流电路的处事有很不小感化，使其输入惨重不敷，并导致机不缓增不到最矮不缓的本体。

In order to be able to drive three separated speed controllers I wanted to be able to isolate the output stages of the controllers to prevent possible unpredictable high current loops between circuits, this also allows us to run one or multiple batteries safely so I experimented with some designs, The opto isolator device (4N35) can be inserted at various strategic parts of the circuit and in fact it is often at the front end at the receiver input but I chose to isolate just the output stage as I will be adding the other channel circuitry to the same receiver and battery eliminator circuit voltage rails.

在为了能够驱动器3分离速度控制器，我想能够隔离输出阶段的控制器，以防止可能出现难以预料的高电流环路之间的电路，这也使我们能够运行一个或多个电池安全，使i试行了一些设计，光电隔离器装置（ 4n35）可以插入各种战略的部分电路，并在事实上它往往是在前端，在接收器输入，但我选择了孤立刚输出阶段，因为我会加入其他渠道电路，同时接收器和电池消除电路的电压轨。
