Although some users
are nervous about operating power supplies in series,
it is common practice in the industry.
The benefit is that voltages greater than 60V can be obtained using off-the-shelf
products.
虽然某些用户对电源的串联作业存在忧虑，这在职业的运用中是一种普遍现象。其长处在于，制品电源选用串联方法可获得超越 60V 的电压。
It is possible to
connect several power supplies in series, but please read the precautionary
notes below:
能够将多台电源进行串联，但请事前仔细阅读以下阐明：
·
Connect back-biased
diodes across the power supply terminals as shown below.
·
如下图所示，在电源输出端子之间衔接反向偏置二极管。
Output 输出
Power
Supply 1 电源 1
Power
Supply 2 电源 2
Load 负载
Rate these diodes at the same output current as the power
supplies.
外加维护二极管的额外电流不得小于电源的额外输出电流。
In the event both power supplies do not turn on at the
same time, or if the load becomes a short circuit, then the diodes will protect
the power supplies from any applied reverse voltage.
当两台电源不是一起发动或许负载产生短路时，二极管能够维护电源免受外部任何施加的反向电压的影响。
·
Do not
exceed the output to ground/chassis voltage rating. Inside most power supplies are noise filter
capacitors connected from the output to ground.
It is possible to exceed the operating voltage of those capacitors,
particularly when configuring several units in series.
·
请不要超出输出到地/外壳的电压答应值。大部分电源内部都具有从输出衔接至接地端的噪声滤波电容器。尤其是当多台电源串联运行时，这些%&&&&&%器上的作业电压或许会超出答应值。
·
Avoid
using “fold-back style” current limited power supplies as these may lock up the
power supply during initial switch on.
·
防止运用过流维护模式为“关断式”的电源，由于或许会在初度翻开时电源被确定。
