描述
/ Description
Instruments
The units are equipped with separate illuminated 3½ digit
13mm LCD volt- and amperemeters. In both cases it is
possible to independently switch between the value set,
the actual value or the OVP value.
Remote adjustment of the output voltage
The output voltage can be externally set by means of an
external voltage of 0...10V for U
0
...U
max.
The terminals for
the external programming are on the rear of the unit.
Remote adjustment of the output current
The output current can be externally set by means of an
external voltage of 0...10V for 0...10V for I
0
...I
max
. The termi-
nals for the external programming are on the rear of the unit.
IEEE bus
As an option, the units can be equipped with an IEEE bus
interface or an Ethernet interface. The connection terminals
are located on the rear of the unit. Further details about
measuring and control features of the IEEE or Ethernet
option are available in the option's user instruction manual.
High voltage output
The high voltage output is located on the rear of the unit.
Because of the wide output voltage range there are different
output configurations regardig the termination of polarisa -
tion. These are as follows:
Models 1.2kV to 12kV
The output is equipped with a high voltage connector Y-
series from LEMO. The polarity can be reversed internally
(only by EA specialists).
By default, the "–“ is internal connected to PE, so "+" is con -
nected with the center wire of the HV connector. The screen
is connected to PE. The center wire leads the high voltage,
the screen may not be used as a part of the load wire.
The screen may not be used as load connection. The
return line must be connected to the PE terminal. GND
is always connected to PE.

总线或以太网接口选项的测量
和控制特征，可参考用户说明书选项部分。
高压输出端
高压输出端位于产品后板。由于宽范围的输出电压，针对
终端极性不同会有不同的输出配置。具体如下：
1.2kV
至
12kV
型号
此类产品的输出端配有一由
LEMO
公司制造的
Y
型高压连
接器。可从内部反接其极性（ 仅
EA
公司专业人员方可执
行 ）。
默认状态下，
"–“
从内部连到
PE
，故
"+"
就连到
HV
连接器的
中性线。中性线输出高电压，屏蔽线不可用作负载线的一
部分。
屏 蔽 线 不 可 用 做 负 载 连 接 。 回 流 线 必 须 接 到

端 子
上。
GND
一直连到
