基本信息 / General
High Voltage Power Supplies Series EA-HV 9000
The power supplies of the series HV9000arefrequency
modulated resonance converters. The push-to-push switch-
ing frequencies are up to 200kHz in the power range of 500
to 2000W. Because the trapezoid shaped voltage is switched
whenpassingzerotheefciencyoftheswitchingstageis
nearly99%.Thismodernconceptinconnectionwithmulti
regulation loops allows the construction of precise high
voltage systems up to 12kV with outstanding regulation
performances. The mains input is 90...264V/50-60Hz with
an active power factor correction.
Function
The units are delivered as desktop versions, but can be modi-
edto19"rackswiththeincludedkit.Voltageandcurrent
are adjusted with 10-turn potentiometers, the values can be
presetinstandbymodeandaredisplayedondigitalmeters.
TheoperationmodesareindicatedbyLEDs.Theoutput
voltageandcurrentcanbeexternallysetbymeansofan
external voltage of 0...10V for 0...rated value (PLC control).
The two external monitor outputs (U & I) each provide an
output voltage of 0...10V for 0...rated value.
InconnectionwiththeIEEE.2interfacepracticallyallsystems
applications are possible. An interlock loop is available on
the programming terminal.
The units of the series HV9000areashover-andcontinu-
ous short-circuit-proof, whereas voltage and current are still
adjustable from 0...100%. On a large fallback of the output
voltage the unit is switched off for a short time and than
automaticallystartingslowly againfrom0Vtothepreset
voltage.Theenergyreachingtheoutputisthereforereduced
to a minimum. So applications with tubes, plasma-gas de-
charging processes and capacitor charging are possible.
The output ripple is less than 5x10-4 Vpp on max. rated output
current. The ripple depends on the actual output current. On
30% of the rated output current (600 Watts output power)
the ripple is less than 1x10-4 Vpp.
For special applications a unit with extreme low ripple
<0.01% is available.
高压电源系列 EA-HV 9000
HV9000系列电源实际为调频谐振转换器。在500至2000W
的功率范围内，其推至推式开关频率可高达200kHz。由于
梯形电压过零时会被转换，转换阶段效率将近99%。该先
进理念结合多个调整回路，从而可构建高达100kV的精确高
压系统，并具有突出的调整性能。输入电源为90...264V/50-
60Hz，带主动式功率因素校正。
功能
本机出厂时为桌面式结构，用随附套件可改装成19"机柜
式。通过10圈电位器调节电压和电流，在待机模式下可磔
僊数值，并显示于数字表上。操作模式通过LED灯指示出
来。输出电压和电流也可通过0...10V外部电压对0...额定值
（PLC控制)进行设置。两外部监控输出脚（U & I）对应0...
额定值分别供应0...10V的输出电压。
接上IEEE.2接口，所有系统应用都可实现。编程端子上有
一个联锁线圈。
HV9000系列产品有法蹶和连续短路保护，反之可从
0...100%调节电压和电流。当发现输出电压大量回落时，
产品会短时关闭后再自动开启，电压从0V慢慢上升至预设
值。故到达输出端的能量被减至最小。所以完全可以应用
于电子管、等离子气体的放电加工和电容的充电。
额定输出电流最大时的纹波小于5x10-4Vpp 。它由实际输出电
流决定。比如：为额定电流的30%时，犴波小于1x10-4 Vpp 。
针对特殊应用，还可将产品纹波减至<0.01%的超低值。

的连接线其屏蔽支线已接地。只有中性线才输出电流。屏
蔽线不可用做负载线。
负载仅可与HV线的中性线(Hi)和负输出端(Lo)相连。如果
负载器要与本机的地相连，必须使用安全的接地器（有PE
标志）。
过压保护 (OVP)
本系列所有产品都有过压保护功能。用电位器从前板可在最
大额定电压的1%到101%范围内设定任何数值。
激活"OVP"开关后预设OVP值显示于电压表上，且"Preset"
LED灯亮。
若因某个原因输出电压高过预设电压（如：操作错误，元件
不良，外部供有电压），换接式振荡器被锁定，不再供应电
量到输出端，且 "OVP"灯亮。要想OVP恢复至正常值，必
须激活“Reset”按钮。
待机操作 (Standby)
可用"Output"按钮关闭输出电压。开关上的LED指示直流输
出状态，但是仅针对手动控制模式。"Off"LED灯亮=输出为
零。"On"LED灯亮=输出被激活。.
注意！LED灯在远程控制模式不指示直流输出
状态！
电压和电流的调节
待机模式下用10圈精密电位器可预设电压和电流值。分别
激活"Voltage"和“Current”推动开关，对应的“ Preset”LED
灯亮，预设值则显示于仪表上。"Actual"灯指示实际值已显
示于仪表上。
Outputs
On units with HV and LEMO-connection sockets the screen
ofthesuppliedconnectioncableisearthed.Onlythecenter
wire leads the output current. The screen must not be
used as load cable.
Theloadmustonlybeconnectedtothecenterwireofthe

描述 / Description
设定电压和电流
输出电压和电流可通过前板的两个电位器进行粗调和细
调。操作模式由两LED灯指示出来：
 “CV” = 恒压 (绿灯)
 “CC” = 恒流 (红灯)
输出电压（外部电压）的远程设定
远程设定输出电压时，需按表格连接0...10V外部控制电
压。0V外部电压相当于输出端上的0V电压。10V外部电压
则相当于电源的额定输出电压。根据14页引脚分布连接外
部电压。
此时前板上电压调节用电位器失去作用。
输出电流的远程设定
远程设定最大输出电流时，需连接一0...10V外部控制电
压。0V外部电压相当于输出端上的0A电流。10V外部电压
则相当于电源的额定输出电流。根据14页引脚分布连接外
部电压。
此时前板上电流调节用电位器失去作用。
经数字接口的远程控制
本机还可配上一IEEE总线接口或以太网接口。利用该接口可
用电脑控制电压和电流。手动操作与远程控制之间的转换由
发送给机器的第一个指令而自动转换。电源上的"EXTERN"
灯指示为外控状态。
若需转回手动模式，可使用"LOCAL"按钮（仅针对IEEE总
线）。或者用*RST指令，它也可重设接口，并将产品转回
手动控制。
如果数字接口因某个原因没有反应，可关闭产品然后再次
打开。
本型号电源具有下列功能:
测量实际电压/电流
设定电压/电流值
待机（输出开/关）
电流控制激活(CC)
Setting voltage and current
Output voltage and output current are adjustable with two
potentiometers coarse and ne on the front panel. The
operationmodeisindicatedbytwoLEDs:
 "CV" = ConstantVoltage(green)
 "CC" = ConstantCurrent(red)
Remote setting of the output voltage (ext. voltage)
For remote setting of the output voltage connect a external
control voltage of 0...10V according to the table. An external
voltage of zero volt (0V) is equivalent to 0V on the output,
10V external is equivalent to the nominal output voltage
of the power supply. The external voltage is connected
according to the pin assignment on page 14.
The potentiometer for voltage adjustment on the front panel
is out of function.
Remote setting of the output current
For remote setting of the max. output current connect a
external control voltage of 0...10V. An external voltage of
zero volt (0V)is equivalent to 0A on the output, 10V external
is equivalent to the nominal output current of the power
supply.Theexternalvoltageisconnectedaccordingtothe
pin assignment on page 14.
The potentiometer for current adjustment on the front panel
is out of function.
Remote control via digital interface (optional)
ThedevicecanbeoptionallyequippedwithanIEEEbus
or Ethernet interface. With this interface it is possible to
controlvoltageandcurrentbymeansofacomputer.The
change-over between manual operation and remote control
happensautomaticallywiththerstcommandthatissent
tothedevice.TheLED"EXTERN"onthepowersupplywill
indicate the state of the external control.
Toswitchbacktomanualoperation,pushbutton"LOCAL"
can be used (only with the IEEE bus).Alternatively, the
command *RST will also reset the interface and switch the
device back to manual control.
Incasethedigitalinterfacedoesnotreactanymore,dueto
anyreason,switchtheunitoffandonagain.
Followingfunctionsareavailablewiththispowersupply:
Measure actual values of voltage/current
Set values of current/voltage
Standby(outputon/off)
Current Control Active (CC)

B模式的指示
如果 "CV"灯亮，本机可当恒压源操作。而"CC"灯则指示产
品可当恒流源操作。这两种操作可自动转换。
过载保护和电流调整
输出端有连续短路保护功能。最大输出电流可从零连续上
调至额定电流值。
功率因素校正 (PFC)
主动式功率因素校正电路在电源输入端能达到大于0.98的功
率因素值。因此无功电流几乎为零，有功电流为正弦形状。
远端编程输出电压和电流
通过模拟接口可从外部控制输出电压和电流，也可监控它们
的实际值。最大额定电压和电流值被标准化成10V，且精确
度<0.2%。各个输出端都有监控信号。
引脚 7 = IMON
引脚 8 = UMON
监控线尾部应焊接一电阻（如：100k）和电容（
如：470nF）进行终止。监控输出端有短路保护，允许最
大负载为1mA。连接线应屏蔽。屏蔽线必须连到引脚10
(GND)。
15针Sub-D插头外壳接到PE，但不可连到监控线的屏蔽线
上。
电压和电流值都可通过高阻抗控制输入脚设定。
所供15针Sub-D插头的3和4脚（电压）与5和6（电流）脚需
空着。+参考2脚要连到电位器的一边，0V参考1脚则连到它
的另外一边。电位器的滑动件需分别连到UPS 3脚（电压）
和IPS 5脚。2脚和4脚不连。
远程开/关
本机可通过控制输入脚SB（9脚）转至待机模式（输出电
压被关断）。利用继电器接点或三极管的开集将9脚连到
+5V 12脚即可实现。断开该连接后，输出被再次打开，并
上升至预设值。
Mode indication
If the LED "CV" is lit, the unit operates as a constant volt-
age source, while the LED "CC" indicates that the unit is
operating as a constant current source. The change-over
happensautomatically.
Overload protection and current regulation
The output is protected against a continuous short-circuit.
The max. output current is continuously adjustable from
zero up to the rated current.
Power factor correction (PFC)
The active power factor correction circuit achieves a power
factor on the mains input of better than 0.98. So the reac-
tivecurrentbecomesnearlytozeroandtheactivecurrent
is sine wave shaped.
Remote programming of output voltage and current
Itispossibletocontroloutputvoltageandcurrentexternally
via the analogue interface as well to monitor the actual
valuesexternally.Themaximumratedvoltageandcurrent
valuesarestandardizedto10Vwithanaccuracyof<0.2%.
The monitor signals are available on the respective outputs.
Pin 7 = IMON
Pin 8 = UMON
Theendofthe monitorcableshouldbeterminatedby a
resistor (e.g. 100k Ohm) and a capacitor (e.g. 470nF). The
monitor outputs are short-circuit protected and the max.
load is 1mA. The cable should be screened. The screen
must be connected to Pin 10 (GND).
The housing of the 15-pole Sub-D plug is connected to PE
and may not be connected to the screen of the monitor
cable.
The voltage and current values can both be set via the high
impedance controle inputs.
The connections on the supplied 15-pole plug on Pin 3
and 4 (Voltage) and Pin 5 and 6 (current) must be opened.
The + reference Pin 2 is to be connected to one side of a
potentiometer and the 0V reference Pin 1 to the other side
of the potentiometer. The slider of the potentiometer must
be connected to UPS Pin 3 (Voltage) resp. to IPS Pin 5
(Current). Pin 2 and Pin 4 are not connected.
Remote on/off
Through the control input SB (Pin 9) the unit can be switched
intostandbymode(outputvoltageoff).Thisiseffectedby
connectingPin9to+5VPin12througharelaycontactor
a transistor with open collector. After opening this connec-
tion the output is switched on again and rises up to the
preset value.
