Various options

Models from 1kW output power are equipped with a ?exible,
auto-ranging output stage. It provides a higher output voltage at lower output current or a higher output current at lower output voltage, always limited the max. nominal output power.
Therefore, a wide range of applications can already be covered by the use of just one single unit. The power set value is adjustable on these models from 0..100%, either manually or in remote control. Units with 1.5kW or higher are derated,i.e. reduced in their max. power at low input voltages.
Input
All units are provided with an active Power Factor Correctioncircuit and models up to 1.5kW are suitable for a worldwideusage on a mains supply from 90V up to 264V AC.
DC output
Output voltages between 0...32V and 0...720V, outputcurrents between 0...4A and 0...120A and output powersbetween 640W and 0...3000W are available.
The output terminal is located on the rear panel.
For applications where a fast variation of voltage from a highto a low value is required, models from 1kW and up to max.
400V can be equipped with a two-quadrants power-sinkmodule (active load).
The fast voltage variation is achieved by the capability of thispower-sink module to faster discharge the internal flter capacitors, as well as flter capacitors of the equipment connected.
Overvoltage protection (OVP)
Intended to protect connected loads, it is possible to defnean overvoltage protection limit (OVP).
If the output voltage exceeds the defned limit, the output isshut-off and an acoustic warning signal will be given by theunit and also a status message signal, in the display and viathe analogue interface, is available.
Alarm management
For monitoring the correct output voltage and output current,lower and upper limits can be defned.
If the deviation exceeds the adjusted limits, three possibilitiesare available as to how the appliance should react.
- Signals are displayed only, even if the fault is still active,without affecting to the output.
- Warnings remain active and must be acknowledged afterthe fault is removed.
- Alarms will shut off the output instantly in case the deviationexceeds the adjusted limits.
Alarms and Warnings can be signalled audibly.
Remote sense
The standard sense input can be connected directly to theload in order to compensate voltage drops along the powerleads. If the sense input is connected to the load, the powersupply will be adjusting the output voltage automatically toensure the accurate required voltage is available at the load.
Display and controls
Set values and actual values of output voltage, outputcurrent and output power are clearly represented on thegraphic display. The operating state of the device, the menuguidance and the current assignment of the pushbuttons arealso shown on the display. So the user is able to operatethe unit intuitively.

功率
1kW 以上型号输出功率可灵活调整。可在低电流时输出更高的电压，或在低电压时输出更大的电流，都由zui大额定输出功率来限制。 因此一台该产品能涵盖广范围的应用领域。设定功率可从0..100%之间可调，或手动调节或远程控制。 1.5kW型号产品有功率降额功能，即： 在较低输入电压时减少zui大输出功率。

输入
本系列所有型号都采用主动式功率因数校正线路， 1.5kW以下产品在为 90V 至 264V AC 输入电压下都可使用。

直流输出
本系列有多款不同型号，可选择0...32V和0...720V输出电压， 0...4A和0...120A输出电流， 640W和0...3000W输出功率的类型。
输出端位于产品后板。
针对电压由高至低快速跃变的应用， 1kW以上且电压在400V以下的型号，可配上两象限功率降额模块（有源负载）完成该操作。
通过功率降额模块对电源内部滤波电容和连接负载的输入滤波电容快速放电， 实现电压的快速变化。

过压保护 (OVP)
为保护连接负载，可设定一过压保护极限值 (OVP)。
若输出电压超过调节极限值， 输出被关断， 显示器和模拟接口发出一声频报警信号。

报警管理系统
为监控正确的输出电压和电流，可定义上、下限。
若偏差超过该调节极限，应用设备会出现下列三种可能性反应：
- 只显示信号；即使错误仍存在，也不影响输出。
- 警告一直持续， 消除错误后必须确认警告信息。
- 报警会暂时关断输出。
报警和警告发出声音信号。

远程感测端
远程感测输入端可直接连到负载设备，以补偿连线上的压降。 如果输入端已接上负载，本电源会自动调整输出电压，以确保负载获得准确所需的电压值。

显示和控制键
输出电压、 电流和功率的设定值、实际值都显示于图形显示器上， 还包括产品的运作状态， 菜单指引和按钮当前功能，故用户能直观地操作本产品。EA-PSI 8000 2U 640W - 3000W

显示器和控制面板
输出电压、电流和功率或可调内阻的调节，由两个旋钮完成。
旋钮可在不同菜单下更改数值。
为避免误操作，可锁定所有操作控制键。
Display and control panel
The adjustment of output voltage, output current and outputpower, or optional internal resistance, is realised by tworotary knobs. The rotary knobs are required for changingvalues in the different menus as well.
To prevent unintentional operations, all operation controlscan be locked.
函数管理器
函数由序列组成， 通过控制面板可对其进行修改。
一个函数由zui多5个序列组成，可按任意顺序排列， 重复次数zui多为5次。
每个序列可设置zui大功率或可选内阻， 重复次数为一至254次，或者无穷大。
同样地，整个函数段的重复次数可以设置成一至254次，或无穷大。
Function manager
Functions consist of sequences and can be modifed via the control panel.
Up to fve different sequences can be assigned to a function in any succession or be repeated up to fve times.
For each sequence, the maximum power, or optionally the internal resistance, and a repetition value from once up to 254 times or endless can be confgured.
As well, the repetition of a whole function can be confgured from once up to 254 times or endless.
用户配置文档
利用控制面板可存储多达四种用户配置文档。用户配置文档专门用来设置和存储用户的参数块。
User profles
Via the control panel up to four different user profles can be stored. The user profles are designed to set and save user specifed parameter blocks.

输出值的预设
在不影响输出状态的条件下设置输出值， 显示器上可先显示预设值，即实际值的下方。
这样用户可预设期望输出电压、 电流和功率。并在预设清单内存储4组U / I / P参数块。该清单内的参数块可上载作为常用需求值。

内置模拟接口
模拟接口位于产品后面板，供有模拟输入脚，接上0V...10V或0V...5V电压，可设置0...100%的输出电压、电流（ 1kW或更大功率型号） 。
模拟输出脚接上0V...10V或0V...5V电压，可监控输出电压和电流。此外， 还有几个输入和输出脚，可用来控制和监控产品状态。

选购件
可利用匹配RS232、 CAN、 USB、 GPIB (IEEE)、 Profbus或Ethernet/LAN的绝缘数字接口卡，经电脑控制产品。接口插槽位于产品后板，方便用户插上新接口或替换当前接口。产品会自动检测接口，并提示需要进行少许的配置或不用配置。随接口卡附有免费Windows软件，可用来控制和监控，记录数据和排序。也可参考63和64页。

内阻调整
高速跃变 (仅针对1kW以上产品，见118页)

Presetting of output values
To set output values without a direct reaction to the outputcondition, set values can be preset. They‘re shown on thedisplay, positioned below the actual values.
So the user can preset required values for voltage, currentand power. Also four parameter blocks for U / I / P can bedeposit in a preset list. From this list parameter blocks canbe loaded for frequently required values.
Built-in analogue interface
The analogue interface is located on the rear of the device.
It offers analogue inputs to set voltage, current and power(models from 1kW) from 0...100% through control voltagesof 0V...10V or 0V...5V.
To monitor output voltage and current, there are analogueoutputs with voltage ranges of 0V...10V or 0V...5V. Also,several inputs and outputs are available for controlling andmonitoring the device status.
Options
Isolated digital interface cards for RS232, CAN, USB,GPIB (IEEE), Profbus or Ethernet/LAN to control the device by PC. The interface slot is located on the rear panel,making it easy for the user to plug in a new interface orto replace an existing one. The interface will be automatically detected by the device and requires no or only littleconfguration. Included with the interface cards is a freeWindows software which provides control and monitoring,data logging and sequences. See pages 63 and 64.
