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 以上型號輸出功率可靈活調整。可在低電流時輸出更高的電壓，或在低電壓時輸出更大的電流，都由zui大額定輸出功率來限制。 因此一臺該產品能涵蓋廣范圍的應用領域。設定功率可從0..100%之間可調，或手動調節或遠程控制。 1.5kW型號產品有功率降額功能，即： 在較低輸入電壓時減少zui大輸出功率。
輸入
本系列所有型號都采用主動式功率因數校正線路， 1.5kW以下產品在為 90V 至 264V AC 輸入電壓下都可使用。
直流輸出
本系列有多款不同型號，可選擇0...32V和0...720V輸出電壓， 0...4A和0...120A輸出電流， 640W和0...3000W輸出功率的類型。
輸出端位于產品后板。
針對電壓由高至低快速躍變的應用， 1kW以上且電壓在400V以下的型號，可配上兩象限功率降額模塊（有源負載）完成該操作。
通過功率降額模塊對電源內部濾波電容和連接負載的輸入濾波電容快速放電， 實現電壓的快速變化。
過壓保護 (OVP)
為保護連接負載，可設定一過壓保護極限值 (OVP)。
若輸出電壓超過調節極限值， 輸出被關斷， 顯示器和模擬接口發出一聲頻報警信號。
報警管理系統
為監控正確的輸出電壓和電流，可定義上、下限。
若偏差超過該調節極限，應用設備會出現下列三種可能性反應：
- 只顯示信號；即使錯誤仍存在，也不影響輸出。
- 警告一直持續， 消除錯誤后必須確認警告信息。
- 報警會暫時關斷輸出。
報警和警告發出聲音信號。
遠程感測端
遠程感測輸入端可直接連到負載設備，以補償連線上的壓降。 如果輸入端已接上負載，本電源會自動調整輸出電壓，以確保負載獲得準確所需的電壓值。
顯示和控制鍵
輸出電壓、 電流和功率的設定值、實際值都顯示于圖形顯示器上， 還包括產品的運作狀態， 菜單指引和按鈕當前功能，故用戶能直觀地操作本產品。EA-PSI 8000 2U 640W - 3000W
顯示器和控制面板
輸出電壓、電流和功率或可調內阻的調節，由兩個旋鈕完成。
旋鈕可在不同菜單下更改數值。
為避免誤操作，可鎖定所有操作控制鍵。
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.
函數管理器
函數由序列組成， 通過控制面板可對其進行修改。
一個函數由zui多5個序列組成，可按任意順序排列， 重復次數zui多為5次。
每個序列可設置zui大功率或可選內阻， 重復次數為一至254次，或者無窮大。
同樣地，整個函數段的重復次數可以設置成一至254次，或無窮大。
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.
用戶配置文檔
利用控制面板可存儲多達四種用戶配置文檔。用戶配置文檔專門用來設置和存儲用戶的參數塊。
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.
輸出值的預設
在不影響輸出狀態的條件下設置輸出值， 顯示器上可先顯示預設值，即實際值的下方。
這樣用戶可預設期望輸出電壓、 電流和功率。并在預設清單內存儲4組U / I / P參數塊。該清單內的參數塊可上載作為常用需求值。
內置模擬接口
模擬接口位于產品后面板，供有模擬輸入腳，接上0V...10V或0V...5V電壓，可設置0...100%的輸出電壓、電流（ 1kW或更大功率型號） 。
模擬輸出腳接上0V...10V或0V...5V電壓，可監控輸出電壓和電流。此外， 還有幾個輸入和輸出腳，可用來控制和監控產品狀態。
選購件
可利用匹配RS232、 CAN、 USB、 GPIB (IEEE)、 Profbus或Ethernet/LAN的絕緣數字接口卡，經電腦控制產品。接口插槽位于產品后板，方便用戶插上新接口或替換當前接口。產品會自動檢測接口，并提示需要進行少許的配置或不用配置。隨接口卡附有免費Windows軟件，可用來控制和監控，記錄數據和排序。也可參考63和64頁。

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.
