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(hào)輸出功率可靈活調(diào)整。可在低電流時(shí)輸出更高的電壓，或在低電壓時(shí)輸出更大的電流，都由zui大額定輸出功率來(lái)限制。 因此一臺(tái)該產(chǎn)品能涵蓋廣范圍的應(yīng)用領(lǐng)域。設(shè)定功率可從0..100%之間可調(diào)，或手動(dòng)調(diào)節(jié)或遠(yuǎn)程控制。 1.5kW型號(hào)產(chǎn)品有功率降額功能，即： 在較低輸入電壓時(shí)減少zui大輸出功率。

輸入
本系列所有型號(hào)都采用主動(dòng)式功率因數(shù)校正線路， 1.5kW以下產(chǎn)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(hào)，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(chǎn)品后板。
針對(duì)電壓由高至低快速躍變的應(yīng)用， 1kW以上且電壓在400V以下的型號(hào)，可配上兩象限功率降額模塊（有源負(fù)載）完成該操作。

過(guò)壓保護(hù) (OVP)
為保護(hù)連接負(fù)載，可設(shè)定一過(guò)壓保護(hù)極限值 (OVP)。
若輸出電壓超過(guò)調(diào)節(jié)極限值， 輸出被關(guān)斷， 顯示器和模擬接口發(fā)出一聲頻報(bào)警信號(hào)。

報(bào)警管理系統(tǒng)
為監(jiān)控正確的輸出電壓和電流，可定義上、下限。
若偏差超過(guò)該調(diào)節(jié)極限，應(yīng)用設(shè)備會(huì)出現(xiàn)下列三種可能性反應(yīng)：
- 只顯示信號(hào)；即使錯(cuò)誤仍存在，也不影響輸出。
- 警告一直持續(xù)， 消除錯(cuò)誤后必須確認(rèn)警告信息。
- 報(bào)警會(huì)暫時(shí)關(guān)斷輸出。
報(bào)警和警告發(fā)出聲音信號(hào)。

遠(yuǎn)程感測(cè)端
遠(yuǎn)程感測(cè)輸入端可直接連到負(fù)載設(shè)備，以補(bǔ)償連線上的壓降。 如果輸入端已接上負(fù)載，本電源會(huì)自動(dòng)調(diào)整輸出電壓，以確保負(fù)載獲得準(zhǔn)確所需的電壓值。

顯示和控制鍵
輸出電壓、 電流和功率的設(shè)定值、實(shí)際值都顯示于圖形顯示器上， 還包括產(chǎn)品的運(yùn)作狀態(tài)， 菜單指引和按鈕當(dāng)前功能，故用戶能直觀地操作本產(chǎn)品。EA-PSI 8000 2U 640W - 3000W

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.
