UR8GH保護(hù)繼電器
一次打開一個(gè)單元直到電源電流能力的總和超過所消耗的負(fù)載電流。5.使用電壓控制平衡每個(gè)單元電壓，以獲得相等的輸出電流。6.將電流控制設(shè)置為僅限制在運(yùn)行電流之上，這樣，如果一個(gè)裝置的輸出電壓向上漂移，它就會(huì)受到電流限制，而不是承載過多的負(fù)載電流份額。重要事項(xiàng)：當(dāng)裝置包含過電壓選項(xiàng)時(shí)，未經(jīng)咨詢電子測量工程人員，請勿將其并聯(lián)。如果其中一個(gè)并聯(lián)單元在未正確并聯(lián)OVP選項(xiàng)的情況下進(jìn)入過電壓，將發(fā)生不可修復(fù)的損壞。在此配置中，指定為主電源的電源用于控制所有其他電源（稱為從電源）的電壓和電流操作。1.斷開所有從機(jī)的以下跳線：TB3-13和14 TB3-9、10和11 2.在所有從機(jī)TB3-10和12之間連接跳線。3.如圖9A或9B所示，連接每個(gè)電源的主電源TB3-12和TB3-13。4.將每個(gè)從機(jī)的電壓控制調(diào)整到最大CW。5.正負(fù)電壓連接見圖9A或9B。6.打開每個(gè)從屬設(shè)備，然后打開主設(shè)備。7.根據(jù)需要的輸出電壓或電流調(diào)整主控。每個(gè)電源的輸出引線必須對(duì)電源附近的負(fù)載點(diǎn)具有相等的電阻，以確保均勻分配。
串聯(lián)操作
只需將一個(gè)單元的負(fù)極輸出端子連接到另一個(gè)單元正極輸出端子，即可串聯(lián)兩個(gè)EMHP電源。每個(gè)單元的調(diào)節(jié)功能獨(dú)立，總輸出電壓是每個(gè)單元輸出電壓的總和。注意：任何輸出端子上的電壓相對(duì)于底盤接地不得超過600V。請咨詢Electronic Measurements，股份有限公司工程部，了解兩個(gè)以上電源的串聯(lián)操作。遠(yuǎn)程儀表遠(yuǎn)程電壓表可連接在端子TB3-2（位置）和TB3-7（負(fù)極）之間。如果同時(shí)使用遙感，遠(yuǎn)程電壓表將指示負(fù)載電壓。為了指示電源輸出端子處的電壓，在端子TB3-1（位置）和TB3-8（負(fù)極）之間連接遠(yuǎn)程電壓表。遠(yuǎn)程毫伏表可連接在端子TB3-12（負(fù)極）和TB3-14（位置）之間。除非另有規(guī)定，否則這些端子上的0至100毫伏電壓表示輸出電流從零到滿額定值（見主示意圖）。為了補(bǔ)償遠(yuǎn)程長電流表引線中的電壓降，將滿標(biāo)度靈敏度小于100毫伏的電流表移動(dòng)裝置與校準(zhǔn)電阻器串聯(lián)使用。遠(yuǎn)程儀表的導(dǎo)線應(yīng)扭曲，如果存在強(qiáng)交流或射頻場，則應(yīng)屏蔽導(dǎo)線。屏蔽的一端應(yīng)接地至端子TB3-14，另一端保持浮動(dòng)
Turn units on one at a time
until the sum of the power supply current capabilities exceeds the load current drawn. 5. Using the voltage controls balance each unit voltage for equal output current. 6. Set the current controls to limit just above running current so that if a unit's output voltage drifts upward, it will become current limited rather than carry an excessive share of load current. IMPORTANT: When the units contain the overvoltage option do not connect them in parallel without consulting the Engineering Staff of Electronic Measurements. Irreparable damage will occur if one of the paralleled units goes into overvoltage without proper paralleling of the OVP option.In this configuration, the power supply designated the master is used to control the voltage and current operation of all other supplies, referred to as slaves. 1. Disconnect the following jumpers of all slaves: TB3-13 and 14 TB3-9, 10 and 11 2. Connect a jumper between TB3-10 and 12 of all slaves. 3. Connect the master supply TB3-12 and TB3-13 of each supply as shown in either Figure 9A or 9B. 4. Adjust the voltage control of each slave to maximum CW. 5. See Figure 9A or 9B for + and - voltage connection. 6. Turn each slave on and then the master. 7. Adjust the master for required output voltage or current. The output leads from each power supply must be of equal resistance to a point of load near the supply to assure equal sharing.
SERIES OPERATION
Two EMHP power supplies can be operated in series simply by connecting the negative output terminal of one unit to the positive output terminal of the other. The adjustment of each unit functions independently and the total output voltage is the sum of each unit output voltage. NOTE: The voltage at any output terminal must never exceed 600V with respect to chassis ground. Consult Electronic Measurements, Inc. Engineering Department for series operation of more than two supplies.REMOTE METERS A remote voltmeter may be connected between terminals TB3-2 (pos.) and TB3-7 (neg.). If remote sensing is also being used, the remote voltmeter will indicate the voltage at the load. To indicate the voltage at the power supply output terminals connect the remote voltmeter between terminals TB3-1 (pos.) and TB3-8 (neg.). A remote millivoltmeter may be connected between terminals TB3-12 (neg.) and TB3-14 (pos.). A voltage of 0 to 100mv across these terminals indicates output current from zero to full rating unless otherwise specified (see main schematic). To compensate for voltage drops in long remote ammeter leads a meter movement having a full-scale sensitivity of the less than 100mv is used in series with a calibrating resistor. The leads to the remote meters should be twisted, and if strong AC or RF fields are present, the leads should be shielded. One end of the shield should be grounded to terminal TB3-14 and the other end left floating
