Schumacher 1483-0400A輸入流量控制器
外部輸入保護(hù)該裝置經(jīng)過測(cè)試，可用于20A以下的分支電路。僅當(dāng)供電支路的載流量大于此值時(shí)，才需要外部保護(hù)。在某些國家，當(dāng)?shù)胤ㄒ?guī)可能適用。還應(yīng)檢查當(dāng)?shù)匾?guī)范和當(dāng)?shù)匾?。如果需要或使用外部保險(xiǎn)絲，則需要最小值以避免保險(xiǎn)絲意外跳閘。并聯(lián)使用說明：單元A AC DC單元B AC DC-+-+負(fù)載+-A）僅使用同一系列（XLS）的電源。b） 將所有電源的輸出電壓調(diào)整至大致相同的值（±500mV）。否則，DC ok信號(hào)可能無法正常工作。c） 只有當(dāng)三個(gè)以上的裝置并聯(lián)時(shí)，才需要在輸出端安裝保險(xiǎn)絲（或二極管）。d） 不要給端子加載超過25A的電流。按照第27.9 e）節(jié)中的接線說明進(jìn)行操作。兩個(gè)電源之間保持15mm（左/右）的安裝間隙，避免將電源安裝在彼此的頂部。當(dāng)電源安裝在密封嚴(yán)密的外殼中時(shí)，外殼內(nèi)部的溫度將高于外部。內(nèi)部溫度定義電源的環(huán)境溫度。這種安裝的結(jié)果是：電源放在盒子的中間，盒子內(nèi)沒有其他熱發(fā)生器
并行使用以實(shí)現(xiàn)冗余
電源可以并聯(lián)以實(shí)現(xiàn)冗余，以獲得更高的系統(tǒng)可用性。冗余系統(tǒng)需要一定數(shù)量的額外電源，以在一個(gè)電源設(shè)備發(fā)生故障時(shí)支持負(fù)載。最簡單的方法是將兩個(gè)XLS電源并聯(lián)。這稱為1+1冗余。如果一個(gè)電源裝置發(fā)生故障，另一個(gè)電源可自動(dòng)支持負(fù)載電流而不會(huì)中斷。用于更高功率需求的冗余系統(tǒng)通常采用N+1方法構(gòu)建。E、 g.五個(gè)電源并聯(lián)，每個(gè)額定值為10A，以構(gòu)建40A冗余系統(tǒng)。請(qǐng)注意：這種構(gòu)建冗余系統(tǒng)的簡單方法不包括諸如電源二次側(cè)內(nèi)部短路之類的故障。在這種幾乎不可能的情況下，缺陷單元成為其他電源的負(fù)載，輸出電壓無法再維持。這只能通過使用解耦模塊1606-XLSRED中包含的解耦二極管來避免。構(gòu)建冗余電源系統(tǒng)的建議：a）為每個(gè)電源使用單獨(dú)的輸入保險(xiǎn)絲。b） 監(jiān)控各個(gè)電源設(shè)備。單元中已包含直流ok指示燈和直流ok觸點(diǎn)。此功能報(bào)告單元故障。c） 如果可能，將每個(gè)電源連接到不同的相位或電路。d） 最好將所有電源的輸出電壓設(shè)置為相同的值，以避免錯(cuò)誤的DC ok信號(hào)。27.9.只要通過一個(gè)端子引腳的最大電流不超過25A，就允許菊花鏈（從一個(gè)電源輸出跳到下一個(gè)）。如果電流較高，請(qǐng)使用單獨(dú)的配電接線板。
EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 20A. External protection is only required if the supplying branch has an ampacity greater than this. In some countries local regulations might apply. Check also local codes and local requirements. If an external fuse is necessary or utilized, a minimum value is required to avoid undesired tripping of the fuse.Instructions for parallel use: Unit A AC DC Unit B AC DC - + - + Load + - a) Use only power supplies from the same series (XLS). b) Adjust the output voltages of all power supplies to approximately the same value (±500mV). Otherwise, the DC-ok signal might not work properly. c) A fuse (or diode) on the output is only required if more than three units are connected in parallel. d) Do not load terminals with more than 25A. Follow wiring instructions according to section 27.9 e) Keep an installation clearance of 15mm (left/right) between two power supplies and avoid installing the power supplies on top of each other.When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. The inside temperature defines the ambient temperature for the power supply. Results from such an installation: Power supply is placed in the middle of the box, no other heat producer inside the box
PARALLEL USE FOR REDUNDANCY
Power supplies can be paralleled for redundancy to gain a higher system availability. Redundant systems require a certain amount of extra power to support the load in case one power supply unit fails. The simplest way is to put two XLS power supplies in parallel. This is called a 1+1 redundancy. In case one power supply unit fails, the other one is automatically able to support the load current without any interruption. Redundant systems for a higher power demand are usually built in a N+1 method. E.g. Five power supplies, each rated for 10A are paralleled to build a 40A redundant system. Please note: This simple way to build a redundant system does not cover failures such as an internal short circuit in the secondary side of the power supply. In such a - virtually nearly impossible - case, the defect unit becomes a load for the other power supplies and the output voltage can not be maintained any more. This can only be avoided by utilizing decoupling diodes which are included in the decoupling module 1606-XLSRED. Recommendations for building redundant power systems: a) Use separate input fuses for each power supply. b) Monitor the individual power supply units. A DC-ok lamp and a DC-ok contact is already included in the units This feature reports a faulty unit. c) When possible, connect each power supply to different phases or circuits. d) It is desirable to set the output voltages of all power supplies to the same value to avoid a false DC-ok signal. 27.9. DAISY CHAINING OF OUTPUTS Daisy chaining (jumping from one power supply output to the next) is allowed as long as the maximum current through one terminal pin does not exceed 25A. If the current is higher, use a separate distribution terminal block.
