HIEE300024R4信號處理板
本手冊包含操作和維護說明，包括電子測量，股份有限公司型號EMHP系列三相可控硅控制電源。這些電源是穩(wěn)壓/恒流、自動交叉穩(wěn)壓直流電源，封裝在全封閉鋼和鋁柜中。電壓模式-對于電源額定值內(nèi)的線路電壓變化或負載電流變化，輸出電壓的變化不會超過最大額定電流的0.1%。電流模式-對于電源額定值內(nèi)的線路電壓變化或負載電壓變化，輸出電流的變化不會超過最大額定電流的0.1%。在電壓或電流紋波百分比超過規(guī)定調(diào)節(jié)的裝置上，由于紋波對測量的影響，調(diào)節(jié)似乎會降低。1.2.3穩(wěn)定性：預(yù)熱后8小時內(nèi)，輸出電壓或電流將保持在0.05%以內(nèi)，外部效應(yīng)恒定。1.2.4紋波：在正極或負極輸出端子接地且100%輸出電壓和電流進入電阻負載的情況下測量。（見評級表）。由±10%的線路變化和/或額定限值50%到100%之間的負載變化引起的輸出變化通常會在200 ms內(nèi)恢復(fù)到其最終值的1%以內(nèi)。前、后和側(cè)面板都涂成褐色。面板標記為黑色絲網(wǎng)。底盤框架和頂蓋漆成黑色。所有其他金屬部件都經(jīng)過電鍍或化學(xué)膜處理。零件號確定零件號有4個部分，用于確定電源的電壓輸出、電流容量和選項。例如，以下型號解釋如下：EMHP 40-600-42212 EMHP=電源類型40=電壓范圍600=電流范圍

拆包小心地移除包裝板條箱的頂部和側(cè)面以及底部的任何支撐或襯墊材料，這些材料也可用作托盤。電源通過四個3/8“-16螺栓連接到板條箱底部。腳輪（如果配備）與其安裝硬件分開包裝。2.2目視檢查立即檢查電源是否有任何運輸損壞。驗證以下內(nèi)容：a.檢查前面板控制裝置的操作（旋鈕應(yīng)平穩(wěn)旋轉(zhuǎn)）。b。確認斷路器鎖定在接通和斷開位置。c、 確認面板表面沒有凹痕或劃痕。d、 檢查前面板儀表和LED是否有任何破損或破裂的玻璃。如果發(fā)現(xiàn)任何損壞，請遵循“裝運損壞索賠”說明。2.3機械-該電源用于地板安裝，有或沒有腳輪或工字梁。無論是否安裝在托盤上，都可以用叉車提升。如果不使用托盤，叉車鏟刀必須完全伸出底座下方，以便支撐兩側(cè)?？梢杂煤线m的吊環(huán)螺栓（除非另有規(guī)定，否則不提供）代替四個頂蓋螺栓來起吊電源。確保相鄰設(shè)備不會阻塞進氣口或排氣口。除測試目的外，此電源不應(yīng)在移除蓋子的情況下運行。2.4電氣-該電源需要規(guī)定電壓和頻率的三相輸入，具有線對線標稱電壓（三線制）。將電源線連接到電源的輸入端子時，無需遵守相位旋轉(zhuǎn)順序。無需中性連接，但為了安全起見，標有GRD的底盤接地端子應(yīng)連接至接地。根據(jù)電氣規(guī)范要求，應(yīng)在該電源的電源線中安裝具有適當中斷額定值的分支電路隔離開關(guān)或插頭。
This manual contains operation
and maintenance instructions covering the Electronic Measurements, Inc. model EMHP series three-phase SCR controlled power supplies. These supplies are constant voltage/constant current, automated crossover sources of regulated DC power, packaged in fully enclosed steel and aluminum cabinets.Voltage Mode - For line voltage variations or load current variations within the rating of the supply, the output voltage will not vary more than 0.1% of the maximum current rating. Current Mode - For line voltage variations or load voltage variations within the rating of the supply, the output current will not vary more than 0.1% of the maximum current rating. On those units in which the percentage of voltage or current ripple exceeds the specified regulation, the regulation will appear to be degraded due to the effect of this ripple on the measurement. 1.2.3 STABILITY: The output voltage or current will remain within 0.05% for 8 hours after warm-up, with constant external effects. 1.2.4 RIPPLE: Measured with either positive or negative output terminal grounded and 100% output voltage and current into a resistive load. (See rating sheet).Output variations, caused by line variations of ± 10%, and/or load variations between 50% and 100% of rated limits, will typically recover to within 1% of its final value within 200 ms.Front, rear and side panels are painted tan. Panel markings are silk-screened in black. Chassis frame and top cover are painted black. All other metallic parts are either plated or chemical film treated.PART NUMBER DETERMINATION The part number has 4 sections which determine the voltage output, the current capability and the options which go in a power supply. For example, the following model number is interpreted as follows: EMHP 40-600-42212 EMHP = Type of power supply 40 = Voltage range 600 = Current range
UNPACKING
Carefully remove the top and sides of the packing crate and any bracing or padding material from the bottom, which also serves as a pallet. The power supply is attached to the crate bottom by four 3/8"-16 bolts. Casters (if so equipped) are packed separately with their mounting hardware. 2.2 VISUAL INSPECTION Immediately inspect the power supply for any shipping damage. Verify the following: a. Check the operation (knobs should rotate smoothly) of the front panel controls. b. Verify that the circuit breaker latches in the ON and OFF positions. c. Confirm that there are no dents or scratches on the panel surfaces. d. Check front panel meters and LEDs for any broken or cracked glass. If any damage is found, follow the "Claim for Damage in Shipment" instructions. 2.3 MECHANICAL This power supply is intended for floor mounting, with or without casters or I-Beams. It can be fork lifted whether it is mounted on a pallet or not. If a pallet is not used, the fork lift blades must extend fully under the base so that both sides are supported. The power supply may be hoisted by substituting suitable lifting eye bolts (not supplied unless specified) for the four top cover bolts.Make sure that adjacent equipment does not block air intake or exhaust openings. Except for test purposes, this power supply should not be operated with covers removed. 2.4 ELECTRICAL This power supply requires a three-phase input of the specified voltage and frequency, with nominal voltage line-to-line (three-wire system). Phase rotation sequence need not be observed when connecting the power line to input terminals of the power supply. No neutral connection is required, but for safety, the chassis ground terminal marked GRD should be connected to earth ground. A branch circuit disconnecting switch or plug having a suitable interrupting rating should be installed in the power line to this power supply in accordance with electrical code requirements. For input wire size, see a wire table.
