产品详情介绍
HIEE300024R4信号处理板
本手册包含操作和维护说明，包括电子测量，股份有限公司型号EMHP系列三相可控硅控制电源。这些电源是稳压/恒流、自动交叉稳压直流电源，封装在全封闭钢和铝柜中。电压模式-对于电源额定值内的线路电压变化或负载电流变化，输出电压的变化不会超过最大额定电流的0.1%。电流模式-对于电源额定值内的线路电压变化或负载电压变化，输出电流的变化不会超过最大额定电流的0.1%。在电压或电流纹波百分比超过规定调节的装置上，由于纹波对测量的影响，调节似乎会降低。1.2.3稳定性：预热后8小时内，输出电压或电流将保持在0.05%以内，外部效应恒定。1.2.4纹波：在正极或负极输出端子接地且100%输出电压和电流进入电阻负载的情况下测量。（见评级表）。由±10%的线路变化和/或额定限值50%到100%之间的负载变化引起的输出变化通常会在200 ms内恢复到其最终值的1%以内。前、后和侧面板都涂成褐色。面板标记为黑色丝网。底盘框架和顶盖漆成黑色。所有其他金属部件都经过电镀或化学膜处理。零件号确定零件号有4个部分，用于确定电源的电压输出、电流容量和选项。例如，以下型号解释如下：EMHP 40-600-42212 EMHP=电源类型40=电压范围600=电流范围

拆包小心地移除包装板条箱的顶部和侧面以及底部的任何支撑或衬垫材料，这些材料也可用作托盘。电源通过四个3/8“-16螺栓连接到板条箱底部。脚轮（如果配备）与其安装硬件分开包装。2.2目视检查立即检查电源是否有任何运输损坏。验证以下内容：a.检查前面板控制装置的操作（旋钮应平稳旋转）。b。确认断路器锁定在接通和断开位置。c、 确认面板表面没有凹痕或划痕。d、 检查前面板仪表和LED是否有任何破损或破裂的玻璃。如果发现任何损坏，请遵循“装运损坏索赔”说明。2.3机械-该电源用于地板安装，有或没有脚轮或工字梁。无论是否安装在托盘上，都可以用叉车提升。如果不使用托盘，叉车铲刀必须完全伸出底座下方，以便支撑两侧。可以用合适的吊环螺栓（除非另有规定，否则不提供）代替四个顶盖螺栓来起吊电源。确保相邻设备不会阻塞进气口或排气口。除测试目的外，此电源不应在移除盖子的情况下运行。2.4电气-该电源需要规定电压和频率的三相输入，具有线对线标称电压（三线制）。将电源线连接到电源的输入端子时，无需遵守相位旋转顺序。无需中性连接，但为了安全起见，标有GRD的底盘接地端子应连接至接地。根据电气规范要求，应在该电源的电源线中安装具有适当中断额定值的分支电路隔离开关或插头。
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.
