In all cases it is the responsibility of the user to employ safe working practices and verify that the system is safe before connection. Even isolated systems may exhibit significant capacitance which will become highly charged during the application of the insulation test. This charge can be lethal and connections, including the leads and clips, should never be touched during the test. The system must be safely discharged before touching connections.DESIGNED FOR EVERYDAY USETest leads are a key component of any precision instrument and that safety, long life, and the ability to provide reliable connections to a variety of test pieces found in everyday applications are of the utmost importance. Megger design test leads for both safety and practical operation.LOCKING HV INSULATED PLUGS/NON-REMOVABLE TEST CLIPSAll Megger 5 kV, 10 kV and 15 kV insulation testing test leads are fitted with unique locking HV plugs and non-removable test clips. This reduces the likelihood of a plug or clip inadvertently losing electrical connection and the capacitance of a long cable remaining lethally charged.With the arrows on the plug finger guard horizontal on the instrument as shown to lock. Twist 90º to to unlock. In addition,for the same reason, the test clips are not removable from the test lead.PRACTICAL INSULATION DESIGNMoving jaw fingers maintain the clips touch proof safety when clip is closed but flex back to allow metal teeth of the clip to contact test piece unimpeded when in use.Megger clip beingtested with IECstandard testfinger for creepageand clearance.PRACTICAL JAW DESIGNCurved jaws allow reliable connection around test piecesand flat jaw tips provide excellent connection and grippingof individual wires.OPTIONAL TEST LEADSMEDIUM AND LARGE TEST CLIPSTest leads above with medium and large size insulated clips are available supplied as an option in 5m, 8m, 10m and 15m lengths.

MAX44242 低输入偏置电流、低噪声操作放大器 (OP 放大器) 评估套件说明书
General DescriptionThe MAX44242 evaluation kit (EV kit) provides a prov-en design to evaluate the MAX44242 low-input biascurrent, low-noise operational amplifier (op amp) in an8-pin µMAX ® package. The EV kit circuit is preconfig-ured as noninverting amplifiers, but can be adapted toother topologies by changing a few components. Thecomponent pads accommodate 0805 packages, makingthem easy to solder and replace. The EV kit comes with aMAX44242AUA+ installed.Features and Benefits●Accommodates Multiple Op-Amp Configurations●Rail-to-Rail Outputs●Accommodates Easy-to-Use 0805 Components● 2.7V to 20V Single Supply or ±1.35V to Q 10V DualSupplies●Proven PCB Layout●Fully Assembled and TestedQuick StartRequired Equipment●MAX44242 EV kit●+5V, 10mA DC power supply (PS1)●Two precision voltage sources●Two digital multimeters (DMMs)Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation:1) Verify that the jumpers are in their default position, as shown in Table 1.2) Connect the positive terminal of the +5V supply to VDD and the negative terminal to GND and VSS.3) Connect the positive terminal of the precision voltage source to INAP . Connect the negative terminal of the precision voltage source to GND.4) Connect INAM to GND.5) Connect the positive terminal of the second precision voltage source to the INBP pad. Connect the nega-tive terminal of the precision voltage source to GND.6) Connect INBM to GND.7) Connect the DMMs to monitor the voltages on OUTA and OUTB. With the 10kΩ feedback resistors and 1kΩ series resistors, the gain of each noninverting amplifier is +11.8) Turn on the +5V power supply.9) Apply 100mV from the precision voltage sources. Observe the output at OUTA and OUTB on the DMMs. Both should read approximately +1.1V.10) Apply 400mV from the precision voltage sources. Both OUTA and OUTB should read approximately +4.4V.19-6917; Rev 0; 2/14Ordering Information appears at end of data sheet.μMAX is a registered trademark of Maxim Integrated Products, Inc.Detailed Description of HardwareThe MAX44242 EV kit provides a proven layout for theMAX44242 low input bias current, low-noise dual op amp.The IC is a single-supply dual op amp whose primaryapplication is operating in the noninverting configuration;however, the IC can operate with a dual supply as long asthe voltage across the VDD and GND pins of the IC do notexceed the absolute maximum ratings. When operatingwith a single supply, short VSS to GND.Op-Amp Configurations The IC is a single-supply dual op amp ideal for differential sensing, noninverting amplification, buffering, and filter-ing. A few common configurations are shown in the next few sections.The following sections explain how to configure one of the device’s op amps (op-amp A). To configure the device’s second op amp (op-amp B), the same equations can be used after modifying the component reference designa-tors. For op-amp B, the equations should be modified by adding 10 to the number portion of the reference designa-tors (e.g., for the noninverting configuration, equation R1 becomes R11 and R5 becomes R15).Noninverting ConfigurationThe EV kit comes preconfigured as a noninvertingamplifier. The gain is set by the ratio of R5 and R1. TheEV kit comes preconfigured for a gain of +11. The outputvoltage for the noninverting configuration is given by the equation below:OUTA INAP R5V 1V R1 =+ *Default position.JUMPERSHUNT POSITION DESCRIPTION JU1Installed*Connects INAM to R1. Also shorts capacitor C5.OpenConnects INAM to R1 through capacitor C5. When AC-coupling is desired, remove the shunt and install capacitor C5. JU2Installed*Connects INAP to JU3 position 1. Also shorts capacitor C6. OpenConnects INAP to JU3 position 1 through capacitor C6. When AC-coupling is desired, remove the shunt and install capacitor C6.

When AC-coupling is desired, remove the shunt and install capacitor C10. JU5Installed*Connects INBM to R11. Also shorts capacitor C15. OpenConnects INBM to R11 through capacitor C15. When AC-coupling is desired, remove the shunt and install capacitor C15. JU6Installed*Connects INBP to JU6 position 1. Also shorts capacitor C16. OpenConnects INBP to JU6 position 1 through capacitor C16. When AC-coupling is desired, remove the shunt and install capacitor C16. JU71-2*Connects INBP to JU7 and C16 through R12 and R182-3Connects INBP to GND through R12 and R18JU8Installed*Connects OUTB to OUTB Open Connects OUTB to OUTB through capacitor C20. When AC-coupling is desired, remove the shunt and install capacitor C20.R1–R3, and R5 with appropriate resistors. WhenR1 = R2 and R3 = R5, the CMRR of the differential ampli-fier is determined by the matching of the resistor ratiosR1/R2 and R3/R5.OUTA INAP INAM V GAIN (V V )=−where:R5R3GAIN R1R2==Sallen-Key Filter ConfigurationThe Sallen-Key filter topology is ideal for filtering sensorsignals with a second-order filter and acting as a buffer.Schematic complexity is reduced by combining the filterand buffer operations. The EV kit can be configured ina Sallen-Key topology by replacing and populating afew components. The Sallen-Key topology is typicallyconfigured as a unity-gain buffer, which can be done byreplacing R1 and R5 with 0Ω resistors and short JU2. Thenoninverting signal is applied to the INAP test point withJU2 short and short pins 1-2 on JU3 or do the same on theINBP pad similarly. The filter component pads are R2–R4,and R8, where some have to be populated with resistorsand others with capacitors.Lowpass Sallen-Key FilterTo configure the Sallen-Key as a lowpass filter, populatethe R2 and R8 pads with resistors, and populate the R3and R4 pads with capacitors. The corner frequency and Qare then given by:C R3R2R8f Q ==the R3 and R4 pads with resistors and populate the R2 and R8 pads with capacitors. The corner frequency and Qare then given by:C R4R2R8f Q ==Transimpedance Application To configure op-amp U1-A as a transimpedance amplifier (TIA), replace R1 with a 0Ω resistor and install a shunt on jumper JU1 and shunt on pins 2-3 on jumper JU3. The output voltage of the TIA is the input current multiplied by the feedback resistor:OUT IN BIAS OS V (I I )R4V =+×+where R4 is installed as a 10kΩ resistor, I IN is defined as the input current source applied at the INAM pad, I BIAS is the input bias current, and V OS is the input offset voltage of the op amp. Use capacitor C8 (and C7, if applicable) to stabilize the op amp by rolling off high-frequency gain due to a large cable capacitance. Similarly, we can configure op-amp U1-B for transimpedance application.Capacitive Loads Some applications require driving large capacitive loads. To improve the stability of the amplifier, replace R6 (R16 for U1-B) with a suitable resistor value to improve ampli-fier phase margin. The R6/C9 (R16/C19 for U1-B) filter can also be used as an anti-alias filter, or to limit amplifier output noise by reducing its output bandwidth.DESIGNATION QTY DESCRIPTIONC1, C320.1µF ±10%, 25V X7R ceramic capacitors (0805)C2, C424.7µF ±10%, 25V X5R ceramic capacitors (0805)C5–C10, C15–C200Not installed, ceramic capacitors(0805)GND2Black test points INAM, INAP,INBM, INBP,OUTA, OUTB,VDD, VSS8Red test pointsJU1, JU2,JU4–JU6, JU862-pin headers JU3, JU723-pin headers DESIGNATION QTY DESCRIPTION R1, R2,R11, R1241kΩ ±1% resistors (0805)R3, R4, R7,R13, R14, R170Not installed, resistors (0805) R5, R15210kΩ ±1% resistors (0805)R6, R8,R16, R1840Ω ±5% resistors (0805) TP1, TP20Not installed, miniature test points U11Dual low-power, rail-to-rail I/O opamp (8 µMAX)Maxim MAX44242AUA+—8Shunts—1PCB: MAX44242 EVKITFigure 1.

菲尼克斯电气产品介绍
菲尼克斯电气简介菲尼克斯电气中国公司隶属于德国菲尼克斯电气集团。
菲尼克斯中国是一个综合化的电器电子元器件公司，1993年成立于中国，其主体产业遍及化工、冶金、通讯、物流，造纸、汽车制造、烟草机械，以及风力发电和能源制造等领域，共计6万多种产品，年营业额达10亿欧元。
菲尼克斯设有三大竞争力中心，分别建在德国、美国和中国。
菲尼克斯中国有20多个办事处，在中国交通运输发展中的部件供应上有着重要作用。
1公司简介近两年来，中国经济作用下，轨道交通蓬勃发展，在全球电力输配电连接器领域占70%市场份额的菲尼克斯电气，也已经开始进军这个产业。
菲尼克斯电气主要为西门子等提供大量的子系统和零部件，它拥有6万多种产品，有人曾经开玩笑的说：如果把菲尼克斯电气的产品加到一起，那就相当于一个微缩版的西门子自动化控制驱动集团。
然而，即便如此，菲尼克斯电气却始终没有打造成品的念头。
2发展历程1993年菲尼克斯电气来到中国南京，建立了一个从管理层到员工100%本土化的队伍，在我们的共同努力以及各界朋友的帮助与支持下，17年来，菲尼克斯中国公司的员工总数增加了10倍，投资增长了50多倍，产出增长了350多倍！2005年销售额超过8个亿，2009年销售额已经超过12亿，当前拥有3个公司、18个办事处（2010年，有4个公司，23个办事处），先后被评选为“中国电气工业100强”、“中国最具竞争力的高成长型创业企业500强”、“全国企业文化建设特别贡献奖”、“全国客户满意单位”等等。
南京菲尼克斯路和凤凰坛的冠名，更是一座里程碑。
尤其是凤凰坛，这是迄今为止全国唯一一座以企业名字冠名的城市标志性建筑。
3大环境过去，德国在华企业一共才有7000多家，不算特别多但是这个数字已经翻了很多倍。
那个时候，中国的制作产业才刚刚开始发展，投资并不像今天那么多，在中国运行一个品牌并不是一件容易的事。
菲尼克斯电气的很多产品是围绕工厂自动化做的，轨道交通行业很特别，中国的轨道交通更为特别。
