12 The Official Daily Tag 1 – Dienstag 12 November 2024 Connectors Power Supplies ❚ Siglent New fourchannel DC power supplies Siglent introduces the SPD4000X series programmable linear DC power supply This series includes three models with the minimum resolution of 1 mV 1 mA and four independent programmable outputs and the total output power is 240 W 285 Wor 400 W For more voltage or current output CH2 and CH3 can internally be connected in series or in parallel by one button click The included 4-wire remote voltage compensation sense function can compensate voltage to ensure the stability and accuracy of the voltage at the device under test The SPD4000X series power supply is an ideal tool for device testing and can be widely used in power electronics manufacturing wireless communications or consumer electronics applications The SPD4000X series adds higher power flexibility accuracy and a fourth channel without occupying more space to our popular line of linear DC power supplies from Siglent The SPD4000X supports fivedigit voltage and fivedigit current display with excellent setting and read back resolution of 1 mV 1 mA Four output channels can be independently controlled but also turned on or off simultaneously Series and parallel functions allow two channels combined into one output with more power output capability Furthermore CH2 and CH3 can use the included 4-wire sense mode which can automatically compensate for the voltage drop of the positive and negative output lines ensuring that the voltage at the remote device to be tested is equal to the set voltage of the power supply It can realize the maximum compensation voltage of 0 6 Vin high precision test or long cable test Output response time is the time required for the voltage to return to the set range when the load current suddenly changes The SPD4000X series achieves a fast output response time of < 50 µs enabling fast compensation for output voltage changes By editing the singlestep setting value and duration the list function can generate multiple sequences to meet complex test requirements Users can edit the sequence by 50 steps with eight sets of builtin list sequence files Voltage Current Time etc can be set directly in each List which can be excellent for simulating a variety of voltage and current states such as sudden rise and fall interruption For complex waveforms which are difficult to edit List Bild Siglent sequence files can be imported via USB to improve test setup efficiency List time accuracy <50 ms setting resolution 1 ms with fast voltage rise fall time and very short voltage change time can meet the user‘s fine requirements for pulse voltage testing The SPD4000X series is equipped with a 4 3-inch true color TFT-LCD display Four channels of voltage and current waveform run chart can be set users can observe the waveform run chart through the colors corresponding to the channels to understand the output status of the four channels The SPD4000X series allows users to save multiple types of files to local or external memory for later recall It supports saving of output voltage current values independent series parallel output mode and can take a screen shot by long pressing the Save Recall key in any state which is very beneficial for capturing dynamic test conditions The power supply includes USB and LAN communication interfaces as standard and a USB-GPIB converter module as optional The embedded Web Server enables control and monitor of the power supply directly from a web browser eliminating the need to install software drivers or applications nw Siglent Hall A3 Booth 435 ❚ Würth Elektronik eiSos Data and power transmission with SPoE The SPoE reference design from Würth Elektronik is an easytoimplement EMCcompliant 10 Mbit s Ethernet interface that enables both data transmission and power supply via just one twisted pair of wires The SPoE Single Pair Power over Ethernet interface is particularly suitable for applications with space and weight restrictions such as in automotive industrial and IoT devices simplifying installation and saving costs The reference design consists of two boards one representing the Power Source Equipment PSE and the other the Powered Device PD Both boards fully comply with the requirements of the PoDL IEEE 802 3bu and SPoE IEEE 802 3cg standards as well as the applicable security requirements They each offer a 10 100 Mbit s Ethernet a 10 Mbit s SPE and a USB 3 1 connection The PSE operates in PoDL class 12 with up to 30 Vand 8 3 W It can recognize and classify the PD and thus supply the required current The EMC behaviour of the two boards was tested by measuring emissions and immunity to continuous disturbances and transients This ensures a high level of interference immunity so that the functionality of the boards is guaranteed despite external interference The SPoE reference design is also characterized by particularly low radiated and conducted interference emissions ak Würth Elektronik eiSos Hall A6 Booth 502 ❚ Fischer Connectors USB 3 2 connections Fischer Connectors offers a wide range of robust solutions for highspeed data transmission On display are USB 3 2 connectors and cable assembly solutions that are part of the existing Fischer MiniMax Fischer UltiMate and Fischer Core series New solutions are for the USB 3 2 Gen 2 standard with transfer rates of up to 10 Gbit s The connectors and cable assemblies are designed for demanding applications in areas such as medicine industry the military and measurement technology The Fischer Core connectors offer nine pins in a 15 5 mm connector connector size 1031 and are resistant to chemicals and designed for sterilization processes Applications include surgical devices USB 3 cameras in orthopaedic surgery and endoscopy as well as metrology applications in production lines or contaminated area inspections With a particularly compact design the Fischer MiniMax series connectors comprise nine pins in a 12 9 mm connector or twelve signal and power pins in a 14 9 mm connector that supports power up to 8 A They are particularly suitable for applications where size weight and power consumption SWaP are critical – such as portable computers and high performance LiDARs The robust lightweight Fischer UltiMate series connectors with nine pins in an 18 5 mm connector provide 360-degree EMI shielding and protection against shock vibration and corrosion They are used in civilian and military drones equipped with USB-3 cameras and other MIL-SPEC compliant devices ak
