DC-Tischnetzteil der Serie Array 367XA

What are the key differences between the four Array 367XA models available?

The Array 367XA series comprises four models optimised for different voltage and current requirements: the 3672A (0-35V, 0-22.5A, 787.5W), 3673A (0-80V, 0-10A, 800W), 3674A (0-120V, 0-6.5A, 780W), and 3675A (0-200V, 0-4A, 800W). Each model maintains the same professional feature set including SCPI compatibility, 10-memory storage, and multiple interface options. The 3672A excels in high-current applications such as power electronics testing, the 3673A and 3674A models provide intermediate voltage ranges suitable for component testing, whilst the 3675A delivers the highest voltage capability ideal for high-voltage component burn-in, insulation testing, and reliability validation. All models feature identical programming resolution and protection systems, with the 3675A offering <20mVrms voltage ripple performance for sensitive high-voltage applications.

What applications benefit most from the Array 367XA's high power and low noise combination?

The Array 367XA excels in applications requiring both substantial power delivery and precision performance, including power electronics development, LED driver testing, battery simulation, and component burn-in procedures. The combination of 500W+ power capability with <10-16mVrms noise makes it particularly suitable for analogue circuit characterisation, where high currents must be delivered without introducing measurement artifacts. Automated test environments benefit from the SCPI compatibility and memory storage features, enabling sophisticated test sequences for production testing and reliability validation. Research laboratories utilise the wide voltage ranges and precise control for component evaluation and failure analysis. The switching-mode efficiency reduces heat generation in temperature-sensitive environments whilst maintaining the low noise essential for accurate measurements.

How does the Array 367XA's user interface enhance laboratory productivity?

The Array 367XA features an intuitive high-definition LCD display with dedicated voltage and current adjustment controls, eliminating the menu navigation complexity found in many competitive products. Direct parameter entry via numerical keypad enables rapid setting changes without scrolling through multiple display screens. The display simultaneously shows voltage, current, power output, and operating status, providing comprehensive information at a glance. Front-panel operation includes dedicated output enable/disable control, memory recall buttons, and protection status indicators. The interface design prioritises frequently used functions for immediate access whilst maintaining professional appearance suitable for calibrated laboratory environments. This user-centric design significantly reduces setup time and operational errors compared to menu-driven alternatives.

What voltage and current programming resolution does the Array 367XA provide?

The Array 367XA delivers professional-grade programming resolution of 1mV for voltage setting and 1mA for current setting across all three models in the series. This high resolution enables precise parameter control essential for component characterisation, device testing, and research applications. The programming accuracy specifications include 0.03% + offset for voltage and 0.5% + offset for current, ensuring reliable and repeatable measurements. Combined with excellent line and load regulation (2-3mV voltage, 1-2mA current), the Array 367XA provides the precision control capabilities typically found in premium laboratory instruments whilst maintaining the efficiency and compact size advantages of switching-mode topology.

What protection features does the Array 367XA include for safe operation?

The Array 367XA incorporates comprehensive protection systems including over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP), and reverse voltage protection. The OVP system monitors output voltage continuously and immediately shuts down the supply if preset limits are exceeded, protecting connected devices from damage. OCP provides precise current limiting with foldback characteristics to prevent thermal stress during fault conditions. The thermal protection system monitors internal temperature and implements controlled shutdown if safe operating limits are approached. All protection thresholds are user-programmable via front panel or SCPI commands, with protection status clearly indicated on the display and available for remote monitoring.

How many operating configurations can the Array 367XA store and recall?

The Array 367XA features comprehensive memory storage capability, allowing users to store and recall up to 10 complete operating configurations. Each stored setting includes voltage setpoint, current limit, output state, and protection parameters, enabling rapid configuration changes for repetitive testing procedures. The memory system stores settings in non-volatile memory, ensuring configurations remain available after power cycling. Settings can be recalled either through front-panel operation or remotely via SCPI commands, making the feature valuable for both manual laboratory work and automated test sequences. This memory capability significantly enhances productivity in applications requiring frequent parameter changes between different test conditions.

What remote control interfaces does the Array 367XA support for laboratory automation?

The Array 367XA provides comprehensive connectivity options including standard RS-232 serial interface, optional USB, and optional GPIB (IEEE-488) interfaces. All interfaces support full SCPI command compatibility, enabling integration with popular automation platforms including LabVIEW, Python, MATLAB, and proprietary test software. The RS-232 interface operates at standard baud rates with hardware handshaking support, whilst the optional USB interface provides plug-and-play connectivity with modern computer systems. GPIB compatibility ensures seamless integration with established automated test equipment installations. Multiple interfaces can operate simultaneously, allowing local monitoring whilst maintaining automated control.

How does the Array 367XA achieve low noise performance despite using switching-mode topology?

The Array 367XA employs advanced switching-mode design with sophisticated filtering and regulation circuits to achieve exceptionally low noise performance rivalling linear power supplies. The 3672A model delivers <10mVrms voltage ripple and noise, whilst the 3673A and 3674A maintain <16mVrms across the full 20Hz to 20MHz bandwidth. This performance is achieved through high-frequency switching combined with multi-stage output filtering, active regulation circuits, and careful PCB layout optimisation. Unlike traditional linear supplies that achieve low noise through brute-force regulation, the Array 367XA's intelligent switching architecture maintains high efficiency (>80%) whilst delivering precision laboratory-grade noise specifications essential for sensitive analogue circuit testing

How does the Array 367XA's SCPI implementation compare to other professional power supplies?

The Array 367XA features comprehensive SCPI (Standard Commands for Programmable Instruments) compliance, matching the automation capabilities found in premium test equipment. SCPI standardisation ensures the power supply integrates seamlessly with automated test systems, LabVIEW environments, and Python-based control software. Unlike proprietary command sets, SCPI provides device independence and consistent programming syntax across different manufacturers' equipment. The Array 367XA's SCPI implementation includes full voltage, current, and protection control commands, enabling sophisticated test sequencing and data logging applications typically reserved for more expensive laboratory instruments.

What makes the Array 367XA series superior to premium competitors like Keysight E36200?

The Array 367XA delivers significantly higher power output (500W+) compared to Keysight's E36200 series (200-400W maximum), whilst maintaining professional-grade low noise performance of <10mVrms voltage ripple. Unlike Keysight's autoranging approach, the Array 367XA provides dedicated voltage ranges optimised for specific applications, offering superior current capability with up to 22.5A output. The Array series includes full SCPI compatibility and multiple interface options (RS-232, USB, GPIB) at a more accessible price point than premium alternatives, making it ideal for professional laboratories requiring high-power testing capabilities without compromising on precision or automation features.
