The KUAIQU SPPS-D-232 series are programmable regulated power supplies featuring native RS232 ports, specifically designed for laboratory automated testing, electronics repair, high-voltage component burn-in, and industrial system debugging. They support remote parameter control and data logging via PC software and come equipped with a high-precision 4-digit digital display, parameter locking, and multiple memory presets. These units cover a full range of applications—from low-voltage/high-current to high-voltage/low-current scenarios—and hold dual CE and FCC certifications.Description:1. Color LCD screen, 4-digit display, with power display.2. Single-knob encoder for precise digital signal adjustment.3. USB-A 5V 2A output port for charging mobile phones.4. Four memory function buttons ("M1/M2/M3/M4") for one-button adjustment of current and voltage settings.5. "LOCK" screen lock button to prevent accidental touches that could cause changes in output current and voltage and damage to appliances.6. "V/A" current/voltage switch button for switching between current and voltage values using the single-knob encoder.7. "On/Off" output switch button (some models use "OUTPUT") for safer current and voltage output.Specification:Package Includes:1Power supply1Power Adapter(EU/AU/UK/US optional)2output line(gift)1Instruction Book (English)1USB Cable1Package Box1*Certificate of conformity1️⃣Built-in RS232 and USB interfaces; free PC-based remote control software includedThe unit features standard RS232 and USB communication interfaces, eliminating the need for additional adapter modules. Paired with the manufacturer's free PC software, it enables remote voltage and current adjustment, real-time operational data monitoring, automatic test report generation, and scheduled start/stop functions. It is ideally suited for automated burn-in testing and long-term unattended experiments, resolving the inefficiencies associated with manual parameter adjustments. It also supports Python-based secondary development for integration with industrial control systems, meeting customized industrial requirements.2️⃣High-precision 4-digit display with minimal parameter errorUnlike the simple 3-digit displays found on many market alternatives, this entire series features independent 4-digit LED displays for three channels, providing simultaneous, real-time monitoring of voltage, current, and power without the need to toggle between screens. It offers a voltage setting resolution as fine as 100mV and a current resolution as low as 1mA, with a voltage readback accuracy of ≤0.01% + 30mV. Parameter drift under load fluctuations is negligible, making the series ideal for testing components—such as chips, sensors, and precision circuit boards—that demand rigorous power supply accuracy.3️⃣4-Group Parameter Memory & Panel LockoutStore up to four sets of frequently used voltage and current parameters for instant recall—eliminating the need for repeated fine-tuning—making this ideal for the sequential repair of diverse electronic products and multi-batch sample testing. A built-in panel lock function disables all knobs and buttons upon activation, preventing accidental parameter changes caused by multiple operators or equipment movement, thereby ensuring the consistency of test data.4️⃣Independent output on/off switch for safer operationEquipped with a physically independent output switch, the unit allows the output to be disabled during parameter configuration; power can be enabled with a single click once calibration is verified. This prevents damage to precision components—such as LEDs, capacitors, and sensors—caused by transient high voltage or high current during setup, and eliminates the need to power-cycle the entire unit, thereby extending the power supply's service life.5️⃣Low ripple and low noise for clean power deliveryUtilizing a high-frequency synchronous rectification switching circuit, the voltage ripple across the full 20Hz–20MHz bandwidth peaks at just 140mVrms—far below standard industry benchmarks. Free from spurious interference, it prevents data distortion in precision analog circuits and sensor signal drift, making it suitable for signal detection and R&D experiments involving low-level circuitry.6️⃣Encoder knob for precise current and voltage adjustmentA single digital encoder knob enables precise control; rotate the knob for fine adjustments (0–9), or press it to increment the value by 10. Press the "V/A" button to toggle between current and voltage settings for adjustment.About Shipment:We will ship your package within 1-2 working days.
