Are you still using standard DC power supplies that lack remote control capabilities, are prone to accidental parameter changes, and exhibit high ripple? The KUAIQU SPPS3010D-232, SPPS2001D-232, and SPPS3001D-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.

1️⃣Built-in RS232 and USB interfaces; free PC-based remote control software included

The 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 error

Unlike 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 Lockout

Store 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 operation

Equipped 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 delivery

Utilizing 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 adjustment

A 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.
