Product Description
Product Overview
The Mini DC Auto Range Programmable DC Power Supply is a premium, highly stable, and cost-effective energy solution designed for professional testing, line calibration, and development environments. Featuring a 4-digit LED display for synchronized real-time tracking of voltage, current, and power, it incorporates customizable Over-Voltage Protection (OVP) and Over-Current Protection (OCP) threshold systems. Engineered for precision and rigorous industrial reliability, this series serves as an essential, foundational supply for academic research laboratories, industrial automation production lines, and high-density semiconductor test benches. Additionally, it offers optional programmable interfaces to seamlessly bridge individual hardware testing with complex, automated remote-control test suites.

Key Product Features
  • Constant Power & Wide Range Utility: Engineered with advanced 300W auto-ranging capabilities, delivering flexible voltage and current profiles. One single unit effectively replaces multiple traditional fixed-range power supplies to optimize workbench space and lower equipment costs.

  • Pre-Settable Voltage & Current Parameters: Operators can dynamically pre-set precision output voltage and current parameters while the output state is safely turned off, mitigating accidental power spikes or live-connection loads.

  • Dedicated Hardware Keypad Lock: A simple long-press activates a centralized console safety lock, freezing the tuning interface to eliminate human tuning variance, stray contact, or parameter shifting during long-duration automated testing sequences.

  • Dual OVP/OCP Protection Mechanisms: Independent, easily configurable protection circuits with visual alert indicators that automatically arrest active power delivery when target thresholds are crossed, safely outputting alert logs directly to the console.

  • Flexible Group Profile Recall (M1-M3): Built-in non-volatile storage presets save up to 3 discrete setup profiles. Users can instantly recall pre-mapped electrical tests via the faceplate, accelerating production turn times and structural diagnostic loops.

  • Independent Output Termination Panel: Designed with an isolated hardware ON/OFF output rocker completely distinct from the master rear switch. This enables rapid, wear-free signal gating while continuously preserving active device settings.
