ProMax Buck Boost Converter Module SK80 80W 5A Adjustable DC-DC Regulator with LCD Display

Quick Introduction: Transform any DC power source into a precision laboratory power supply with the ProMax SK80. Unlike standard "Buck" (step-down) or "Boost" (step-up) modules that operate in only one direction, the SK80 features a true Buck-Boost architecture. It can take a 12V input and output 5V or 24V seamlessly. With a massive 80W power rating and a digital rotary encoder for precision control (no tiny screwdrivers needed!), it is the most versatile power tool for any maker's workbench.

Detailed Specifications

• Protections: Anti-Reverse Input, Anti-Backflow Output, Short Circuit, OVP, OCP, OTP.

Quality Advantage & Differentiation: Why choose the SK80?

1. Digital Precision: Forget fiddly potentiometers. The rotary encoder allows you to dial in voltage to the exact 0.01V and current to 0.001A.

2. Full Information Display: The screen doesn't just show V and A; it calculates Power (Watts), tracks Energy (Wh), and measures Capacity (Ah)—ideal for testing battery capacity.

3. Solar Ready: Built-in Anti-Backflow protection means you can connect it directly to a battery for charging without adding external diodes. It handles fluctuating solar panel voltage (e.g., 18V panel dropping to 14V) while keeping the output stable.

Key Applications & Usage

• DIY Bench Power Supply: Use an old laptop charger (19V) to create a fully adjustable 0-36V lab supply.

• Solar Battery Charger: Regulate variable solar panel output to safely charge Li-Ion, LiFePO4, or Lead-Acid batteries with CC/CV curves.

• LED Driver: Drive high-power LEDs with precise Constant Current (CC) to prevent burnout.

• Device Testing: Simulate low-battery or over-voltage conditions to test how your Arduino/Raspberry Pi projects behave.

What's Included & Required

• Included: 1x ProMax SK80 Buck-Boost Converter Module.

• Required: DC Power Source (Adapter, Battery, or Solar Panel), Output Wires/Clips.

The "Virtual Technician" Support Panel

• ⚠️ CRITICAL USAGE WARNINGS:

  1. Input Low Voltage Protection (LVP): The default LVP is often set around 4.8V. If using a battery as input, adjust LVP to prevent over-discharging your source battery.

  2. Charging Mode: When charging batteries, you MUST set the Current Limit (CC) before connecting the battery. Connect the battery to the output only after the module is powered on.

  3. Heat Management: While rated for 80W, sustained operation above 50W gets hot. Ensure good airflow. The internal fan kicks in automatically at certain thresholds.

• Troubleshooting: Output turn off automatically? Check if you triggered a protection limit (OVP/OCP). Long-press the knob to check if "OP" (Over Power) or "OU" (Over Voltage) limits are set too low.
