The ultimate pocket-sized lab bench supply. This 80W Buck-Boost converter takes any DC input (6V-36V) and outputs a precise, stable voltage (0.6V-36V) regardless of input fluctuations. Features a rich LCD for monitoring Voltage, Current, Power, and Capacity (Ah).
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
Model: ProMax XY-SK80.
Input Voltage: DC 6.0V - 36V.
Output Voltage: DC 0.6V - 36V (Adjustable).
Output Current: 0 - 5.0A (Adjustable Current Limit).
Output Power: 80W (Natural cooling).
Efficiency: ~88%.
Display: Digital LCD (Voltage, Current, Watts, Ah Capacity, Run Time).
Control: Digital Rotary Encoder (Push-button interface).
Protections: Anti-Reverse Input, Anti-Backflow Output, Short Circuit, OVP, OCP, OTP.
Quality Advantage & Differentiation: Why choose the SK80?
Digital Precision: Forget fiddly potentiometers. The rotary encoder allows you to dial in voltage to the exact 0.01V and current to 0.001A.
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.
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:
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.
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.
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.
Call to Action (CTA): Take control of your power. Add the ProMax SK80 Buck-Boost Module to your cart today and build the reliable power supply your projects deserve!
